UTM Builder — free online link tagging tool
You shared a link in a newsletter, a post, and an ad, and now you have no idea which one actually brought people in. The fix is small tags on the end of your link that tell your analytics where each visitor came from. Typing those by hand is fiddly and easy to get wrong. We added a free tool that does it for you — UTM Builder — right in your browser.
What it does
You paste your link and fill in the campaign tags — source, medium, campaign, and a few more — and it gives you back one clean, properly encoded link. No more wondering whether you spelled a tag right or broke it with a stray space.
Nothing leaves your device
The whole thing runs in your browser. Your links and tags are never uploaded anywhere and nothing is saved. When you close the tab, it's all gone.
How to use it
- Open UTM Builder and paste the link you want to track.
- Fill in the tags you care about — source, medium, campaign, and any extras.
- Copy the finished link and use it wherever you're sharing.
It's free with no limit. There are more small tools on the Apps page.
