Learn how to continue collecting metrics in AdMob.
This article provides an overview of the user metrics card, which offers insights into aggregated user behavior within a chosen app. Estimated revenue data may be obtained from multiple sources. The line graph beside each metric gives you a snapshot of how the value has changed over time.
The user metrics card can be found in your app overview dashboards.
Metrics found in this card
- Sessions / AU: The average number of sessions per active user (AU). A session is counted when the app is in the foreground of the device. The session ends when the app is moved to the background or after 30 minutes of user inactivity.
- Avg. session duration: Total engagement over the selected date range divided by the number of sessions.
- Ad exposure / session: Total ad exposure time over the selected date range divided by the total engagement over the selected date range.
- Active users (AU): The number of unique users who have opened the app. Active users is sometimes known as DAU (daily active users) when aggregated by date.

Troubleshooting user metrics
If you notice all zeroes in your user metrics card:
- Make sure you’re using the Firebase SDK for Google Analytics (Android, iOS) and link your app to Firebase.
- Ensure that you’ve implemented your app correctly according to the instructions in the Google Developers Get Started guide (Android, iOS).
- If you selected the option to link to an existing project and create a new app, you’ll lose historical user metrics data for that app. Learn more about linking your apps to Firebase.
