I would like to know that from where can i see that how much have i earned from CPm till now as i am not able to figure out what are my earning from Google Adsense CPM.
I think, CPM doesn't represent your earnings - rather, it's calculated by dividing your earnings by number of page impressions, then multiplying by 1000. Like this Example, if you earned $0.15 from 25 page impressions, then your eCPM would equal ($0.15/25)*1000, or $6.00. If you earned $180 from 45,000 impressions, your effective CPM would equal ($180/45,000)*1000, or $4.00.
CPM does...You can find it at your advances reports, when you target reporsts as contexual and Site... I see as 3000-4000 site targetted impressions and 3-5$ with 0 clicks ....so yes, CPM
