Google Analytics 4 (GA4) is the latest version of Google Analytics, and it offers a number of new features and capabilities over its predecessor, Universal Analytics (UA).
One of the biggest differences between GA4 and UA is the way that they collect and process data. GA4 uses a event-based data model, which means that every interaction with your website or app is tracked as an event. This includes things like page views, button clicks, form submissions, and downloads. UA, on the other hand, uses a session-based data model, which means that data is collected for each user session. A session is defined as a period of time during which a user interacts with your website or app without leaving.
Another key difference between GA4 and UA is the way that they handle cross-platform tracking. GA4 can track users across multiple devices and platforms, such as your website, mobile app, and social media. UA, on the other hand, can only track users across multiple devices if they are using the same browser.
GA4 also offers a number of new features and capabilities that are not available in UA, such as:
- Machine learning: GA4 uses machine learning to provide insights into user behavior and identify patterns that may not be visible with traditional analytics methods.
- Personalization: GA4 can be used to personalize the user experience on your website or app based on their past behavior.
- Attribution modeling: GA4 offers a more advanced attribution model that can help you to understand which marketing channels are driving the most conversions.
If you are looking for a more comprehensive and flexible analytics solution, then GA4 is the better choice. However, if you are already familiar with UA and are not comfortable with the changes in GA4, then you may want to stick with UA for the time being.
Here is a table that summarizes the key differences between GA4 and UA:
| Feature | GA4 | UA |
|---|---|---|
| Data model | Event-based | Session-based |
| Cross-platform tracking | Yes | No (with some workarounds) |
| Machine learning | Yes | No |
| Personalization | Yes | No |
| Attribution modeling | More advanced | Less advanced |

Ultimately, the decision of whether to switch to GA4 or not is up to you. However, if you are looking for a more modern and feature-rich analytics solution, then GA4 is the better choice.
