Abstract: A system and method for electronic advertising using a search engine include providing an incentive to users of the search engine to become members, collecting demographic information from users while registering to become a member, and associating the demographic information with an advertisement when a user responds to the advertisement. The method may also include providing advertisers with statistical information relative to user demographics for users who responded to a particular advertisement. In one embodiment, the member demographics may be used by advertisers to target particular advertising campaigns to members based on member demographic information. Likewise, demographic information entered by advertisers may be used by the administrator or other advertisers to target advertising information to those advertisers using the search engine.
