Free UTM builder

Source identifies the referrer. Medium names the channel. Campaign names the initiative. Content can identify the creative, while term can identify a paid keyword. Pick one convention and use it across the account.

Google Analytics treats values as case sensitive. This builder preserves the case you enter. Prefer consistent lowercase names so a campaign does not split into separate report rows.

The default is an illustrative Facebook paid social campaign called autumn_sale, with video_a as the creative. The generated URL adds utm_source=facebook, utm_medium=paid_social, utm_campaign=autumn_sale and utm_content=video_a to the destination.

Existing query parameters and the page fragment stay in the URL. The five UTM fields in this form replace existing values of those fields; leaving content or term empty removes that tag. Spaces and reserved characters are encoded so an ampersand in a campaign name cannot become another parameter.

Open the generated URL yourself and check that redirects preserve its tags. Confirm that the destination's analytics implementation records the visit with the expected source, medium and campaign. Generating a URL alone does not install analytics or verify attribution.

For Google Ads, manual UTMs do not replace auto-tagging. Review the account's analytics setup before changing either. This builder creates literal URLs; it does not validate or execute platform-specific dynamic macros.
