Build UTM tracking links fast. Add utm_source, medium, campaign, term & content, copy, and save a history. Free & private. UTM Builder makes campaign tracking links the easy way. Fill in the fields, watch your tagged URL build live, and copy it — with presets for your channels and a saved history of everything you've made. Built for marketers, no sign-up. Consistent UTM tags are what make your Google Analytics campaign reports actually readable. This keeps them clean and repeatable. No ads, no tracking. ━━━━━━━━━━━━━━━━━━━━ WHAT YOU CAN DO ━━━━━━━━━━━━━━━━━━━━ 🔗 ALL FIVE UTM PARAMETERS utm_source, utm_medium, utm_campaign, utm_term, and utm_content — with the required three clearly marked and a live preview of the final URL. ⚡ CHANNEL PRESETS One click applies common source and medium values for popular advertising, social media, email, and video marketing channels. You can also customise every value. 🧼 CLEAN, CONSISTENT TAGS Optional lowercase and space handling (underscore, hyphen, or keep) keep your values tidy — so "Spring Sale" and "spring_sale" don't split your reports. 🧷 SAFE URL MERGING If your URL already has query parameters or a #fragment, they're preserved and the UTM tags are added correctly. 🕘 COPY + HISTORY One-click copy, and your last 20 links are saved — reload any of them into the form, copy, or delete. ━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━ 100% free. No account. No ads. No analytics. No tracking. No network requests. It never reads the pages you visit — it requests only the "storage" permission to save your links and inputs locally, and includes no remote code. Perfect for marketers, growth teams, agencies, and anyone running campaigns. Made by the team at seolust.com.
