About this tool
Broken UTM links silently misattribute traffic in Google Analytics — wrong source names split campaign data across reports.
Paste any URL to validate parameters, see plain-language explanations, and fix issues before publishing.

Common UTM mistakes
Inconsistent casing (Instagram vs instagram), spaces in values, and missing utm_medium are the most frequent errors.
Use a naming convention doc and this debugger on every campaign link before it goes live.
Pro tips
- Pair with the UTM builder when creating links from scratch.
- Audit bio links and ad URLs quarterly for stale campaign names.
