I found an Adsense ad displaying on one of my sites. When I go to the url in the ad -- www.tunu.com - it claims to be a search engine - but all it seems to do is display adsense ads. It does not find too much when searching and what it does find looks like affiliate links. Does all this violate Google TOS?
there are links to search results under adsense ads (for the keywords i tried). so, i don't see anything violating the TOS on that site. perhaps your particular search did not return any real results and all you saw were adsense ads on the search results page?
