The best way to advertise on the Internet is to create your own web site and then submit information about your site to as many suitable search engines, directories and portals as possible. Search engines are programs on the Internet that allow users to search for files and information. Some search engines ask you to fill out forms describing your site and listing suitable categories whereas others use automatic indexing systems.
Search engines regularly collect information about new web sites.
A programme called a robot or spider or crawler checks the pages of sites it finds. With the help of another programme it then creates a catalogue describing all the pages it finds, listing each page name with various appropriate keywords. When surfers ask the search engine for a document they enter keywords. The search engine compares these keywords with those in its catalogue and then sends the user a list of suitable matching links. Directories are like online yellow pages.
