Free UTM Campaign URL Builder

UTM parameters are tags you add to a link (utm_source, utm_medium, utm_campaign, and optionally utm_term and utm_content) so analytics tools like Google Analytics can attribute the visit to a specific campaign. For example, a link in your newsletter might use utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale.

Source, medium, and campaign are the three you should always set — they’re what most analytics reports group by. Term (for paid keywords) and content (to distinguish two links to the same place, e.g. for A/B tests) are optional but useful.

UTM values are case-sensitive in analytics: “Email” and “email” are counted as two separate sources, which fragments your reports. This tool forces lowercase by default so your campaigns stay consistent. Avoid spaces too — use underscores or plus signs.

No. The URL is built entirely in your browser as you type — nothing is uploaded or stored. Copy the finished link and use it anywhere you share the campaign.
