What defines an Interaction Hit versus an Event Hit?
This might seem like a simple question – but it is vitally important when it comes to separating Google Analytics 4’s event-based data model from Universal Analytics’.
Behind GA4’s Event-Based Data Model
Universal Analytics (UA) recognizes seven separate hit types, i.e., types of trackable user interaction:
- Page view
- User timing
- App/Screen view
In UA, an Event represents a type of hit; in GA4, however, all hits are Events. This means that GA4’s event-based data model is fundamentally different: this goes far beyond adjustments in nomenclature.
