UTM Link Builder

Build campaign-tagged URLs for Google Analytics, GA4, or any analytics tool that supports UTM parameters.

What is UTM Link Builder?

UTM parameters are query string tags (utm_source, utm_medium, utm_campaign, utm_term, utm_content) appended to URLs so analytics tools can attribute traffic to specific campaigns. They were introduced by Urchin (Google Analytics's predecessor) and are now the de-facto standard across analytics platforms. Use consistent naming — 'facebook' and 'Facebook' become two different sources in your reports.

Frequently asked questions

Which UTM parameters are required?
utm_source is required by GA4. utm_medium and utm_campaign are strongly recommended. utm_term and utm_content are optional.
Should I tag internal links?
No — tagging internal navigation resets attribution and breaks your data. Only tag inbound links from external sources.
