UTM Builder
Add UTM parameters to any link so your analytics can tell where traffic came from. Handles URLs that already have query strings, which is where hand-built UTMs usually break.
Free, no signup, and everything is calculated in your browser.
What each parameter is for
utm_source is where the traffic came from (newsletter, twitter, partner-site). utm_medium is the channel type (email, social, cpc). utm_campaign names the initiative.
utm_term and utm_content are optional — term for paid keywords, content for distinguishing two links in the same email.
Keep them lowercase and consistent. Analytics tools treat Newsletter and newsletter as different sources, which quietly splits your reporting in half.
Questions people ask
Do UTM parameters affect SEO?
Not directly, but tagged URLs can create duplicate crawlable versions of a page. Use them on links you share, not on internal navigation, and set a canonical URL on the page.
Is my data sent anywhere?
No. The URL is assembled in your browser and never leaves it. Nothing here requires an account.
Is a UTM builder the same as a UTM generator or UTM creator?
Yes — different names for the same thing: a form that assembles a URL with utm_ parameters attached. This one also handles links that already carry a query string, which is where a hand-typed UTM usually breaks.
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign. Google Analytics attributes the visit as long as source and medium are present, but campaign is what makes the report readable. utm_term and utm_content are optional and mostly useful for paid search and for telling two links in one email apart.
Can I shorten the tagged link?
Yes, and for print or social you probably should — a UTM'd URL is long and ugly. Build the full tagged URL here first, then shorten it; the parameters survive the redirect and analytics still sees them. For posters, turn it into a QR code instead.
