Google Analytics 4, also known as GA4, is available from mid/late 2020.
We are facing a new measurement platform that is going to change the paradigm that we had established until now. From the way we collect data to how we are going to measure from now on to be able to make decisions that affect our Web / App or business.
GA4 is a new platform and as such it will require us to get used to the new concepts and ways of doing things. Little by little new documentation is appearing, much of it in English, and we are also hearing a lot of "Fake news" around it, such as that it is not a good idea to implement it yet or that we are going to lose the data we have collected so far with the previous version: Universal Analytics (AKA GA3).
I have started a series of articles, which will grow over time, in which I will give my opinion on different topics related to GA4 and I will leave tutorials on the implementation of different measurement solutions. Below is the list, which will be updated as I publish them.
