What is eCPM?

ECPM stands short for Effective Cost per Mille. This metric shows developers how much ad revenue they generate per 1000 ad impressions in their app. 

How to calculate eCPM?

To calculate eCPM, divide your app’s total ad revenue by the number of total ad impressions, and multiply by 1000.

Why is eCPM important for developers?

ECPM helps developers understand how effective and valuable are the ads served in their apps. It’s important to note that this metric varies by different factors such as: 

  • Ad format
  • Ad network
  • Location
  • OS (iOS, Android) 

By analyzing this metric based on these variables, app developers can identify the most valuable revenue sources and optimize their ad placements.
