2. Go to Admob reporting to monitor your revenues. You need the Reports tab. There you will see total income and how much each application earned during the period of your choice.
3. We look at two key indicators:
- Estimated earnings — a preliminary amount, which is an estimate of how much the application has earned. This amount is an estimate that is subject to change when your earnings are verified for accuracy at the end of every month.
- Impression RPM (the same as CPM) — the price for 1000 impressions of the ad unit. Impression RPM doesn't represent how much an ad actually earned; rather, it's calculated by dividing estimated earnings by the number of impressions received, then multiplying by 1000.
