About change history
Change history can help you troubleshoot anomalies in your account. For example, if you noticed a drop in revenue on a certain date, you can search for changes made to your account around that date to determine what may have caused the drop.
To view your account’s change history:
- Sign in to your AdMob account at https://admob.google.com.
- Click Change history in the sidebar.
Change details
Change history includes app-level and account-level changes. For all changes, the following details are available:
- The date and time the change was made.
- The item that changed. If the item is hyperlinked, you can click to view where the change was made. For example, if you changed the ad type on an ad unit, the link will take you to the ad unit that was changed.
- The type of change. For example, “Added app."
- The user who made the change. Learn more about the user column.

AdMob is constantly working on improving change history. This means that you can expect new changes to be added to change history over time. Note that new changes only affect events that occur after they've been added to change history - they're not retroactive. For example, if a new change is added on March 31, 2022, you won't find instances of that change in your account prior to March 31, 2022.
User column
The user column lets you know which one of the following users made the change:
- The email of the user who made the change.
Note: If you don't have administrator permissions, you'll see "Authorized user".
- User's email at [MCM partner company]. This will only appear if you're in an MCM agreement.
- Google. This means that an AdMob representative made the change.
