UTM Link Builder

UTM parameters are how marketers answer the only question that matters about a campaign: did it work? Add utm_source, utm_medium and utm_campaign to a link, and your analytics can attribute every visit — this many from the newsletter, that many from the Instagram bio, those from the Google Ads campaign. Without them, everything arrives as anonymous "direct" traffic and the question is unanswerable.

This builder assembles the URL correctly: values are properly URL-encoded (spaces and special characters break naive hand-built links), parameters append correctly whether or not the destination URL already has a query string, and the three conventionally required parameters — source (where the click comes from), medium (the channel type), campaign (which push) — are marked and gently enforced. One-tap presets fill the standard source/medium pairs: google/cpc, facebook/social, newsletter/email and the other combinations analytics tools expect.

The discipline that makes UTM data useful is consistency, and the FAQ covers the conventions: always lowercase (analytics treats "Email" and "email" as different channels), hyphens instead of spaces, and the same naming scheme across every campaign. Build the link, copy it, and use it everywhere that campaign runs — your analytics reports become dramatically more truthful within a week.
