Why Link Validation Matters
Marketing data is only as good as the links that track it. A single typo in a UTM parameter can cause thousands of clicks to be miscategorized as "Direct" or "Referral" traffic in Google Analytics, effectively making your campaign look like a failure.
This UTM Checker acts as a quality assurance step before you launch. If you find errors, create fresh, clean tags using our UTM Builder.
Prevent Data Loss
Catch syntax errors like missing question marks (?) or ampersands (&) that break tracking completely.
Standardize Format
Ensure all your team's links use lowercase letters to avoid fragmented reporting (e.g., Email vs email).
Debug Redirects
Verify that anchor links (#) are placed after your UTMs, not before, or tracking will fail.
Common UTM Errors to Avoid
- Case Sensitivity:
Google Analytics is case-sensitive. Always use lowercase. Our tool flags uppercase letters as a warning. - Fragment Ordering:
If your URL uses an anchor (e.g., `#pricing`), it must come at the very end of the URL.
Correct:website.com/?utm_source=x#pricing
Wrong:website.com/#pricing?utm_source=x - Missing Source/Medium:
A campaign name alone isn't enough. Always pairutm_campaignwith at leastutm_source.
