Looking with considerable fear at the imminent end of the Universal Analytics era, probably many marketers will spend the next few months absorbing knowledge in the scope of Google Analytics 4. Just like everyone else I am also in the process – so I invite you to join me on the journey of switching from GA to the latest GA4 version. Today I will cover the most urgent topic, i.e. parallel account configuration. Here we go!

Śledzenie równoległe w dwóch wersjach

Until the final withdrawal from Universal Analytics, we have the option to configure both versions in parallel. Just go to Administration -> Service -> GA4 Configuration Assistant.

What to keep in mind – the data in GA4 will not be historically copied from the UA version. Using the GA4 assistant, simply check the “Enable data collection using existing tags” option and then a new site will be created with the basic data filled in (name, url, currency, time zone). The data should appear up to 30 minutes after setup.

Importantly, the different platform types differ minimally in configuration. This is usually due to the specifics of the new version, which combines data streams from different sources together.

  1. CMS system – some systems do not support the new version of the tag, hence additional measures are required. Currently GA4 tag is not supported by such websites as Magento, Presta, Shopify among others. It remains to implement the appropriate html fragment in the code. Detailed GA4 configurations for CMS.
  2. Site – For sites, the process of implementing the tag is exactly the same as the previous version. The only difference is the marking of G- before the ID number.
  3. App – from within Firebase you can link your account to GA4. We add a data stream with Android and IOS split separately, thus in one view will be data from all sources.

Differences between Universal Analytics and Google Analytics 4

  • tracking identifier – the current tracking code starts with “UA-“, in the newer version it is abbreviated “G-“
  • view – there are no more views, there is only account and service
  • no targets – they are replaced by event type
  • user – definition changes to “active user”


GA4 is the near future, and it’s already starting to make its way into the analytics world. The sooner we get to grips with using and analyzing data with this new version, the more understandable and useful it will become. In this article, I covered the basics of configuring GA4.

If you want to learn about the basic differences in a slightly broader context, I invite you to the post Google Analytics 4 comprehensive guide. More articles on this topic will appear on a regular basis. I also encourage you to share this post on your Linkedin channel, for which I will be extremely grateful.

Looking forward to reading it next time!
