What are advantage and disadvantage of eCPM in online advertising?
There is no advantage or disadvantage to eCPM or effective cost per impression. Rather, eCPM is an important way to compare your website’s revenue across different channels and advertising programs. eCPM is a metric that tells you how much you earn from your page impressions. It is calculated by dividing total earnings by the number of impressions in thousands. For example, by using Google Adsense you earned $1,000 from 100,000 impressions, then to calculate eCPM: $1,000/(100,000/1,000) = $10 Then with Burst Network for example, with 100,000 impressions you earned only $250 then eCPM is: $250/(100,000/1,000) = $2.
