Hello,I've recently joined adsense with google and I was wondering does the sites PageRank have anything to do with the CPC? If I gain a PR point does that require my CPC to go up? how does it work?ThanksPR has absolutely nothing to do with the earnings per click.the cost per click is determined by how much people big over your target terms.So if you really wanted to raise your cpc for Adsense you could go through Adwords and see what terms are the most competitive. I'm guessing something along the line of houses or cars. Then optimize your site to get those ads on your page and have people click on them.
