I had a click for $10.11 once. Other then that my avg click ranges between $.40-$.50 If you want more per click pick the niche where the money is
You guys, what niches are you picking with these 3 cent clicks??? And are your websites well set up for adsense? As in, do you have fresh original content with relevant keywords in the articles? If someone searches for "get into nursing school" and comes to my site they find a ton of articles about how to get into nursing school. That's what I mean by relevant. You need to make the most out of your time and effort - if you are going to set up a website to make adsense money, do some research and find the high paying keywords, and then make sure your website fits in with google's adsense policies so you make decent money off of any clicks you get.
maybe the possible of a new country based ip address command higher ppc than regular users clicks of a exisiting country
