Tracking & URLs

UTM Validator + Governance Linter

Paste your tagged URLs and catch case inconsistency, duplicate tracking signatures, and gclid/manual-tag conflicts before they cost you a reporting month.

How to use

Paste your URLs

One tagged URL per line — from any campaigns, any platform.

We check governance

Case inconsistency, duplicate campaign signatures, and gclid/manual-tag conflicts.

Fix before you launch

Catch tracking bugs before they cost you a reporting month.

URLs one per line

Paste URLs above to lint them.

What we check

Case inconsistency — the same source/medium/campaign value spelled with different capitalisation across your URLs (most analytics platforms treat these as separate values, splitting one channel into several report rows)
Duplicate UTM signatures — two different URLs sharing the exact same source+medium+campaign+term+content combination, which makes their traffic indistinguishable in reports
gclid / manual-tag conflicts — a URL carrying both Google Ads auto-tagging (gclid) and manual utm_source/utm_medium tags, which can conflict depending on your analytics setup
Missing attribution — a URL with neither utm_source nor gclid, which will land in “(direct)” or “(not set)” in most analytics tools
