UTM Link Builder

The UTM Link Builder appends utm_source, utm_medium, utm_campaign, utm_term and utm_content parameters to a URL so Google Analytics and other tools can attribute traffic to the exact campaign, email or social post that sent it — with a running history of the last 10 links generated so a whole campaign's worth of links can be built without losing track of what's already been made. Whether you want a quick utm builder for a single tweet or a full campaign url builder that works as a utm link generator, this is it — every field maps directly to the utm parameters generator naming used in Analytics reports.

It's used when launching a multi-channel campaign and needing a UTM-tagged link for each platform (Instagram bio, newsletter, a paid ad, a partner's post), when standardizing on consistent source/medium naming across a team so reports in Analytics don't fragment into inconsistent variants like 'FB' and 'facebook' and 'Facebook Ads', and when quickly building one tracked link to paste into a single tweet. Source and medium fields suggest common values (facebook, instagram, email, cpc, social, referral) via autocomplete, but accept any custom text, since every team's naming convention differs.

The builder validates the base URL and requires source, medium and campaign — the three parameters Analytics needs at minimum to attribute a session — while term and content stay optional for the finer-grained cases (term for paid search keywords, content for A/B testing two links to the same destination). Every generated link is properly URL-encoded, so a campaign name with spaces or special characters doesn't break the resulting URL. History is saved to your browser's local storage only, never sent anywhere, and can be cleared per-entry.
