pay-per-click search engines
 

I know of most of the PPC affiliate programs but I wanted to know which makes you the most money? I am looking for the kind that pays you a certian % of the BID price when the search results show up on their page or even if I have to display the results on my page. I have tried coolwebsearch.com but I want to see if there are any better ones that do better. I would appreciate any feedback.

Thanks!
