  • Migrating from UA to GA4 for Mobile and Setting up Custom Events in GTM: Documentation and Information Required

    Posted by Elijah on 5 February 2023 at 3:30 pm

    Hey there, I have these two Google Tag Manager containers for my Android and iOS. But I can’t find the tag for GA4 configuration or event. Can anybody show me how to move from UA to GA4 for my mobile and how to setup custom events in GTM? And what’s the deal with there being no measurement ID for Android and iOS to connect GTM to Analytics?

    You’re actually already on the right track! In fact, Firebase Analytics events are the same as GA4 events. So, you don’t even need to connect your GTM container for GA4 migration from GA3.

    The main thing you need to do is integrate Firebase Analytics into your mobile app. That’s how you’ll be able to pass events data into GA4. The cool thing about using GTM with this is you can actually add, modify, or delete Firebase events.

    Here is a useful link for you about Firebase Analytics: [https://firebase.google.com/docs/analytics](https://firebase.google.com/docs/analytics)

    Sure, I’d be happy to help guide you through it. In order to switch from UA to GA4 for your mobile, it’s important to remember that UA and GA4 are quite different in nature, with GA4 being event-based. You’ll start by setting up a new GA4 property in your Google Analytics, which manages data collection differently and offers more advanced analysis capabilities.

    Once that’s done, you can go ahead to Google Tag Manager and create a new GA4 Configuration tag. For setting up custom events, you would use the GA4 Event tag. Please note, both these tags are available under the ‘Tag Type’ when creating a new tag in GTM.

    As for the measurement ID in GA4, it’s a bit different than UA property tracking ID. You can locate this under Admin > Data Streams on your GA4 property. Once your application (Android / iOS) is linked, a new data stream will be created and you will see a ‘Measurement ID’ which is needed while setting up your GA4 Configuration tag in GTM.

    Hope this helps! Remember, transitioning from UA to GA4 might need a learning curve due to the difference in their architecture and data management.
