In March 2004, Yahoo! launched a paid inclusion program whereby commercial websites were guaranteed listings on the Yahoo! search engine after payment. This scheme was lucrative, but proved unpopular both with website marketers (who were reluctant to pay), and the public (who were unhappy about the paid-for listings being indistinguishable from other search results). As of October 2006, Paid Inclusion ceased to guarantee any commercial listing and only helped the paid inclusion customers, by crawling their site more often and by providing some statistics on the searches that led to the page and some additional smart links (provided by customers as feeds) below the actual url.
