UTM Naming Convention Builder & Validator

Define your team's UTM taxonomy rules once, then paste any campaign URL to check it follows them. Keeps every channel consistent without a spreadsheet.

Runs entirely in your browser. Nothing is uploaded or stored.

How it works

STEP 1

Set your rules

Choose enforcement options: force lowercase, require snake_case, and optionally restrict allowed values for each UTM parameter.

STEP 2

Paste a URL

Drop any campaign URL into the validator. The tool parses every UTM parameter and checks it against your rules.

STEP 3

Fix & copy

See a colour-coded report with exact issues. Use Auto-fix to apply your rules, then copy or download the corrected URL.
