I have a vague understanding of what smartpricing is, but can a guru give me a clearer meaning? Is it on per site or per account? Has it been confirmed by google? How drastic is it? Are myspace sites affected by it or is it just that myspace keywords are thaat bad. I think they are. I have a site that gets around 3000 impressions a day and makes 3.00 a day. I see other sites that get half of that and make the same. Granted, they can posibly have a higher CTR and thus equal clicks, but this seems unlikely. In anycase, this is a poor example. So.... Answer my quesiton
From my experience with adsense, it seems that when your site gets popular and gets many visitors, google will significally decrease the payment you get for each click. I dont know why, but its happend to all my sites so far. I had sites getting 50 cent to 1 dollar a click as the avarge, but now its all dropped down to 2 - 10 cents. The average now is about 5 cents pfffff. I'm quite annoyed by this strategy.
