Method and apparatus for implementing search engine with cost per action revenue model

摘要

The inventive technology enables the search engine operator to charge the advertisers who place their links on the search engine only if the user uses the search results to visit the advertiser's web portal(s) and generates revenue for the advertiser. This concept is especially attractive to the advertisers because it eliminates the risk, which the advertisers face in conventional search engines, when they are changed by the search engine per user click irrespectively of whether the user's visit resulted in advertiser's revenue.
