Key event measurement can help you to understand if user interactions
effectively lead to valuable customer activity within your mobile app, such as
in-app purchases, subscriptions, and sign-ups.
Google Analytics 4 properties enable unified measurement of user interactions
and events across your website and mobile app. Google Analytics 4 collects many
events by default, and some events are automatically marked as key events. App
data streams within Google Analytics 4 properties utilize the Firebase SDK to
send events. Learn more about events.
Additionally, you can enable or turn off other automatically collected events,
or mark custom events as key events as well.
You can register an event as a key event either before or after the event is
sent.
To register an event before it is sent:
In Analytics, navigate to the reports for your Google Analytics 4 property.
Click Key events.
Click New key event.
Enter the name of the event you want to identify as a key event. Note:
Make sure the event name you enter is exactly the same as the event that you
are sending.
Click Save.
If you’ve already sent the event previously and want to mark it as a key event:
In Analytics, navigate to the reports for your Google Analytics 4 property.
Click All events.
In the row for the event, turn on the switch in the Mark as key event
column.
