what is rpm in adsence

Page RPM. Page revenue per thousand impressions (RPM) is calculated by dividing your estimated earnings by the number of page views you received, then multiplying by 1000.

New Adsense interface rolled out for all users recently. It looks promising and useful. I like it. This is the first time I’m seeing a different a interface after three years. It’s with more details and easy to understand format with graphs. There are some new factors make confusion in first screen. What is RPM in new Google Adsense interface? Its very simple, “Revenue Per Mile”.

It means, Revenue Per 1000 impressions. So what the difference between eCPM and RPM in adsense?. There is a difference. eCPM is calculated by Page impressions whereas RPM by ad impressions.

example

You have 3 ad blocks on each page and one day you earned 20$ with 10000 Page impressions.

So, average eCPM is = 2$

(Earnings/Page Impressions) * 1000 =  (20$/10000)*1000

What’s the RPM in this case?

New interface will show 30000 impressions, because each 10000 pages got 3 ad blocks.

So average RPM is = 0.67$

(Earnings/Ad Impressions)*1000 = (20$/30000)*1000

Need some prove?

Here is the stats from new interface for today.
