UTM Builder Guide
Build and parse UTM campaign URLs with source, medium, campaign, term, content and id.
UTM parameters are labels in a URL that an analytics setup may use to identify where a visit came from. UTM Builder adds or reads these labels as text; it does not send the link to an analytics service.
Build and inspect a harmless link
Set Base URL to https://example.com/docs and Source (utm_source) to newsletter. Leave the other UTM fields blank. Result should show https://example.com/docs?utm_source=newsletter. Press Copy URL for that result. Paste it into URL to inspect under Parse a URL; after a brief pause, you should see a utm_source row with value newsletter.
Existing non-UTM query parameters are kept, but blank UTM fields remove matching UTM parameters already present in the base URL. A missing scheme is treated as HTTPS. Review the result before sharing: URLs can appear in browser history, server logs, and referrer data. Never put personal data or secrets into UTM values.

Questions you might have
- Does it shorten the URL?
- No. It only adds and reads parameters. Use your analytics platform’s shortener if you need a short link.
