UTM Link Builder
Build campaign URLs with UTM parameters that any analytics platform can read.
About the UTM Builder
The UTM Builder generates campaign-tracked URLs by adding Google Analytics-compatible UTM query parameters — utm_source, utm_medium, utm_campaign, utm_term and utm_content. UTM tags are how you measure the impact of specific campaigns, ads, emails and referral links in Google Analytics 4, Plausible, Fathom, PostHog and virtually every other analytics platform.
Marketing teams, growth engineers and SEO specialists build UTM URLs constantly — for email campaigns, social posts, paid ads, partner links and offline QR codes. A consistent UTM taxonomy (agreed-on values for source and medium) is the difference between analytics data you can trust and a jumbled mess of one-off tags nobody understands three months later.
This tool follows Google's recommended parameter names and semantics, includes an auto-lowercase toggle (utm_source is case-sensitive!), and warns about common mistakes like using the same value for source and medium. Save your UTM patterns to a shared style guide, and use consistent values across every campaign for meaningful cross-channel attribution.
