Abstract:
A method of evaluating advertising expenditures includes establishing a first relationship between advertising position and bid price. A second relationship between estimated expenditure per time period and bid price is formed. An average advertising position for an entity is observed. A frequency of appearance for the entity is located. The average advertising position is mapped to a bid price using the first relationship. The bid price is mapped to an estimated expenditure per time period using the second relationship. The average expenditure is multiplied by the frequency of appearance to establish a per time period expenditure for the entity.

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims the benefit from U.S. Provisional Patent Application No. 60/828,370 filed Oct. 5, 2006 whose contents are incorporated herein for all purposes. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     This invention relates generally to data processing. More particularly, this invention relates to techniques for deriving Internet-based advertising expenditures for specific entities.  
         [0004]     2. Description of the Prior Art  
         [0005]     It is difficult to derive reasonable estimates characterizing how much an entity spends on marketing related to Internet-based searching. Of particular interest is not only the market size (e.g., how many entities spend at least $X per month on Google and Yahoo?), but also market distribution (e.g., of those that do spend at least $X per month, how many are at the low-end of that range) and how this market is changing. Getting a list of the particular entities and estimates of how much they are currently spending on search advertising facilitates various marketing activities.  
       SUMMARY OF THE INVENTION  
       [0006]     A method of evaluating advertising expenditures includes establishing a first relationship between advertising position and bid price. A second relationship between estimated expenditure per time period and bid price is formed. An average advertising position for an entity is observed. A frequency of appearance for the entity is located. The average advertising position is mapped to a bid price using the first relationship. The bid price is mapped to an estimated expenditure per time period using the second relationship. The average expenditure is multiplied by the frequency of appearance to establish a per time period expenditure for the entity.  
         [0007]     A computer readable storage medium, implementing the invention, comprises executable instructions to: query a search engine with a keyword to note an average position of an entity within the search engine results for the keyword; query a keyword estimate service of the search engine with a plurality of bid prices to establish a relationship between bid price and position; and map the average position against the relationship to obtain an estimated average daily spend to achieve that average position.  
         [0008]     An apparatus for deriving advertising expenditure of an entity comprises a lead-generation robot configured to multiply query a search engine using a designated keyword and store in memory a position of an entity appearing within pages resulting from each of said queries. The apparatus further includes a keyword estimate service query engine configured to query a keyword estimate service of an Internet search engine using a plurality of bid prices to obtain an estimated position associated with each bid price. Finally, the apparatus further includes an advertising expenditure calculator operative to average the position of the entity across all queries by the lead-generation robot for the keyword, establish a relationship between bid price and position using data obtained by the keyword estimate service engine, and determine an estimate of the advertising expenditure of the entity responsive to an association of the average position with the relationship

       DETAILED DESCRIPTION  
       [0018]      FIG. 1  illustrates a lead-generation robot  10  adapted to query both a search service  12  (e.g. google.com) and a keyword estimator  14  service of that search engine (e.g. Google&#39;s AdWords Keyword Tool) through a wide area network such as the Internet  16 . As will be explained further below, the lead-generation robot  10  gathers two sets of data through its multiple queries: (a) the average ad position of a third party responsive to multiple keyword queries of the search engine  12 , and (b) a relationship between bid price of the keyword and position through multiple bid queries of the keyword estimator  14 . From this data, the lead generation robot can determine an average spend of a third party for their particular advertising campaign.  
         [0019]      FIG. 2  illustrates a computer  10  configured in accordance with an embodiment of the invention. The computer  10  includes standard components, such as a central processing unit  18  and a set of input/output devices  20  connected via a bus  22 . The input/output components may include a keyboard, mouse, display, printer, and the like. Also connected to the bus  22  is a memory  24 .  
         [0020]     The memory  24  stores executable instructions to implement operations of the invention. In particular, the memory  24  stores an advertising expenditure analyzer  26 , which implements the operations discussed below.  
         [0021]      FIG. 3  illustrates the operation of the lead generation robot  10  of  FIG. 2 . In one embodiment of the invention, the lead-generation robot  10  uses keywords (e.g., aggregated across a variety of advertising campaigns) in block  28  and looks at the search results pages for these keywords from various search engines (e.g., Google and Yahoo) in block  30 . The robot notes the advertisers on those pages, e.g. using the displayed domain under each advertisement on the page, and the position of each of those ads on the page averaged over impressions. How often the advertiser appears for that keyword is also tracked. The characteristics of this information (e.g. factors) are arranged in Table 1, below:  
                                 TABLE 1                       Factors Gathered by Lead Generation Robot                                KEYWORD   ADVERTISER&#39;S   AVERAGE   FREQUENCY OF           DOMAIN   OBSERVED   APPEARANCE               POSITION   (FREQ)               (POS)                    
         [0022]      FIG. 4  illustrates a schematic of a Google® search results window  40  that may result from a typical search of the google.com search engine. The results window  40  includes a search filed  42  into which a user would input search terms, e.g. “keywords.” Searches would be conducted using the search engines proprietary systems and result in a list of the most relevant items displayed in a search results field  44  in order of relevance. To generate income, such search services also offer commercial organizations the opportunity to appear on these search results pages in a sponsored links portion  46  of the search results window  40 . A common method for such search engines to trigger these paid listings is through keyword triggers—that is, third parties would bid for the right to appear on search result pages when certain words are entered in the search field  42 . The order of such listings within the sponsored links field  46  is often determined by the amount of money paid by the party to be listed. The more money spent, the higher and more frequent the listing. Search engines such as google.com will often use algorithms to determine when such sponsors are listed, how often, and how high on the list.  
         [0023]      FIGS. 5A, 5B , and  5 C illustrate examples of three queries of the Google® search engine for the same keyword. In this instance, the word “cameras” is input by lead generation robot  10  in the search field of the google.com web page and the sponsored links in field  46  observed.  FIG. 5A  illustrates the result of the first query by lead generation robot  10 .  FIG. 5B  illustrates the result of the second query, and  FIG. 5C  illustrates the result of the third query. Table 2 below lists the first five sponsors observed from the three queries:  
                                 TABLE 2                           Sponsor Position in Keyword Search for “cameras”            POSI-                   TION   QUERY #1   QUERY #2   QUERY #3               1   Buy.com   Sears   Kodak       2   Dell   Circuit City   Circuit City       3   HP   Buy.com   Buy.com       4   BuyersEdge.com   PCConnection.com   PCConnection.com       5   Shopping.AOL.com   BuyersEdge.com   BuyersEdge.com                    
         [0024]     One notes that the same query can result in a very different list of sponsors. The top listed entity in each of the three queries is different: Buy.com, Sears, and Kodak. Furthermore, patterns of appearance emerge with more and more queries. For instance, Buy.com appears in all queries: in position #1 in the first query, and in position #3 in the second and third queries. BuyersEdge.com also appears in all queries, but at a lower position: in position #4 in the first query, and in position #5 in the second and third queries. The frequency of appearance for both Buy.com and BuyersEdge.com is thus high. Sears and Kodak, thought they appear at the top of one of the queries, do not appear in the top five list in the other queries. Their frequency of appearance is thus low.  
         [0025]     A keyword estimate service (e.g., the Google service) is supplied with a keyword and a bid price in block  32 . In return, the service supplies an estimated expenditure per time period (e.g., spend/day) as well as an average position in which an ad would appear. Alternate versions of the service might report a bid range for clicks per day and costs per click (as well as average position) from which the daily spend can be calculated. If one applies several different bids for a keyword, one can estimate a bid for any position using a method similar to linear interpolation in block  34 .  
                                     TABLE 3                       Factors Gathered from Keyword Estimate Service                                    KEYWORD   BID   ESTIMATED   ESTIMATED               PRICE   POSITION   DAILY SPEND                      
 
         [0026]     By querying for several bid prices, one can interpolate the entire curve of Position to Bid price, as well as the curve of Bid price to Daily spend. With these two curves, one can, for each Domain, use POS to estimate Bid price, then use that Bid price to estimate Daily Spend (multiply the result by frequency).  
         [0027]     By continuously updating this data and adding keywords to a database, one can improve the accuracy of data and see trends. In addition, one can identify entities that are good targets for marketing initiatives.  
         [0028]     Consider the following example in which one is interested in the keyword “discount stuff.” The keyword estimate service may be queried with several bids:  
                                                           TABLE 4                           Sample Data from Keyword Estimate Service                    BID   ESTIMATED   ESTIMATED           KEYWORD   PRICE   POSITION   DAILY SPEND                            “discount   0.50   8   25           stuff”   1.00   4.5   60               2.00   2.2   100                      
 
         [0029]     This information can be plotted as shown in  FIG. 6  and  FIG. 7 . A robot then generates results from crawling “discount stuff”:  
                                 TABLE 5                           Observed POS/FREQ for acme.com using       “discount stuff” keyword                    AVERAGE                   OBSERVED   FREQUENCY OF           ADVERTISER&#39;S   POSITION   APPEARANCE       KEYWORD   DOMAIN   (POS)   (FREQ)               “discount   www.acme.com   3.2   75%       stuff”                  
 
         [0030]     Using the first curve of  FIG. 6 , an average position of 3.2 means a bid price of about 1.57. Using the second curve of  FIG. 7 , a bid price of 1.57 means an average daily spend of about 83. Using the frequency of 75%, one estimates that acme.com is spending about 62.25 on ads for the “discount stuff” keyword per day.  
         [0031]     It is useful to keep track of the observed average position and frequency for each advertising network. An appropriate estimate service should be used for each advertising network. If only one estimate service is being used, one may assume the same market conditions and bid price curves for a different service.
