Free UTM builder
Add UTM tags to any link so your analytics can tell where a click came from. Fill in the fields and copy the tagged URL — it's free, needs no account, and is built right in your browser. Shorten the result on Shortlen when you're done.
What are UTM tags?
UTM tags are five small pieces of text you add to the end of a link — utm_source, utm_medium, utm_campaign, and the optional utm_term and utm_content. They don't change where the link goes; they just let analytics tools group clicks by where they came from. Keep them lowercase and consistent so your reports stay tidy.

Questions
Is this UTM builder free?
Yes. It's free, needs no account, and runs entirely in your browser — nothing you type is sent anywhere.
Which fields do I need?
Source, medium and campaign are the three most tools expect. Term and content are optional and used mostly for paid search and A/B tests.
Can I shorten the tagged link?
Yes — paste the tagged URL into Shortlen to get a short, branded version that keeps the UTM tags. See branded links for why that helps.
