I know what eCPM means, but I don't know how this effects final earnings, well if I'm honest, I don't know how adsense earnings are calculated at all.. I saw somewhere that it's a secret how they do it. Is there someone that can explain or tell me how to calculate earnings..

I made a formula to caculate adsense earnings, but who knows if thats anything close to how it really works

=((B2*0,17)*(C2*0,5))*0,03

It's and excel formula, so B2 is CPC, 0.17 is around 17% what I think google pays you per click, C2 is numnber of estimated searches for a specific keyword, 0,5 is 50% click to your site on SERP if you are #1, and 0,03 is 3% CRT on your site ..

So for an example:

CPC is \$2
Estimated seraches per month = 10.000

=((2*0,17)*(10000*0,5))*0,03 = \$51 .. what do you think guys?

Which tool are you using to get your Estimated Search numbers?

I could find a bunch of keywords for which I rank #1, find their Estimated Search volumes in that tool, and look up my AdSense earnings from each keyword in the last 30 days. I could then publish the average numbers.

Then, I could do the same for some of my #2 rankings and my #3 rankings.

What do you think?

eCPM does not "affect" your earnings at all. It's simply another way of representing your earnings. It tells you how much money you are (or would be) making per thousand page impressions. Here are some examples:

3000 page impressions, \$30 earnings => eCPM = \$10
2876 page impressions, \$17.48 earnings => eCPM = \$6.08
132 page impressions, \$3.29 earnings => eCPM = \$24.92

Basically, eCPM = earnings / (impressions/1000)

Or equivalently, eCPM = 1000 × earnings/impressions

eCPM is a useful way to quickly compare the earning power of different websites, or channels, etc.

Hope this helps.
