GA4 is an event-based platform; when a user returns to a site, GA4 saves all events they complete rather than starting a new session. It helps Google to more precisely de-duplicate users and highlights what people do on your site as opposed to just caring that they arrive.
Universal Analytics is based on sessions, but GA4 uses a new measurement model called the Event + Parameter model. A page view isn’t available on apps so here GA4 picking up common data in the form of events
Previously, you had to use the GA property built for monitoring website data if you wanted to measure your website usage statistics.
In Universal Analytics, if you want to measure your mobile app usage data, you need to use Google Analytics for Firebase or Google Analytics APP view.
There was no simple method to merge data from your mobile app and website for unified reporting and analysis. However, this has all changed with the introduction of GA4 property (formerly known as APP+Web Property).
Unlike Universal Analytics (UA), GA4 allows you to track the performance of a website, an app, or both a website and an app simultaneously. As a result, data collection from both a website and an app in the same GA property can simplify the statistical analysis, saving time and, therefore, money.
Even if you don’t have a mobile app, Google recommends that you establish and utilize the GA4 property alongside your GA3 property, as Google is likely to withdraw support for GA3.
We can test GA4 while continuing to use Universal Analytics! As a result, we may swap between attributes as needed.
This is a big challenge for SEO because GA4 will not be a perfect replacement for your GA3 property any time soon. It is still not commercially ready, owing to a lack of strong eCommerce reporting and attribution modeling. As a result, maintain your GA3 property intact.
On the other hand, with the GA4 + BigQuery integration, you’ll be able to analyze terabytes of raw data, gain insights from the platform’s machine-learning capabilities, and even stream data straight to BigQuery.
