Conversion Tracking with Firebase Analytics and UTM on Android

Question

I need to implement conversion tracking on my android app using firebase analytics.

In order to do that I will add some UTM parameters to my links, and that links will open a screen on my android app (using deep linking) and then I think I will need to send those parameters to Firebase.

What I want to know is what is the right/common approach to do this? Should I parse the URL on opening the app, save the UTM parameters and send them later when a conversion occurs?

How shold I send them to Firebase? Using an extra parameter or user properties?

If a conversion occur after an year, does it make sense to send the UTM parameters to firebase as well?

Answer 1

Firebase Analytics automatically extracts those URLs with utm_* params and logs campaign events. When a conversion event occurs, they will also automatically attribute to the correct campaign events, so you don't have to parse the URL.
