What Is an Active User? The Default Metric in GA4
DICTIONARY · ANALYTICS

What Is an Active User?

An active user is a user who meets Google's criteria for active engagement.

In plain English

GA4 reports active users by default rather than total users. The criteria involve having an engaged session or triggering certain events, rather than merely loading a page.

This is one reason GA4 user counts look lower than the previous version's. It is a different definition, not a traffic decline.

What to know

The GA4 default
Reported in place of total users.
Requires engagement
Not just a page load.
Lower than total users
By definition.
Not comparable historically
To the previous Analytics version.

Why it matters

A GA4 migration that appears to show a traffic drop is usually showing active users against previous total users. Knowing which metric is on screen prevents a false alarm.

Common mistakes

×Comparing active users to previous total users.
×Assuming a drop at migration was real.
×Not knowing which user metric a report shows.
×Reporting active users without stating the definition.

FAQs
