Request RPM is "0", why?

[Safe Kids Game Development]

Hello,

I have 3 game in android store. One of them is have an admob problem. Earning in that game is "0". I didn't figure it why. 

Here is the stats for that game;

Publish date = 30.01.2014

Impressions = 139

Request RPM = 0

Estimated earnings = 0

Fill rate = %100

Is anybody have an idea?

You only have 139 impressions. That is very few.

You only get paid if someone clicks on one of your ads. With only 139 impressions there is a good chance that no one clicked on any of ads. That is why the earnings are 0.
