Both are "counting something," but they mean different things, are calculated differently, and are used for different decisions. This article walks through what events and sessions actually count in GA4, how every behavior gets recorded as an event under GA4's event-based design, and which metric to look at in which scenario. TL;DR Event count = +1 per user action / Session count = number of session_start event fires — page views, scrolls, clicks are each one event; each visit is one session In GA4, sessions and PVs are both recorded as "events" — every behavior lives in the same box called "event," which is why event count is typically larger than session count Use sessions for traffic analysis, events for behavior analysis — "where they came from" → sessions; "what they did" → events; conversions are tracked as specific event types 1.…
