Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a continuation application of PCT/JP2008/058494, filed May 9, 2008, which claims priority to Japanese Patent Application No. 2007-124452, filed May 9, 2007. The contents of these applications are incorporated herein by reference in there entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an advertisement information managing method, an advertisement information managing system, a call receiving method and a call receiving system. 
     2. Discussion of the Background 
     A pay per click system has been used as one of the methods of advertising using web pages on the Internet. The pay per click system is a system in which an advertising agency charges an advertisement fee to an advertiser according to the count which an item of advertisement information displayed on the web page is clicked. 
     For example, when advertisement information of the advertiser is posted on a web page of an advertisement-providing site and a user who has viewed the page selects (clicks) the advertisement information, the advertisement information is linked to a website managed by the advertiser and the user can view the detailed information regarding the advertisement information. And, the advertiser pays an advertisement fee to the administrator of the portal site according to the count of clicks made on the advertisement information. 
     This method is frequently used in portal (entrance) sites that have many users (viewers) and can obtain a high advertisement effect. The administrator of the portal site sets frames for advertisements in a part of the site page, runs advertising by lending the frames for advertisements to advertisers, and collects advertisement fees according to the count of clicks made on the advertisement information. 
     However, this pay per click system has a problem in that, when the advertiser does not have their own site, no site can be set to be linked to and no detailed information regarding the advertisement information can be provided. Because payment of an advertisement fee is generated simply through clicks made on advertisement information, “direct contact with users (clients)” cannot be obtained as an effect for the cost of advertising, either. 
     Moreover, because the advertisement fee is generated according to the count of clicks made even when a user unintentionally clicks the advertisement information or intentionally repeats clicking, the association between the advertisement effect and the advertisement fee may be decreased. 
     Therefore, a system has also been proposed in which a phone number corresponding to each advertiser is posted on a web page of an advertisement-providing site along with the advertisement information, and when a user who has seen it calls the advertiser, the advertisement fee is charged according to the connection success of the phone call. Furthermore, one of the systems with this method of advertising is called Pay Per Call system, and it is disclosed in, for example, Japanese Patent Application Publication No. 2005-115945. 
     However, when posting advertisement information in many advertisement-providing sites, if all posted phone numbers are the same phone numbers, it is impossible to distinguish which advertisement-providing site the user has seen to make the phone call. Therefore, there is a problem in that it is impossible to ascertain which advertisement-providing site has a high advertisement effect and which advertisement-providing site has a low advertisement effect. 
     Therefore, a method has been proposed in which different phone numbers are allocated for each item of advertisement information and posted on different advertisement-providing sites in order to ascertain, according to the phone number the user calls, which advertisement-providing site the user has seen to make the phone call. According to this method, the advertisement effect of each advertisement-providing site can be ascertained. 
     However, in recent years, there are many advertisement-providing sites. For example, when an advertiser posts advertisement information of their company on 10,000 or 100,000 advertisement-providing sites, a large amount of work is required just to allocate different phone numbers to each of a number of these sites, causing a problem of low work efficiency. Moreover, for example, ascertaining the difference of the advertisement effect for each different time, each different day of the week, etc. may be needed by updating the posted information on the specific advertising-providing site. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the present invention, an advertisement information managing method includes generating a plurality of identification information, generating the plurality of advertisement information that respectively indexes the plurality of identification information by combining the plurality of identification information with basic advertisement information respectively, and cross-checking the plurality of identification information with input information in the call that is made according to one of the plurality of advertisement information. 
     According to another aspect of the present invention, an advertisement information managing system includes an identification information-generating part and an information-verifying part. The identification information-generating part is configured to generate a plurality of identification information. The information-verifying part is configured to cross-check the plurality of identification information with input information in a call that is made according to one of the plurality of advertisement information generated in order to index the plurality of identification information respectively, by combining the plurality of identification information with basic advertisement information.

     DESCRIPTION OF EMBODIMENTS 
     Embodiment 1 
     The embodiments will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings. 
     An advertisement information managing system S using an advertisement information managing method according to Embodiment 1 of the present invention will now be described with reference to the drawings. Furthermore, in the present specification, a server refers to a server computer and a site (a “website” and an “Internet site” are also generally synonymous) refers to a collective entity of web pages established virtually within the server. A web page can be specified by an URL and is a virtual information-providing medium in which various types of information, such as character information and image information, are posted. As used herein, “posting on a website” is used in a synonymous manner with “posting on a web page”, and “viewing a website” is used in a synonymous manner with “viewing a web page.” 
       FIG. 1  is a schematic diagram illustrating the overall configuration of the advertisement information managing system S. This advertisement information managing system S is roughly configured with an advertisement information management server  1  and a call receiving server (call receiving system)  2 , and the advertisement information management server  1  is connected to an advertiser&#39;s server  3 , an agent&#39;s server  4 , advertisement-providing servers  5   a  to  5   c , and a user&#39;s computer  6  via the Internet W in a manner that allows for information to be received and sent. The advertiser and the user have an advertiser&#39;s phone  7  and a user&#39;s phone  8 , respectively, which are connected to the call receiving server  2  via a telephone network T. 
     The advertiser&#39;s server  3  is a server computer managed by an advertiser A, and an advertiser&#39;s website (advertiser&#39;s site)  3   a  is established internally as a second Internet site. This advertiser&#39;s site  3   a  is linked to advertisement images (advertisement information)  9   a  to  9   c , which are described below, and the content of the advertiser&#39;s site  3   a  (detailed information of the advertisement information) is displayed on the user&#39;s computer  6  when a user U clicks on the advertisement images  9   a  to  9   c . Moreover, the advertiser A can send a banner image (basic advertisement information)  10  to the agent&#39;s server  4  via the advertiser&#39;s server  3 . 
     This banner image  10  is, for example, a decorative advertisement image to which various colors and patterns have been added to gather the attention of users or an illustrative advertisement image for briefly describing the content of the advertisement of the advertiser A. Most banner images are usually still images, and while it is understood that they may be moving images configured in the abovementioned various file formats, they will be described in the present Embodiment 1 on an assumption that they are still images. 
     The agent&#39;s server  4  is a server computer managed by the advertising agent and connected to a plurality of advertisement-providing servers  5   a  to  5   c  via the Internet W and comprehensively manages these advertisement-providing servers  5   a  to  5   c . The agent&#39;s server  4  has a function to receive the banner image  10  from the advertiser&#39;s server  3 . Additionally, it sends the banner image  10  to the advertisement information management server  1  and receives the plurality of advertisement images  9   a  to  9   c  combined with a plurality of items of identification information  11   a  to  11   c  from the advertisement information management server  1 . Furthermore, it also has a function to send the plurality of advertisement images  9   a  to  9   c  to each of the plurality of advertisement-providing servers  5   a  to  5   c.    
     The agent&#39;s server  4  internally includes a memory device that is not shown. Inside the memory device, an advertisement-providing-server management database  4   a  is established as shown in  FIG. 2 . In this advertisement-providing-server management database  4   a , allocation numbers  14   a  to  14   c  of each of the advertisement-providing servers  5   a  to  5   c  and each of the identification information  11   a  to  11   c  within the advertisement images  9   a  to  9   c  sent to each of the advertisement-providing servers  5   a  to  5   c  are included after being mutually associated with each other. 
     The advertisement-providing servers  5   a  to  5   c  are server computers each managed by an advertisement provider, and advertisement-providing sites  12   a  to  12   c  are established inside each of the servers as first Internet sites.  FIG. 3  is an example of a display screen of a web page of the advertisement-providing site  12   a.    
     This advertisement-providing site  12   a  is referred to as a so-called portal site, and various types of information are posted within the page. An advertisement frame  13   a  is placed within the page, and the advertisement image  9   a  received from the agent&#39;s server  4  is posted within the advertisement frame  13   a.    
     The advertisement image  9   a  is configured by combining the banner image  10  with the identification information  11   a  and has a function to provide the identification information  11   a  to the user U while gathering the attention of the user U. The identification information  11   a  is, for example, phone number information “0125423-0011002553” having a total of 17 digits that include a server identification number as the first 7 digits and an advertisement identification number as the second 10 digits. The user U can call the advertiser A of this advertisement image  9   a  by making a call according to this identification information  11   a.    
     For the method of proving the identification information  11   a  in the advertisement-providing site  12   a , several methods may be applied. For example, as shown in  FIG. 3 , there is a method in which the identification information  11   a  is displayed by being posted on the advertisement-providing site  12   a  with the banner image  10 . For example, there is a method in which, as shown in  FIG. 4A , in a normal state (i.e., when the mouse pointer M is not placed on the banner image  10 ), only the banner image  10  is displayed and the identification information  11   a  is not displayed and, as shown in  FIG. 4B , when the mouse pointer M is moved onto the banner image  10 , the identification information  11   a  is displayed in a balloon. For example, there is a method in which, as shown in  FIG. 5A , in a normal state (i.e., before the banner image  10  is clicked using the mouse), only the banner image  10  is displayed and the identification information  11   a  is not displayed and, as shown in  FIG. 5B , when the banner image  10  is clicked using the mouse, another window appears and the identification information  11   a  is displayed within the window. 
     Moreover, if the after mentioned identification information-generating part has a function to generate the identification information  11   a  and concurrently generate a QR code  17   a  corresponding to the identification information  11   a , as shown in  FIG. 6 , a method for displaying the QR code  17   a  within the banner image  10  may also be applied. For example, if the user U has a cell phone and this cell phone has a QR code-reading function and a phone-to function, such a method of providing the identification information  11   a  is convenient for the user U. 
     When the user U connects to the advertisement-providing site  12   a  using the user&#39;s computer  6  and the banner image  10  is displayed on the display screen, the user U uses the QR code-reading function of the cell phone to read the QR code  17   a  within the banner image  10 . A phone number as the identification information  11   a  corresponding to the QR code  17   a  is then displayed on the display screen of the cell phone. When the user U clicks the phone number, they can easily call the phone number through the phone-to function. 
     The advertisement images  9   b ,  9   c  are similarly posted on the advertisement-providing sites  12   b ,  12   c . The banner image  10  in the advertisement images  9   b ,  9   c  are common to the one in the advertisement image  9   a , but each item of the identification information  11   b ,  11   c  has a different number. In other words, the identification information  11   b  has “0125423-0011002554” and the identification information  11   c  has “0125423-0011002555.” Therefore, it is possible to ascertain which advertisement effect was effective among the advertisement images  9   a  to  9   c  by ascertaining which number the user U has called. 
     Obviously, the identification information  11   a  to  11   c  is not limited to 17-digit phone number information and may be 2- to 4-digit information that is a part of a phone number or an input number of a few digits for the user U to input into the destination server after making the call. Moreover, if the destination server has a voice-recognition function, the identification information  11   a  to  11   c  may also be a keyword for the user U to say during the call. As the other configurations of the advertisement-providing sites  12   b ,  12   c  are identical to that of the advertisement-providing site  12   a , the descriptions thereof are omitted. 
     Furthermore, in the present Embodiment 1, it has been described that the agent&#39;s server  4  is managed by the advertising agent and the advertisement-providing servers  5   a  to  5   c  are managed by the advertisement providers as if they are different servers, but it is understood that they do not have to be different. For example, one advertising agent may manage the plurality of advertisement-providing servers  5   a  to  5   c  and eliminate the agent&#39;s server  4 , and each of the advertisement-providing servers  5   a  to  5   c  may have the functions of the agent&#39;s server. 
     The user&#39;s computer  6  is a computer managed and used by the user U who views the advertisement-providing sites  12   a  to  12   c . When the user U views the advertisement-providing site  12   a  via the Internet W using the user&#39;s computer  6 , the advertisement image  9   a  is displayed on the display screen of the user&#39;s computer  6  with various types of information within the advertisement-providing site  12   a.    
     In addition, when the user U is interested in the advertisement image  9   a  and calls the displayed number “0125423-0011002553” using the user&#39;s phone  8  at home, it is received by the call receiving server  2  and the phone call is made to the advertiser A. 
     The advertisement information management server  1  is a server computer that configures the principal part of this advertisement information managing system S and is connected to the agent&#39;s server  4  via the Internet W. This advertisement information management server  1  internally includes a central processing unit (CPU), which is not shown, and the CPU functions as the identification information-generating part and the information-verifying part. 
     The identification information-generating part has a function for generating the plurality of items of identification information  11   a  to  11   c . Each item of this identification information  11   a  to  11   c  is unique information and is 17-digit phone number information as described above in the present Embodiment 1. The identification information-generating part also has a function to send the generated identification information  11   a  to  11   c  to the agent&#39;s server  4 . 
     A memory device, which is not shown, is provided inside the advertisement information management server  1 . An identification information database  1   a  is established within the memory device as shown in  FIG. 7 . The generated identification information  11   a  to  11   c  is retained within this identification information database  1   a , and information-recording parts  15   a  to  15   c  are provided corresponding to each item of the identification information  11   a  to  11   c . The advertisement information management server  1  has a function to combine each of the plurality of items of identification information  11   a  to  11   c  with the banner image  10  in order to generate the plurality of advertisement images  9   a  to  9   c  when it receives the banner image  10  from the agent&#39;s server  4 , and it sends the advertisement images  9   a  to  9   c  to the agent&#39;s server  4 . Furthermore, it is understood that the banner image  10  may be combined with the identification information  11   a  to  11   c  within the agent&#39;s server  4  rather than the advertisement information management server  1 . 
     On the other hand, the advertisement information management server  1  is also connected to the call receiving server  2 . In the present Embodiment 1, the advertisement information management server  1  is directly connected to the call receiving server  2 , but it is understood that it may be connected via the Internet W. When the 17-digit phone number information made by the user U is received as input information  16  in the call receiving server  2 , the information-verifying part cross-checks the input information  16  with the identification information  11   a  to  11   c  within the identification information database  1   a . In addition, when the input information  16  and the identification information  11   a  match (i.e., when the input information  16  input into the user&#39;s phone  8  by the user U corresponds to the identification information  11   a ), history information such as the time and date of the call, the phone number (phone number of the caller) of the origin of the call (i.e., the user&#39;s phone  8 ), and the duration of the call is recorded in the information-recording part  15   a  corresponding to the identification information  11   a.    
     According to the history information of this identification information database  1   a , it is possible to ascertain when and how many times who has called according to which identification information  11   a  to  11   c . In other words, the degree of the advertisement effect of each of the advertisement images  9   a  to  9   c  can be ascertained. 
     By sending this history information to the agent&#39;s server  4  and cross-checking it with the advertisement-providing-server management database  4   a  within the agent&#39;s server  4 , it is also possible to ascertain the degree of the advertisement effect of each of the advertisement-providing sites  12   a  to  12   c.    
     The call receiving server  2  is a server computer for receiving the call from the user&#39;s phone  8  of the user U and is connected to the advertisement information management server  1  and the telephone network T. The user&#39;s phone  8  and the advertiser&#39;s phone  7  of the advertiser A are also connected to this telephone network T, and the user U may call the advertiser A via the call receiving server  2 . 
     The call receiving server  2  internally includes a central processing unit (CPU), which is not shown, and the CPU functions as the call receiving part, the input information-extraction part, and the information-sending part. 
     The call receiving part has a function to receive the call that is made using the user&#39;s phone  8  and relays and forwards the call to the advertiser&#39;s phone  7 . 
     Specifically, when the user U inputs the 17-digit phone number information “0125423-0011002553” into the user&#39;s phone  8 , a call is made to the call receiving server  2  according to the first 7-digit server identification number. The call receiving part recognizes it as a call to the advertiser A based on the second 10-digit advertisement identification number without receiving the call and forwards the call to the advertiser&#39;s phone  7 . As the call receiving part does not receive the call, the user U may make the phone call smoothly as if they directly called the advertiser A without being aware of the relay operation of the call receiving server  2 . At this time, the call receiving part acquires the phone number information “0125423-0011002553” input by the user U. 
     The input information-extraction part has a function to extract the phone number information as the input information  16  when it receives the phone number information in the call receiving part. In the present Embodiment 1, all of the 17 digits of the phone number information input into the user&#39;s phone  8  by the user U are extracted as the input information  16 , but it is understood that a part of the phone number information may be extracted as the input information  16  or voice information stated by the user U according to information such as a keyword may be extracted as the input information  16 . 
     For example, when the user U inputs the first 7-digit server identification number to make a call, the call receiving server  2  receives it, and during the automatic response, the second 10-digit advertisement identification number may be input, the call may be forwarded to the advertiser&#39;s phone  7  according to the advertisement identification number, and the second 10-digit advertisement identification number may be extracted as the input information  16  by the input information-extraction part. 
     Moreover, in cases in which the call receiving server  2  has a voice-recognition function, the user U may say the keyword as the input information  16  during the automatic response in order to cause the voice information to be extracted as the input information  16  by the input information-extraction part. For example, it is possible to provide a configuration in which, when the user U says a keyword such as “discount,” a certain privilege is given to the user U by the advertiser A. In this case, the identification information  11   a  to  11   c  within the advertisement images  9   a  to  9   c  posted on the advertisement-providing sites  12   a  to  12   c  must be set to a keyword such as “discount.” 
     Furthermore, in the present Embodiment 1, even when the phone number information set as the identification information is “0125423-0011002553,” “0125423-0011002554,” or “0125423-0011002555,” the call is forwarded to the advertiser A. In addition, it is possible to ascertain which of the advertisement images  9   a  to  9   c  the user U has called according to due to the differences in the numbers of the phone number information, specifically the final digit. 
     The information-sending part has a function to send the input information  16  extracted by the input information-extraction part to the advertisement information management server  1 . The input information  16  is cross-checked with the identification information  11   a  to  11   c  within the identification information database  1   a  by the information-verifying part within the advertisement information management server  1  at the destination. 
     Furthermore, in the present Embodiment 1, an example has been described that is configured so that the call receiving server  2  extracts the input information in the call and sends the input information to the advertisement information management server  1 , but it is understood that a configuration may be used in which the advertisement information management server  1  includes the input information-extraction part, and when it receives call information in the call receiving server  2 , it extracts the input information from the information. 
     Moreover, in the present Embodiment 1, an example has been described in which the advertisement information management server  1  and the call receiving server  2  are configured as separate bodies, but it is understood that a configuration may be used in which the functions of both are implemented with one server computer. Furthermore, one server computer may function as the agent&#39;s server  4  in addition to the advertisement information management server  1  and the call receiving server  2 . 
     Next, the operations of the advertisement information managing system S using the advertisement information managing method according to this Embodiment 1 will be described using the flowchart shown in  FIG. 8 . 
     The advertiser&#39;s server  3  sends the banner image  10  to the agent&#39;s server  4  according to the request for posting an advertisement from the advertiser A (S.  1 ). The agent&#39;s server  4  sends the received banner image  10  to the advertisement information management server  1  (S.  2 ). The advertisement information management server  1  generates the plurality of items of identification information  11   a  to  11   c  (S.  3 ), establishes the identification information database  1   a , and internally retains the identification information  11   a  to  11   c  (S.  4 ). It then combines the identification information  11   a  to  11   c  with the received banner image  10  in order to generate the plurality of advertisement images  9   a  to  9   c  (S.  5 ) and sends the advertisement images  9   a  to  9   c  to the agent&#39;s server  4  (S.  6 ). 
     When the agent&#39;s server  4  receives the advertisement images  9   a  to  9   c , it sends the advertisement images  9   a  to  9   c  to each of the advertisement-providing servers  5   a  to  5   c  (S.  7 ) and establishes the advertisement-providing-server management database  4   a  with the advertisement images  9   a  to  9   c  associated with the allocation numbers  14   a  to  14   c  specific to each of the servers for providing the advertisement at the destination (S.  8 ). 
     The advertisement-providing servers  5   a  to  5   c  post the received advertisement images  9   a  to  9   c  on each of the advertisement-providing sites  12   a  to  12   c  (S.  9 ). 
     The user U uses the user&#39;s computer  6  to access the advertisement-providing server  5   a  and views the advertisement-providing site  12   a . If the user is interested in the advertisement image  9   a  posted on the advertisement-providing site  12   a , the user U then inputs the identification information  11   a  within the advertisement image  9   a  into the user&#39;s phone  8  as the phone number in order to make a call (S.  10 ). 
     The call is connected to the call receiving server  2  according to the first 7-digit server identification number of the identification information  11   a , and the call receiving server  2  receives the call (S.  11 ). The call receiving server  2  then forwards the call to the advertiser&#39;s phone  7  according to the second 10-digit advertisement identification number of the identification information  11   a  (S.  12 ). The user&#39;s phone  8  and the advertiser&#39;s phone  7  are mutually connected, allowing the user U and the advertiser A to talk. 
     At the same time, the call receiving server  2  acquires the phone number input by the user&#39;s phone  8  and extracts the input information  16  from the phone number (S.  13 ). In the present Embodiment 1, the entire input phone number is extracted as the input information  16 . The input information  16  is then sent to the advertisement information management server  1  (S.  14 ). 
     The advertisement information management server  1  cross-checks the received input information  16  with the identification information  11   a  to  11   c  within the identification information database  1   a  (S.  15 ) and records history information such as the time and date of the call, the phone number of the originator, and the duration of the call in the information-recording part  15   a  of the identification information  11   a  matching to the input information  16  (S.  16 ). 
     Embodiment 2 
       FIG. 9  is a schematic diagram illustrating the overall configuration of an advertisement information managing system S&#39; using the advertisement information managing method according to Embodiment 2 of the present invention. Furthermore, in the present Embodiment 2, configurations identical to those in Embodiment 1 are provided with the same symbols and the descriptions are omitted. 
     In this Embodiment 2, in the agent&#39;s server  4 , a script (index information)  21  written in Flash, etc. is combined with the banner image  10  sent from the advertiser&#39;s server  3  and is sent to each of the advertisement-providing servers  5   a  to  5   c  as advertisement information  9 ′. 
     This script  21  is a description program for indirectly indexing the identification information  11   a  to  11   c . In other words, the script  21  itself does not directly represent each item of the identification information  11   a  to  11   c , but it is a description program for representing the association with each item of the identification information  11   a  to  11   c.    
     For example, when the user U uses the user&#39;s computer  6  to access the advertisement-providing server  5   c  and views the advertisement-providing site  12   c , the posted information within this advertisement-providing site  12   c  is sent to the user&#39;s computer  6  and the content is displayed. At this time, the script  21  within the advertisement information  9 ′ on the advertisement-providing site  12   c  is executed, and the identification information  11   c  is required from the advertisement information management server  1  in order to cause the content to be displayed on the user&#39;s computer  6 . 
     When the script  21  is executed, the allocation numbers  14   a  to  14   c  of the advertisement-providing sites  12   a  to  12   c  on which the advertisement information  9 ′ including the script  21  is posted are also sent to the advertisement information management server  1 . Therefore, the advertisement information management server  1  can generate identification information  11   a  to  11   c  that are different for each of the advertisement-providing sites  12   a  to  12   c  and send it. 
     Therefore, each item of the advertisement information  9 ′ posted on each of the advertisement-providing sites  12   a  to  12   c  is combined information of the same banner image  10  and the script  21 , but each item of the advertisement information  9 ′ displayed on the user&#39;s computer  6  is a different item of the identification information  11   a  to  11   c.    
     Furthermore, the identification information  11   a  to  11   c  may be preliminarily generated and retained in the advertisement information management server  1  or may be generated in the advertisement information management server  1  each time the script  21  is executed. Moreover, for example, if the advertisement information management server  1  is configured to acquire the execution time of the script  21  (i.e., time the user U accesses the advertisement-providing server and views the advertisement-providing site), it is possible to change the identification information displayed on the same advertisement-providing site  12   a  in accordance with the execution time of the script  21 . It is therefore possible to statistically ascertain the advertisement effect of the advertisement-providing site  12   a  at different times. 
     According to this Embodiment 2, because it is not necessary to preliminarily allocate identification information to each advertisement-providing site, it is not necessary to preliminarily ensure a large amount of identification information in accordance with the number of advertisement-providing sites and it is possible to flexibly respond to increases and decreases in the number of advertisement-providing sites. 
     Embodiment 3 
       FIG. 10  is a schematic diagram illustrating the overall configuration of an advertisement information managing system S″ using the advertisement information managing method according to Embodiment 3 of the present invention. Furthermore, in Embodiment 3, configurations identical to those in Embodiment 1 are given the same symbols and the descriptions are omitted. 
     In this Embodiment 3, the identification information  11   a  to  11   c  are not displayed on each of the advertisement-providing sites  12   a  to  12   c  and only the banner image  10  sent from the agent&#39;s server  4  is posted. Processing has been performed on the banner image  10  for linking to the advertiser&#39;s server  3 , and when the user U clicks on the banner image  10  using the mouse, the advertiser&#39;s site  3   a  is displayed on the display screen of the user&#39;s computer  6 . 
     At that time, for example, when the banner image  10  posted on the advertisement-providing site  12   a  is clicked, the allocation number  14   a  of the advertisement-providing server  5   a  is sent to the advertiser&#39;s server  3  to be linked to. 
     A script  21 ′ is embedded within the advertiser&#39;s site  3   a , and this script  21 ′ is executed by access from the user&#39;s computer  6  and sends the allocation number  14   a  of the advertisement-providing server  5   a  to be linked from to the advertisement information management server  1 . 
     The advertisement information management server  1  generates the identification information  11   a  corresponding to the allocation number  14   a  of the advertisement-providing server  5   a  according to the execution of the script  21 ′ and sends it to the advertiser&#39;s server  3 . When the advertiser&#39;s server  3  acquires the identification information  11   a  from the advertisement information management server  1 , it displays the identification information  11   a  on the advertiser&#39;s site  3   a.    
     The script  21 ′ embedded within the advertiser&#39;s site  3   a  is capable of displaying each different item of the identification information  11   a  to  11   c  in accordance with the advertisement-providing sites  12   a  to  12   c  to be linked from. Therefore, it is possible to easily ascertain which of the advertisement-providing sites  12   a  to  12   c  the user U has viewed before making the call. 
     The preferred embodiments of the present invention have been described as the above, but the present invention is not limited to these, and various variations and modifications may be made without departing from the spirit and scope of the present invention. 
     For example, in Embodiments 1 and 2, configurations have been described in which the advertiser&#39;s site  3   a  is linked to the advertisement images  9   a  to  9   c  and the content of the advertiser&#39;s site  3   a  is displayed on the user&#39;s computer  6  by a click on the advertisement images  9   a  to  9   c , but this advertiser&#39;s site  3   a  is not an essential requirement. In other words, in Embodiments 1 and 2, the location to which the advertisement images  9   a  to  9   c  are linked may be a site other than the advertiser&#39;s site  3  (a site managed by someone other than the advertiser A), and cases in which the advertisement images  9   a  to  9   c  do not link to any of the sites do not deviate from the purpose of the present invention. 
     It is understood that in this case, the banner image  10  is not sent from the advertiser&#39;s site  3   a  to the agent&#39;s server  4 , but the banner image  10  may be sent from another of the above sites to the agent&#39;s server  4  or the banner image  10  may be generated within the agent&#39;s server  4 . 
     Moreover, in the above Embodiments 1 to 3, cases have been described in which the user&#39;s computer  6  to be connected to the Internet W and the user&#39;s phone  8  that is used to make a call have different configurations. However, for example, when using a cell phone provided with an Internet connection function and a phone call function or a computer also provided with a phone call function through an Internet phone function (a so-called “IP phone function”), it is possible to both view the advertisement-providing sites  12   a  to  12   c  and make a call to the advertiser&#39;s phone  7  through a single item of hardware (a cell phone or a computer with an IP phone function). 
     For example, when one of the advertisement-providing sites  12   a  to  12   c  or the advertiser&#39;s site  3   a  is displayed on the screen of a cell phone and one of the items of the identification information  11   a  to  11   c  is posted within the site, it is possible to make a call to the phone number indexed by the identification information  11   a  to  11   c  using the phone-to function of the cell phone by highlighting and selecting the identification information  11   a  to  11   c.    
     Similarly, when one of the advertisement-providing sites  12   a  to  12   c  or the advertiser&#39;s site  3   a  is displayed on the screen of a computer with an IP phone function and one of the items of the identification information  11   a  to  11   c  is posted within the site, it is possible to make a call to the phone number indexed by the identification information  11   a  to  11   c  using the IP phone function by selecting (clicking on) the identification information  11   a  to  11   c.    
     The advertisement information managing method according to an embodiment of the present invention is used in an advertisement information managing system for judging which advertisement information among a plurality of advertisement information a call that is made according to the advertisement information has been made according to, including a step for generating the plurality of identification information, and a step for cross-checking the plurality of identification information with input information in the call that is made according to one of the advertisement information among the plurality of the advertisement information generated in order to index the plurality of identification information respectively. 
     Because the plurality of identification information to be used to identify the advertisement information is generated automatically, it is not necessary to set different identification information for each advertisement information. Moreover, because the input information in the call is cross-checked with the identification information, when both match, it can be judged that the call has been made according to the advertisement information that indexes the identification information. Therefore, the advertisement effect for each advertisement information can be ascertained very easily without requiring much work. When the advertisement information is posted on different advertising media (e.g., different Internet sites), the advertisement effect can be easily ascertained for each Internet site. 
     As used herein, the advertisement information includes advertisement images (so-called banner advertisement) posted on Internet sites such as, for example, advertisement-providing sites. Moreover, the identification information and the input information may be, for example, a phone number, a part of the phone number or an identification number that a user inputs into the phone following the phone number. The advertisement image includes a moving image as well as a still image. For example, an image composed by movie data with the avi format, the mpeg2 format or the mpeg4 format, or animation data with the gif format or the flash format, etc. may be applied as the advertisement information. It is obvious that it is possible to apply voice data with the 3 the WMA format or the MP3 format, etc. as advertisement information as well as an image. 
     The situation of “advertisement information indexes identification information” includes the case in which the identification information is visually displayed within the advertisement image, and also includes the case in which the identification information is displayed in another window or a balloon frame or the like only when the mouse pointer is placed on the advertisement image on the display screen in spite that the identification information is not usually displayed within the advertisement image. Case in which the identification information is displayed when the advertisement image is clicked is also included. The case in which the identification information as voice data is included in advertisement information as voice data, or the case in which the voice data as the identification information being associated with the advertisement image sounds when the mouse pointer is placed on the advertisement image is applicable. 
     Even when the identification information is visually displayed, the identification information may be displayed in text and numbers or the like, or the identification information may be displayed using code information, such as a barcode or a two-dimensional barcode. For example, if phone number information is included as identification information within a QR code (a type of two-dimensional barcode) and the QR code is displayed within the advertisement image, a call may be easily made to the phone number with a cell phone that has a QR code-reading function and a phone-to function (a function for making a call to a displayed phone number through an easy operation, such as one click). 
     The advertisement information managing method may further include a step for generating the plurality of advertisement information by combining the plurality of identification information with basic advertisement information, a step for posting a plurality of the advertisement information on a plurality of first Internet sites, a step for receiving the call, a step for extracting the input information in the call, and a step for judging that the call has been made according to the advertisement information that indexes the identification information when the input information and the identification information match. 
     Because the plurality of items of advertisement information is generated automatically by combining the plurality of items of identification information with the basic advertisement information, the plurality of items of advertisement information combined by the basic advertisement information with the identification information can be generated without requiring much work. For example, if a loud advertisement image for gathering the attention of users is basic advertisement information, many items of advertisement information integrated by combining the loud advertisement image with each different item of identification information can be easily generated. Many items of advertisement information that can easily gather attention and ascertain each advertisement effect can be easily and collectively generated. 
     Because the advertisement information is automatically posted on the plurality of first Internet sites (e.g., advertisement-providing sites), the advertisement information that indexes different identification numbers can be posted on the plurality of first Internet sites without requiring much work. Therefore, it becomes easier to control the advertisement effect of each first Internet site on which the advertisement information has been posted. 
     Since the call that is made according to the advertisement information is received and the input information in the call is extracted, it becomes easy to cross-check the input information with the identification information. Consequently, it is possible to easily ascertain which advertisement information the call has been made according to and to easily ascertain the advertisement effect of each first Internet site on which the advertisement information has been posted. 
     Using this configuration, when a user accesses the first Internet site, the advertisement information including the identification information is displayed there. When a call is then made according to the identification information, the call is received and, according to the input information input by the user when making the call, it is ascertained which posted advertisement information among the plurality of first Internet sites the call has been made according to. Therefore, the user can easily ascertain the identification information (e.g., the phone number allocated for each advertiser and the advertisement information) by viewing the first Internet site, and can subconsciously and automatically notify which advertisement information the call has been made according to simply by inputting the identification information as the input information when making the call. Consequently, this contributes to ascertaining the advertisement effect of each item of the advertisement information. 
     The advertisement information managing method may also include a step for generating the plurality of advertisement information by combining a plurality of index information that indexes the plurality of identification information with basic advertisement information, a step for posting the plurality of advertisement information on a plurality of first Internet sites, a step for receiving the call, a step for extracting the input information in the call, and a step for judging that the call has been made according to the advertisement information that indexes the identification information when the input information and the identification information match. 
     Because the plurality of items of advertisement information is generated automatically by combining the plurality of items of index information that indexes the plurality of items of identification information with the basic advertisement information, advertisement information combined by the basic advertisement information with the index information can be generated without requiring much work. In addition, each item of the identification information can be indexed by the index information. For example, if a loud advertisement image for gathering the attention of users is basic advertisement information, many items of advertisement information integrated by combining the loud advertisement image with each different item of identification information can be easily generated. Advertisement information that can easily gather attention and be used to easily control the advertisement effect of each first Internet site can be easily and collectively generated. 
     As used herein, the index information may be, for example, a program (a subprogram, a macro program, a script, etc.) or an argument for indexing each different item of identification information. In addition, the identification information may be externally obtained by the index information. Different items of index information may be allocated to different items of identification information, or the same item of index information may index different items of identification information according to other conditions (e.g., access time, the number of visits, etc.). 
     Because the advertisement information is automatically posted on a plurality of first Internet sites, advertisement information that indexes different identification numbers can be posted on the plurality of first Internet sites respectively without requiring much work. Therefore, it becomes easier to control the advertisement effect of each first Internet site on which the advertisement information has been posted. 
     The call that is made according to the advertisement information is received and the input information in the call is extracted, makes it easy to cross-check the input information with the identification information. Consequently, it is possible to easily ascertain which advertisement information the call has been made according to and to easily ascertain the advertisement effect of each first Internet site on which the advertisement information has been posted. 
     Using this configuration, when a user accesses the first Internet site, the advertisement information including the identification information is displayed there. Because the index information indexes the identification information, the identification information is consequently displayed on the first Internet site. When a call is made according to the identification information, then the call is received, and according to the input information input by the user when making the call, it is ascertained which posted advertisement information among the plurality of first Internet sites the call has been made according to. Therefore, the user can easily ascertain the identification information (e.g., the phone number allocated for each advertiser and advertisement information) by viewing the first Internet site, and can subconsciously and automatically notify which advertisement information the call has been made according to simply by inputting the identification information as the input information when making the call. Consequently, this contributes to ascertaining the advertisement effect of each item of the advertisement information. 
     The advertisement information managing method may also include a step for posting a plurality of basic advertisement information on a plurality of first Internet sites, the basic advertisement information link to a second Internet site, a step for posting the advertisement information on the second Internet site, the advertising information being associated with the first Internet site when the basic advertisement information on the first Internet site is selected, a step for receiving the call, a step for extracting the input information in the call, and a step for judging that the call has been made according to advertisement information that indexes the identification information when the input information and the identification information match. 
     It is not necessary to post identification information or index information that indexes the identification information on the first Internet site, and it is possible to reduce the time required for posting the basic advertisement information because the posting of the basic advertisement information is only needed. For example, only a loud advertisement image for gathering the attention of users may be posted on the first Internet site as basic advertisement information. 
     Because the basic advertisement information links to a second Internet site (e.g., a site of the advertiser), when a user selects the basic advertisement information, the second Internet site is displayed. The advertisement information that indexes the identification information is posted on the second Internet site, so the user can make a call according to the identification information. Because the identification information is associated with the first Internet site, it can be different identification information for each of a plurality of first Internet sites. Therefore, according to the identification information, it is possible to ascertain which posted advertisement information among the plurality of first Internet sites has been selected and to easily ascertain the advertisement effect of each first Internet site on which the advertisement information has been posted. 
     The advertisement information managing system as another embodiment of the present invention judges which advertisement information among a plurality of advertisement information a call that is made according to the advertisement information has been made according to, including an identification information-generating part that generates a plurality of identification information, and an information-verifying part that cross-checks the plurality of identification information with input information in the call that is made according to one of the advertisement information among the plurality of advertisement information generated in order to index the plurality of identification information respectively. 
     Because the identification information-generating part automatically generates the plurality of items of identification information used to identify the advertisement information and the information-verifying part cross-checks the input information in the call with the identification information, it is possible to judge that the call has been made according to the advertisement information that indexes the identification information when the input information and the identification information match. Therefore, the advertisement effect of each item of advertisement information can be ascertained very easily without requiring much work. When the advertisement information is posted on different advertising media (e.g., different Internet sites), the advertisement effect can be easily ascertained for each of the Internet sites. 
     The call receiving method as still another embodiment of the present invention is used in an advertisement information managing system that judges which advertisement information among a plurality of advertisement information a call that is made according to the advertisement information has been made according to, including a step for receiving the call that is made according to one of the advertisement information among the plurality of advertisement information generated in order to index a plurality of identification information respectively, and a step for externally sending input information in the call in order to cross-check the input information with the plurality of identification information. 
     The call that is made according to the advertisement information is received and the input information in the received call is sent in order to be cross-checked with the plurality of items of identification information, and therefore, the input information can be easily cross-checked with the identification information at the destination. According to the verification results, it is possible to judge which advertisement information the call has been made according to, so the advertisement effect of each item of advertisement information can consequently be easily ascertained. 
     In a further embodiment of the present invention, the call receiving system receives a call in order to judge which advertisement information among a plurality of advertisement information a call that is made according to the advertisement information has been made according to, the call receiving system including a call receiving part for receiving the call that is made according to one of the advertisement information among the plurality of advertisement information generated in order to index a plurality of identification information respectively, and an information-sending part for externally sending input information in the call in order to cross-check the input information with the plurality of identification information. 
     The call receiving part receives the call that is made according to the advertisement information and the information-sending part sends the input information in the received call in order to cross-check the same with the plurality of items of identification information, and therefore, the input information can be easily cross-checked with the identification information at the destination. According to the verification results, it is possible to judge which advertisement information the call has been made according to, so the advertisement effect of each item of advertisement information can consequently be easily ascertained. 
     According to an embodiment of the present invention, a plurality of items of advertisement information can be provided automatically, it is possible to ascertain which advertisement information a call has been made according to without requiring much work, and the advertisement effect of each item of advertisement information can be easily ascertained. By posting the plurality of items of advertisement information on a plurality of first Internet sites, it is possible to easily ascertain which first Internet sites exert a high advertisement effect. 
     Moreover, by automatically updating the content of advertisement information posted on the first Internet site, it is possible to ascertain more detailed difference in the advertisement effect for each different time or day of the week, etc. 
     Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
