i cant understand completely eCPM what is this if my site impression going to up and up then eCPM are also up or not and how can i get high cpc ? Thanks in advance for your suggestion thanks again.
eCPM is simply how much money you get paid per 1,000 ad impressions. eCPM is dependent on CPC and CTR. The more traffic you get, the eCPM should stay stable, or perhaps go down a little since the more traffic you have the more difficult it is to keep CPC and CTR high.. But usually eCPM should not change too much with increased traffic.
cpc depends on topic of your page and also country origin of traffic. Western traffic is better for most topics if not all. wallpapers topics has low cpc everywhere.
