I run a freebies site for adsense (as you would probably know the adds are really easy to convert). My dilemma is my minimum CPC i can get is 0.15 cents, which means no profit at all. Im trying to get into some 0.01 cent keywords. but there literally seem to be none at all. Also how many of you are using adwords to promote adsense? I get the genuine consensus adwords is for ebay and CJ? Cheers fellas. I know a lot on adsense but not adwords. I will do my best to help you with what i know with adsense.
if you have site for free stuff why don't you try freebie offers from Copeac and other CPA networks? They convert well and $0.15/click can make you profit
