In mid-October, Google introduced Google Analytics 4 (GA4) to the world. This is the largest update to Google Analytics since 2012 when Universal Analytics was unveiled.
There is a lot of excitement with the direction Google is taking the product, but there are also a lot of questions due to the fundamental change with how GA4 collects and will report on data.
The new GA4 (Google Analytics 4) properties (previously called ‘App + Web’ properties) consolidate data from websites and mobile apps in a single set of reports, allowing users to perform cross-platform analysis. They achieve this by letting you collect data from your mobile app (using Firebase) and your website (using the Global Site Tag or Google Tag Manager).
