# Free UTM link builder for social campaigns

Add utm_source, utm_medium and utm_campaign to any link, with presets for each network, so analytics can tell which post brought a visit.

Paste a page address, choose a network preset or type a source and medium, name the campaign, and copy the tagged link. The builder keeps the rest of your link intact, replaces any old utm values instead of repeating them, and can lowercase everything so reports stay tidy.

## How it works

UTM tags are query parameters that analytics tools read. The builder adds utm_source, utm_medium and utm_campaign, plus optional term and content, and keeps your other parameters and any #fragment in place.

Use the same lowercase names every time. "Social" and "social" are two values to most reports.

> It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, [start a trial](https://get1post.com/signup.md) and open it in the composer.

## Questions

**Which tags are required?**

Source, medium and campaign. The builder asks for all three because analytics reports group visits by them. Term and content are optional.

**What if my link already has utm tags?**

They are replaced, not duplicated, so the link never carries two values for one tag.

**Do tags change what visitors see?**

No. They are read by analytics and ignored by the page. Long links count 23 on X however long they are.
