GA3 to GA4 Migration - High-Level Overview

On March 1st, 2023, Google automatically migrated all older GA3 properties to the new GA4 properties. If you want to know about the GA3 to GA4 migration and what it entails, this video will cover it.

Google Analytics 3 (GA3) and Google Analytics 4 (GA4) are two different versions of Google Analytics, which differ in several ways. Here are the primary differences between GA3 and GA4:

User Interface: GA4 has a completely redesigned interface, which is more streamlined and user-friendly compared to GA3. GA4 has also introduced new features such as a more intuitive user interface, machine learning models, and cross-device tracking.

Data Collection: GA4 uses a different data model than GA3. GA4 uses an event-based data model, which means that all user interactions are recorded as events, and these events are grouped into sessions. This is different from GA3, which tracks page views and sessions.

Reporting: GA4 has a more advanced reporting interface than GA3. GA4 provides more insights into user behaviour and allows for more granular analysis of user interactions.

Cross-Device Tracking: GA4 has improved cross-device tracking capabilities compared to GA3. GA4 uses machine learning models to stitch together user interactions across multiple devices and platforms.

Machine Learning: GA4 incorporates machine learning models, which help to automatically identify important user segments and insights from the data.

Customisation: GA4 provides more customisation options than GA3. For example, GA4 allows users to define custom events and parameters, which can help to track more specific user interactions.

Overall, GA4 represents a significant upgrade over GA3, with a more advanced user interface, more advanced data collection and reporting, improved cross-device tracking capabilities, and better customisation options.
