What the UTM checker looks for
- Missing source, medium or campaign
- Mixed upper and lower case
- Spaces and special characters
- Medium values GA4 does not map to a channel, which show up as “Unassigned”
Why broken UTM links matter
When a UTM link is wrong, GA4 can’t tell where the visit came from. The campaign then looks weaker in your reports than it really is, and budget decisions get made on incomplete data.
Checking links before a campaign goes live is much easier than cleaning up reports afterwards.
Frequently asked questions
Is the UTM checker free?
Yes. You don’t need to sign up.
Can I check links for Google Ads, LinkedIn and Meta?
Yes. Paste any campaign URL.
What does “Unassigned” mean in GA4?
GA4 couldn’t match the visit’s source and medium to one of its channels, usually because the medium value isn’t one it recognises.
