In Universal Analytics, interactions were tracked simply as “hits.” Now, in GA4, any engagement with your site or app is referred to as an “event.” Let’s break down event types.
- Automatically collected events are gathered automatically without additional configuration upon setup. You don’t need to turn them on, set them up, or customize them. These include session_start event, first_visit event, and user_engagement event.
- Enhanced measurement events are captured when you enable enhanced measurement upon setup. These include page views, scrolls to the bottom of a page, outbound link clicks, site searches, engagement with embedded videos, file downloads, and form interactions.
- Recommended events are implemented with predefined names and parameters. Google recommends a set of events based on your business vertical.
- Custom events can be implemented when no other pre-existing event suits your measurement needs. You will need to create custom reports or explorations to analyze these events.
