AdSense eCPM (effective cost per thousand impressions): Explained

effective Cost for Per thousand iMpressions, sounds pretty technical but in simple words, it is the amount of revenue one can expect to earn from AdSense, per every 1000 impressions shown on one's site.
eCPM could be helpful in many ways to a site owner or a publisher. it is a fine example of how your site and advertisements on it are performing. ( If you were looking for eCPM on your AdSense control panel, you will not find it. But what you will find is the RPM, Revenue Per thousand iMpressions, which means the same as eCPM.)
On the control panel, one could check performance data, broken down in periods and you will see the RPM based on those period. day, yesterday, last 7 days, last 30 days and so on. Longer the period, more accurate the data will.be.
Now that we know what it is, the obvious next question is "what are the factors that govern the eCPM? and another sure fire question, "what could one do to improve and earn a high eCPM?"
But the good people of AdSense have come to our aid and have kicked off a two part video series to explain and inform all about AdSense eCPM.
The first part of the series, AdSense Manager, Matthew Carpenter Arevalo introduce us to the basics of how eCPM is calculated and explain how to analyze the causes behind any changes in your eCPM.


There is more information on eCPM at the help center as well.
