Many of us have wasted thousands of dollars on PPC search engines with poor or non existant traffic. The clicks garnered from these are not real visitors but are generated by cgi scripts or via third world sweat shops. There are numerous posts and news articles about this here at CAP. You can do a search or just do some casual study down in our PPC forums.
Kanoodle, ePilot, Xuppa, Search123, Pageseaker, Searchfeed and a host of others provide essentially zero ROI for purchasers.
Lycos’ PPC traffic is administered by Findwhat . While Findwhat still accepts Online Gambling Keywords, Lycos does not. I have had accounts with both for years as have most seasoned webmasters.
Findhwhat is the third largest paid search provider online While their traffic does not produce sales as well as Overture or Google Ad Words they are certainly far more worthwhile then 99% of the others.
