[UA→GA4] Engagement goals [Legacy]

In Universal Analytics you can configure goals based on Average Session Duration and Pages/Screens per session. These are often referred to as engagement goals since they signal an overall threshold of engagement rather than the completion of a specific action. This article describes how you can measure these activities in Google Analytics 4 (GA4) properties.

Replicate Pages/Screens per session goals as a GA4 audience

A Pages/Screens per session goal triggers when a user loads the specified number of pages or screens within a session. For example, in Universal Analytics, you can configure an engagement goal of more than 2 pages per session as follows:

You can use the GA4 audience builder to create groups of users who meet a similar goal:

1. Create a new custom GA4 audience.
2. Name this audience the same as your Universal Analytics Pages per session goal.
3. Set the Membership duration to “Maximum limit”.
   Note: You can create up to 100 audiences (400 for Analytics 360 properties).
4. Set the Scope to “Within the same session”.
5. Under Include Users when:
   • Add a condition where event_name = page_view and the event_count parameter > 2.
   • Add an OR clause.
   • Add a condition where event_name = screen_view and the event_count parameter > 2.
     Note: if your property doesn't include an app data stream, you won't see (or need) the screen_view event. Likewise, if your property doesn't include a web data stream, you won't see (or need) the page_view event.
6. Create an audience trigger and use the same name as the Universal Analytics Pages per session goal.
   Note: You can create up to 20 audience trigger events per property
7. Click Save.
8. Mark the audience trigger event you created in step 6 as a key event.

User engagement

GA4 automatically collects a number of engagement dimensions and metrics. These appear in several built-in reports, and you can add them to explorations. Learn more about engagement metrics in [GA4] Engagement metrics.

In particular, GA4 records a user_engagement event for sessions that either:

• last more than 10 seconds, or
• contain a key event, or
• have two (or more) pageviews.

You can use user_engagement as a proxy for Page/Screens per visit and Average Session Duration goals in Universal Analytics.
