UTM Builder for URLs

You have quite a few options on using a UTM builder.

My favourite (if you use Google Chrome as your preferred search engine): link

Google chrome UTM builder plugin

Google’s official UTM builder

And Raven Tools have a clean page for it too.

Big change with UTMs that started really impacting things in 2021 was Apple really started scrubbing data from URLs and hiding sources so while these tools still work, they are not going to track everything like they used to.
