Your GA4 Is Only as Good as Your UTMs

Here's a question for you.

How many different values do you have for utm_source in your GA4 property?

If your answer is "I don't know," you're not alone.

Many organizations assume their UTM naming is under control until they discover things like:

• facebook, Facebook, Facebook.com, fb, and paid-social all referring to the same source, this leads to fragmented attribution reporting

• Campaign names that were used once and never again, leading to unnecessary clutter.

• UTM links that are broken or point to pages that no longer exist.

• Marketing campaigns that no one on the team remembers creating.

• Traffic that doesn't map cleanly into your default channel groups, again leading to fragmented attribution reporting.

None of these problems actually break GA4, but they simply make your reporting less trustworthy.

Over time, inconsistent UTMs make it harder to answer basic questions like:

• Which campaigns actually performed best?

• How much traffic came from email?

• Which paid channels generated conversions?

• Why are there five different versions of the same campaign?

The good news is that these issues are easy to identify and fix, but you have to check and fix these issues actively.

This weekend, spend 15 minutes auditing your UTMs.

Since we do this for your clients on a regular basis, I built an automated UTM Insights tool that tells us exactly what’s wrong with the UTMs and what needs to be fixed.

You can either manually audit UTMs or use this free tool inside UTM Manager. It is called UTM Insights in the left menu bar.

Happy analyzing,
