UTM Link Builder

UTM parameters are tags added to the end of a link as query parameters, like utm_source and utm_campaign. When someone clicks the link, analytics tools read those tags and group the visit under the campaign you set, so you can see which links drive traffic and conversions.

utm_source is where the traffic comes from (for example newsletter, google or facebook). utm_medium is the channel type (for example email, cpc or social). utm_campaign is the specific promotion name (for example spring_sale). Together they answer where a visit came from, how, and for which campaign.

In GA4 the values land in dimensions named Session source, Session medium and Session campaign. Open Reports, then Acquisition or Traffic acquisition, and group by those dimensions to compare your tagged links side by side.

Yes, keep them consistent. Analytics treats Email and email as two different mediums, which splits your reports. Pick one style, usually all lowercase with underscores instead of spaces, and reuse it for every link.

No. They are extra query parameters that the destination page ignores, so the visitor sees the same content. They only exist so analytics tools can attribute the visit to a campaign.

Yes. The link is built entirely in your browser, so the URLs and campaign names you enter are never uploaded or stored.
