What Is GA4? Event-Based Measurement, and Why It Feels Different

In plain English

The previous version organised everything around sessions and pageviews. GA4 organises everything around events, so a pageview, a click and a purchase are the same kind of thing with different names.

That is why familiar reports vanished and metrics changed definition. Bounce rate, in particular, now means the inverse of engagement rather than a single-page visit.

What to know

Everything is an event

Views, clicks, purchases, scrolls.

Key events replace goals

Marked as business outcomes.

Engagement replaces bounce

Bounce is now its inverse.

Explorations for depth

Standard reports are shallower by design.

Why it matters

The event model is more flexible and less immediately legible. Getting value from GA4 usually means configuring key events properly and learning explorations rather than expecting the old reports back.

Common mistakes

×Comparing GA4 figures to the previous version.

×No key events configured, so nothing is measured as an outcome.

×Expecting the old report layout.

×Ignoring explorations, where most of the analysis lives.
