What this tool does
UTM Builder creates clean, correctly-encoded campaign URLs with UTM parameters for analytics tracking.
How to use it
- Enter your base URL.
- Fill in source, medium, campaign and any optional terms.
- Copy the tagged URL.
How it works
Your parameters are URL-encoded and appended as standard utm_* query parameters, producing a link analytics tools recognise.
Important considerations
- UTM parameters are visible in the URL — don't put sensitive information in them.
