GA4's Event-Based Design: Why Event Counts Always Exceed Session Counts

GA4 represents a paradigm shift from session-based to event-based analytics architecture, but this fundamental difference is frequently misunderstood by analysts interpreting website performance. Understanding which metric to use—events for behavior analysis versus sessions for traffic analysis—is critical for accurate business decision-making, as confusing them leads to completely misaligned insights. The event-based model counts every user action individually, creating vastly higher event totals than session counts, and this design principle underlies all of GA4's measurement logic.
