I know there are quite a few out there that offer pay per click or CPM........ Google - adsense Yahoo clicksor adbrite chitika bidvertisor The only one I use is clicksor, it seems easy to use, Any1 want to add other sites they know or explain what site they prefer
Clicksor sucks, you get low-paying highly untargeted ads. You also get those GIANT annoying popunders which make visitors angry.
