# UTM builder

> Assemble correctly-formatted UTM links, with a source/medium cheat-sheet — free, nothing stored.

The free UTM builder at
[trackrev.io/tools/utm-builder](https://www.trackrev.io/tools/utm-builder) helps you build tagged
links by hand. Everything is assembled in your browser — nothing is stored.

## The five UTM parameters

| Parameter      | Required | Example         |
| -------------- | -------- | --------------- |
| `utm_source`   | ✅        | `newsletter`    |
| `utm_medium`   | ✅        | `email`         |
| `utm_campaign` | ✅        | `spring_launch` |
| `utm_term`     | —        | `running_shoes` |
| `utm_content`  | —        | `header_cta`    |

Enter your destination URL and the parameters, and the builder produces the full tagged link to
copy.

## Best practice

* **Be consistent** — pick one casing (lowercase) and stick to it; `Email` and `email` are
  different values to analytics.
* **Use a naming convention** — e.g. `utm_source` = the platform, `utm_medium` = the format
  (social, email, cpc), `utm_campaign` = the initiative.
* **Don't tag internal links** — UTMs are for inbound links from other sites, not links within your
  own site.

<Tip>
  The UTM builder is handy for one-off links. For anything you'll **track and attribute**, create a
  [TrackRev tracking link](/link-tracking/create-links) instead — it applies the right UTMs per
  channel automatically and joins the click to revenue. The builder is a manual helper; tracking
  links are the real thing.
