Heh, what I found out!
Ok, i started the site (link in my signature) a few days ago.
I recently put the highest paying Google keywords on it, just to help webmasters.
Then I started noticing my Adsense ads where adjusting to them.
In short, if you have an SEO-related site include a top paying keyword list on your site, my current CPM is $10 for today, and $18 for yesterday.
Not bad, huh?
Hope this helps some people!
