Hi Let Me If i am only one or u guys also noticed that same clicks give u more money in first week after that Rates go down.
I've noticed that too. Yesterday I had 202 clicks, the most I've had since joining Adsense. Yet I earned less than I made the first couple of days. Since then my earnings have diminished with more traffic and higher CTR. Go figure.
It would make sense for it to change (up or down) as time goes on because Google is able to evaluate the value to the advertiser that your users are bringing to them.
How do they do this? What I mean is, how do they know if the surfer purchased anything or not? Darren.
