What this tool does

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.

How to use it

  1. 1

    Paste a URL with UTM parameters into the input field.

  2. 2

    Review each parameter with plain-language explanations.

  3. 3

    Fix warnings and copy the corrected tracking URL.

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.

Tips

  • Pair with the UTM builder when creating links from scratch.
  • Audit bio links and ad URLs quarterly for stale campaign names.
