Build clean, properly URL-encoded UTM tracking links for Google Analytics, GA4, Adobe Analytics, Matomo, and any other campaign-tracking tool. Live preview, one-click copy, no signup.
Paste your destination URL into the Website URL field.
Type the source, medium, and campaign name; add term and content if needed.
Click Copy to grab the tagged URL or Open to test it in a new tab.
One typo in utm_source and your campaign data splits into two rows in Google Analytics. The builder URL-encodes every value cleanly, replaces existing UTM tags on the destination URL, and outputs a sharable link.
Useful for social posts, email campaigns, paid ads, and any link where you need accurate attribution to credit the right channel.
Most UTM builders make you click Generate every time you tweak a field. This one updates the output URL on every keystroke, and runs full validation in parallel, so the inline status banner instantly tells you which required field is still missing or whether the URL parses. The result is a tight feedback loop perfect for iterating on a campaign launch list.
Every value is set via the standards-compliant `URLSearchParams.set()` API, which percent-encodes spaces, ampersands, plus signs, accented characters, and emoji exactly per the WHATWG URL spec. So `Spring Sale 2026` becomes `Spring%20Sale%202026`, never an unsafe `Spring+Sale` ambiguity that some campaign tools produce. Existing UTM params on the destination URL are removed before new ones are added, no duplicates.
Use the Open button to launch your tagged URL in a new tab, perfect for verifying that the destination renders correctly, that GA / GA4 picks up the campaign in real time, and that downstream redirects (CMS, ad platforms, link shorteners) preserve the parameters. The URL length and parameter count update in the stat row so you can spot a URL that is approaching your link-shortener or SMS provider limits.
Every keystroke is processed entirely in your browser using the standard `URL` and `URLSearchParams` APIs, there is no API call, no analytics on your campaign names, no logging. Use it freely for unannounced product launches, NDA-bound client work, internal A/B test variants, and competitive PPC strategies without leaking any of it to a third party.
