Potential Admob revenue

Hi,
I have a mobile app rining admob but I find my revenue very small compared to Adsense or Adsense for YouTube...

In fact I have 1830 impressions, 4000 requests, 96% of match rate eCPM of 2.7$ but only 5$ in revenue.... Is this normal ? (I'm new with Admob maybe this is better then other people revenues....)

With only around 1.8k impressions revenue will naturally be limited the volume is still too small to judge overall performance.

you had 3840 matched ads but only 1830 showed (48% show rate), this is often normal for full screen ads. only fix it if you are calling show() before the ad finishes loading, and don't add more ads to force it up, that just annoys users and they leave. other than this, all seems fine
