Any Web site that an advertiser would like to list with Yahoo! Search Marketing must be the advertiser's own site, and we must be able to verify such ownership. This also means that all search terms requested by an advertiser must refer directly to the content of their own site. URLs that automatically redirect users to another Web site are not acceptable. In addition, Web sites may not replicate the exact appearance of another site - particularly if it might lead users to believe they are actually on the replicated site.
What does not qualify as the advertiser's “own site”?
