1. What Is Google Analytics 4 (GA4)?
Google Analytics 4 is Google’s latest analytics platform designed to track user-centric behavior instead of session-based activity. Unlike the older versions known as Universal Analytics that tracked sessions, GA4 focuses on how users interact with your website or app across multiple devices and touchpoints by tracking events and users.
Every interaction such as page views, clicks, scrolls, and video plays is treated as an event. This makes GA4 more flexible, more powerful, and better suited for modern digital experiences. For example, if a user visits your blog on their phone, returns later on a laptop, and then signs up for your newsletter, GA4 can connect these actions as one user journey.
3. GA4 vs Universal Analytics: What Changed?
Understanding the difference between GA4 and Universal Analytics helps you avoid frustration and ensure efficient utilization of Google Analytics 4. Compared to the older version, GA4 has had some major changes given below:
Event-based tracking: Everything is an event in GA4
No views: GA4 uses data streams instead
Improved privacy controls which is designed for a cookie-less future
Predictive metrics that uses machine learning for insights
Cross-platform tracking with websites and apps in one property
The real impact of these changes is that marketers now focus less on sessions and more on engagement, retention, and conversions.

GA4 defines engaged sessions as:

Or triggering a conversion
Understanding these terms will make everything else easier.
