Abstract: An application program interface (API), enables web development tools to interact directly with a hyperlink database subsystem. Tool developers use this API to design functionality that enables affiliates to log on to the hyperlink database system and generate merchant links. In response to requests from vendors' tools, the invention API uses the XML format to deliver requested hyperlink generation information. The requests are encrypted for users' privacy. The returned hyperlink generation information includes lists of merchants, lists of hyperlinks to the merchants web sites, the HTML code supporting the hyperlinks, and graphics for the links. Users implement hyperlinks by selecting among the choices returned in the response to the request and graphically placing (i.e., by drag and drop interaction) the resulting hyperlinks on subject web pages in a simple, error-free manner.

Abstract: Computer network method and apparatus provides targeting of appropriate audience based on psychographic or behavioral profiles of end users. The psychographic profile is formed by recording computer activity and viewing habits of the end user. Content of categories of interest and display format in each category are revealed by the psychographic profile, based on user viewing of agate information. Using the profile (with or without additional user demographics), advertisements are displayed to appropriately selected users. Based on regression analysis of recorded responses of a first set of users viewing the advertisements, the target user profile is refined. Viewing by and regression analysis of recorded responses of subsequent sets of users continually auto-targets and customizes ads for the optimal end user audience.
