Optimizing Your Analytics GA4’s Advanced Event Tracking and Essential Event List


GA4 introduces a new measurement model that focuses on events and user parameters, shifting away from the session-based model of Universal Analytics. This change is more than a technical adjustment; it’s a strategic move towards understanding user behavior in a more granular and flexible way. GA4’s event-based model allows for a more comprehensive and user-centric view of the data, enabling businesses to capture and analyze user interactions more effectively.

3. Enhanced Measurement: This feature in GA4 automatically collects data on scrolls, outbound clicks, site search, video engagement, and file downloads.

4. Custom Events: GA4 allows the creation of custom events to track specific interactions that are unique to your business needs.

6. User Properties: GA4 lets you define user properties, which are attributes that can be used to segment and understand your audience better.
