Google Analytics has changed significantly over the years. Universal Analytics was once the standard analytics platform for many websites but Google Analytics 4 has become the modern platform for understanding customer behavior.

GA4 was designed to provide a more flexible way to measure interactions across websites and apps. It focuses more on events and user behavior which can give businesses a broader view of the customer journey.

What Was Universal Analytics?
Universal Analytics was based largely around sessions and pageviews.
A session represented a group of interactions that happened during a period of activity. Businesses used Universal Analytics to monitor traffic sources pageviews sessions bounce rate and other website metrics.
It became a popular tool for understanding website traffic and digital marketing performance.
However customer journeys became more complex as people started interacting with businesses across websites apps and multiple devices.
What Is Google Analytics 4?
Google Analytics 4 uses an event-based data model.
Instead of relying mainly on sessions GA4 records interactions as events. These events can include page views clicks purchases form submissions and other actions.
This approach allows businesses to create a more detailed picture of how users interact with their digital platforms.
GA4 can also be used to measure activity across websites and apps which makes it useful for businesses with multiple digital properties.
Key Difference Between GA4 and Universal Analytics

This means that businesses need to understand their analytics data differently when moving from Universal Analytics to GA4.

Why Event Tracking Matters
Events are an important part of GA4.
Almost any meaningful interaction can be represented through an event.
For example a user could view a product click a button submit a form or complete a purchase.
Tracking these interactions allows businesses to understand more than basic page visits.
This can be especially useful for websites where important actions happen beyond simply visiting a page.
GA4 and User Journeys
Modern customers often interact with businesses through multiple channels.
Someone might discover a business through Google Search visit the website from their phone return later using a computer and eventually make a purchase.
GA4 is designed to provide a broader view of these interactions.
Understanding the customer journey can help businesses identify where users engage and where they may need additional information before converting.
GA4 for Digital Marketing
