Hi one of my sites has heaps of traffic. And today i fixed it up through site studio. And i view my each page of my site in site studio a few times, so in total about 100 impressions on my own pages. But since its in site studio this doesn't count. When i saw 150 impressions. 0ecpm nothing made from it. I thought it was me. So i sent google adsense a message. But i think ecpm is just 0 is this possible?
Yes, if all the 150 impressions were from CPC based ads and there were no clicks, the eCPM would be 0.
