eCPM stands for 'effective CPM' and is an estimate of the revenue you will achieve in 1000 page views based on your earnings thus far. CPM is your actual earnings per 1000 page views. As for eCPC, who knows?
eCPC, same thing. Effective cost per click. Usually used when you are being paid by CPM or CPL or CPA. If you are, feel free to contact me to increase your earnings Thanks
No it's not!! ECPC is Enhanced Cost Per Click, not "effective". It's a bidding feature in AdWords where you let AdWords increase your max CPC by up to 30% on ads that it thinks are most likely to convert. Likewise it decreases bids on ads that it thinks are unlikely to convert.
