UTM parameters are not working in Google Analytics 4? Reasons and solutions

If you are tagging your marketing campaigns with UTM parameters (e.g., ) but you can't see their data in Google Analytics 4, there are several potential reasons.
In this video, I explain the most popular issues:
* Server redirects
* JavaScript redirects
* Invalid UTM parameters
* UTMs are removed/overwritten on tag/tracking code level
* Link with UTM parameters was clicked in the middle of a session
* Missing tracking code on a landing page
* Consent-related issues

Thanks Julius, consent one was super helpful and i think super relevant at the moment with the increasing uptake of cookie banners/consent mode/opt in analytics

[@Monirul_IslamBD]

This is useful. Thanks Julius. 👍

Hello, how are you? You mentioned in the video that I cannot create my own UTM parameters. But I would like to use more parameters in addition to the standard GA4 parameters. Since I want more information about the customers, I imagine I should register new dimensions in GA4, but I am a bit confused about how to do it. Can you explain it to me, or do you have a video that talks about this?

[@AnalyticsMania]

Yoi can't do that because GA4 does not support session scoped custom dimensions. Use UTMs that are supported by ga4

Hi man you are the best, maybe you will never read this but can you do a video on how to handle staging and production environments, I want to be able to have different Google tag measurements ids for testing and production, and to be honest Environments in GTM doesnt help or maybe I'm using it wrong

Speaking about reason #5, won't it work properly if i set attribution model at last click?

[@AnalyticsMania]

No, it won't

[@PavelTimoshek]

​@@AnalyticsMania hmm, this is a surprise. I thought it happens only in user-/session- attribution reports, but not event-. So can you refer to some article with potential solutions please?
