What's the problem with admob and my app?

Hi, I’m new here!

I have a problem with one of my apps and I don’t know what is wrong. In the picture you can see 3 of my apps and her results, the first application before had a CTR of 1-1.4% and now is about 0,20%. The app has no changes from near a year, the ads are the same but the CTR its to low, 17000 impressions and only 31 clics…

Only happens in this app… the others maintain the CTR more or less.

Any suggestions or idea? I don’t know what to do…

Thanks.

Go to Adsense and compare your ad types shown in this timeframe. Rich Media and Placement Ads have the highest CTR, but the CPC is a bit lower. From what I see your RPM didn’t decrease as much as you CTR, so the possibility that your app might not performing good for some advertisers came to mind.

In Admob I don’t know where to find this… I don’t stop wondering why suddenly the people stops clicking in the ads only in one of my apps…
