What is GA4 and What Does It Do?

GA4 is not just an analytics tool; it’s a powerful solution to understand user behavior, enhance marketing strategies, and make more informed business decisions. With the retirement of Universal Analytics, transitioning to GA4 is no longer optional—it’s essential., has become an indispensable tool for marketers and businesses. But what exactly is GA4, and how can it benefit your business? Let’s take a closer look.

What is GA4?

Google Analytics 4 (GA4) is Google’s next-generation analytics service that replaces Universal Analytics. With a user-centric structure, it tracks all interactions on websites and mobile apps based on events. It provides a more flexible and detailed analysis of user actions such as page views, clicks, and video plays. Thanks to AI and machine learning support, it offers insights and helps deeply understand user behavior.

What is an Event?

In GA4, an “event” refers to any kind of interaction users perform on a website or mobile app. For example, clicking a button, playing a video, viewing a page, or submitting a form are all considered events. This structure allows for more detailed and flexible analysis of user behaviors.

What Does GA4 Do?

GA4‘s main purpose is to help you understand the user journey in complex digital environments and provide powerful insights to achieve your business goals. Its key features include:

1. Unified Platform Measurement: GA4 combines websites and mobile apps under a single property. This enables you to seamlessly track cross-platform behaviors such as a user interacting first on your app, then your website, and then returning to the app. You get a complete picture of the user journey.
   
2. In-Depth User Behavior Analysis: The event-based model allows you to measure each user interaction in detail. You can easily define and analyze important business activities like button clicks, video progress percentages, form starts, and specific downloads—not just pageviews.
   
3. Advanced Insights and Predictions: GA4’s powerful AI engine automatically detects patterns and trends in your data. It helps you develop proactive marketing and retention strategies by predicting high-value customers (purchase probability) or users likely to churn (churn probability).
   
4. Enhanced Audience Creation: Understanding user behavior in depth is key to building highly targeted advertising audiences. GA4 enables you to define audiences based on complex criteria (e.g., users who viewed certain products or completed specific events) and push them directly to platforms like Google Ads, maximizing your ad spend efficiency.
   
5. Improved Data Visualization and Customization: GA4 offers flexibility to create your own custom reports. With the Explorations feature, you can go beyond standard reports, analyzing your data in different dimensions and segments to find answers to critical business questions.
   
6. Future-Ready and Privacy-Focused: With increasing privacy regulations (like GDPR, CCPA) and cookie restrictions (Safari ITP, Firefox ETP, and the deprecation of third-party cookies in Chrome), GA4 is more prepared for the future with its data modeling capabilities. It also works better with consent management for user data.
   

GA4 is not just an analytics tool; it’s a powerful solution to understand user behavior, enhance marketing strategies, and make more informed business decisions. With the retirement of Universal Analytics, transitioning to GA4 is no longer optional—it’s essential.
