Add UTM tags to the links you share, so your analytics shows which post, platform or channel each visitor came from. Pick a preset for a common launch channel or fill in your own, and copy a clean, correctly encoded link.

The tool itself is interactive: open [UTM link builder](https://indielaunch.dev/tools/utm-builder) in a browser to use it.

## How to use it

1. Paste your landing page's address.
2. Pick a preset (X, LinkedIn, Reddit, Product Hunt, IndieLaunch, email) or fill in source, medium and campaign yourself.
3. Copy the link and use it wherever you share. Keep the same naming every time so reports group cleanly.

## What you get

- utm_source, utm_medium, utm_campaign, and the optional utm_term and utm_content.
- Keeps any query string your link already has, and replaces old utm_ values instead of doubling them.
- Warns about spaces and capital letters, which split one channel into several rows in most analytics tools.

## FAQ

### What are UTM parameters?

UTM parameters are tags added to the end of a link, like ?utm_source=x&utm_medium=social. Analytics tools such as Google Analytics, Plausible and Fathom read them to record where a visitor came from. They don't change the page the link opens.

### Which UTM fields do I need?

utm_source (the site or platform, like x or indielaunch), utm_medium (the kind of channel, like social, email or referral) and utm_campaign (your name for the push, like launch-week). utm_term and utm_content are optional, for telling apart keywords or two links in the same post.

### Do UTM links hurt SEO?

Not when the page has a canonical tag pointing at its clean address, which most sites and frameworks add. Use UTM links for the places you share by hand, not for links between your own pages: those would reset the visitor's original source.

### Should UTM values be lowercase?

Yes. Most analytics tools treat "X" and "x" as different sources, so mixed case splits one channel into several rows. Use lowercase and dashes instead of spaces.
