UTM LINK BUILDER
Build campaign URLs with UTM source, medium, campaign, content and term parameters. Preserve existing URL parameters and copy a properly encoded tracking link.
THE CLEARER PICTURE

A LITTLE CONTEXT GOES A LONG WAY
Source identifies where the visit came from; medium describes the channel; campaign groups related activity. Decide how your team uses case, spaces and separators before you publish links. For example, newsletter / email / autumn_launch is easier to group than several inconsistent spellings.
The builder preserves unrelated query parameters and page anchors. It replaces existing versions of the six supported UTM fields with your current entries, and removes optional fields you leave blank. Spaces and special characters are encoded so the link remains a valid URL.
UTM parameters label a URL; they do not install analytics or guarantee attribution. Your destination’s analytics system must read the parameters, and redirects need to preserve them. Avoid using UTM tags on internal navigation where they can interfere with campaign interpretation. Never put personal information or secrets into campaign values.
