Can any body tell me whats wrong. I increased from 3000 impressions to 4000 impressions per day and my CTR and eCPM got decreased and also my earnings got decreased
I think google has prepared this payment rate with some tricks. As example, if 100 result is B, when 200 result is not 2B. Result will be below 2B.. Some thing like that...
It depends how you managed to increase your page impressions, was it because you added you ads to more site/pages etc or the number of visitors to your site increased? I suspect the impressions increased because you placed more ads on your site which does not significantly effect the number of clicks. And because the clicks are about the same the CTR and eCPM reduced because of how its calculated.
