When writing revenue sharing articles and researching keywords, CPC - the metric that stands for "cost per click" and, when using the Google AdWords keyword tool, represents the estimated bid amounts advertisers can expect to pay for keywords - may not be as important as SEO experts will tell you. In my experience, CPC never jives with actual Google AdSense earnings, even after taking into account the 68% publishers get after the split, and I don't give it more than a fleeting glance when I do keyword research.
