Ad eCPM Chart
Available in Charts v3 only. This chart isn't listed when Charts v3 isn't enabled.
The Ad eCPM (effective Cost Per Mille) chart shows how much you earn for every 1,000 ad impressions. This metric helps you compare monetization efficiency across different time periods, countries, or platforms regardless of total impression volume.
Measures
Revenue: The total amount earned from ads during the period.
Impressions: The total number of times ads were displayed to users.
Impressions in thousands: The total number of impressions divided by 1,000, used to calculate eCPM.
Calculations
eCPM: The average revenue earned per 1,000 ad impressions, calculated as (Revenue ÷ Impressions) × 1,000. Higher eCPM indicates more effective monetization.
Available settings
- Filters: Yes
- Segments: Yes
Ad dimensions
Ad charts can be filtered and segmented by ad-specific dimensions like Network Name, Mediator Name, Ad Format, Ad Placement, and Ad Unit. See Ad Impressions for details.
How to use Ad eCPM in your business
eCPM is essential for understanding monetization efficiency independent of scale:
- Compare eCPM across countries to identify high-value markets worth targeting
- Track eCPM trends to see if monetization efficiency is improving over time
- Segment by platform to optimize ad strategies for iOS vs Android
- Use eCPM to evaluate the impact of ad placement changes or new ad formats
- A stable or growing eCPM while impressions increase indicates healthy ad monetization
- Compare eCPM across app versions to see if updates affect monetization
Calculation
For each period, we calculate:
- Total ad revenue
- Total ad impressions
- Impressions in thousands = Impressions ÷ 1,000
- eCPM = Revenue ÷ Impressions in thousands
eCPM is expressed in your display currency with two decimal places of precision.
Example
If you earned $500 from 100,000 ad impressions:
- Impressions in thousands = 100,000 ÷ 1,000 = 100
- eCPM = $500 ÷ 100 = $5.00
This means you earned $5 for every 1,000 ad impressions.
