A free browser-based UTM builder for external campaigns. Replace campaign tags, retain other URL parameters and fragments, and copy the result. No account, analytics or form-data upload. An original practical tool from SEM Lion.


We built this small tool around a recurring campaign handoff problem: preserving the destination URL while applying a consistent set of campaign tags. It runs in your browser, replaces the five standard UTM values and preserves unrelated query parameters and page fragments. Empty optional fields remove old values. It is intended for external campaign links; avoid adding UTM tags to internal navigation, and never put personal or confidential information in a URL. This is an original SEM Lion resource. The source code is available in the linked repository. Feedback on the naming workflow is welcome.
