UTM builder

Tag a campaign URL so clicks show up correctly in your analytics. Free, no signup, and nothing leaves your browser.

These are added to the destination URL, so your own analytics can attribute the visit. Anything already in the URL is kept.

What the five tags mean

  • utm_source — where the traffic comes from: newsletter, google, partner-site.
  • utm_medium — the kind of channel: email, cpc, social.
  • utm_campaign — the campaign this link belongs to: spring-sale.
  • utm_term — paid keyword, if you are running search ads.
  • utm_content — which version of the link it is: header-button vs footer-link.

Two rules that save you later

Pick a casing and never change it. Analytics tools treat Email and email as two different mediums, and you cannot merge them afterwards. Lowercase everything.

Tag the destination, not the short link. The tags have to arrive at the page being measured, so they belong on the URL the visitor lands on — which is what this builder produces.

A longer guide to UTM parameters covers naming conventions and the mistakes that cost you a quarter of attribution.
