What is eCpm Filling Speed ​​rpm

Question

I created ads for my application using admob-sdk. I get income, but I don’t know what eCpm, fillrate, rpm I searched on the Internet but cannot find the right solution for this question.

Answer 1

These are different ad network metrics that can help you determine how effectively your app displays ads.

Ecpm = Profit Per Thousand Requests

Fill rate = percentage of your requests that received ads (sometimes there is no ad to show)

Rpm = profit per thousand requests (almost the same as ecpm)
