I wrote a quick and dirty article about how to test pay per click search engines.
If you've been thinking about trying pay per click traffic, but you were worried about fraud, or how to figure out if it's worth your while, my quick guide might help.
The article is about how to test pay per click search engines and where to spend your pay per click ad budget. It is NOT about how to find pay per click search engines to advertise on in the first place. That information is easily found by doing a Google search.
(i.e., I don't want to start yet another thread about "which PPC engines accept poker ads?")
