PeakClick is a new ppc provider that pays 70% of the revenue. Cost per click rates are mediocre but much better than searchfeed, miva, 7search and the likes. For example casino keywords go up to $1.3 and mortgage keywords up to $1.

They give you an xml feed with ads that you can parse as you want and display it on your pages. If you are scraping search results, you can replace the links to the sites, with links that pay you when clicked. This way you maximise the chances of a visitor to make you money.
