# Tracking links

> Create campaign links with UTMs and a stable Datalyr identifier.

Tracking links bundle a destination with campaign parameters and a unique `lyr` value. Use them for ads, partners, creators, QR codes, or any placement where you control the destination URL.

## Create a link

1. Open **Track** and select **Create link**.
2. Choose a verified first-party domain, or select **No domain (param link)**.
3. Enter the destination and a recognizable internal name.
4. Choose **Web page** or **App install**.
5. Add the source, medium, campaign, and any optional content or term values.
6. Create the link, copy it, and test it before publishing.

For app-install links, provide the appropriate App Store and Play Store destinations. Platform presets can help populate common ad macros, but you should confirm the generated URL against the ad platform before launch.

## Read link activity

The Track table shows each link and its activity. Search by name, `lyr`, destination, or campaign. Open a link to inspect its share URL and recent events. The selected date range controls activity stats, while search and filters control which saved links appear.

## UTMs and `lyr`

UTMs keep campaign labels readable across analytics and ad tools. The `lyr` value gives Datalyr a stable identifier for the link. Use both when possible; do not manually reuse one link's `lyr` on a different campaign.

<Note>
  A redirect click proves the link was opened. Attribution still depends on the rest of the journey reaching a tracked site or app and preserving supported identity or campaign context.

## Before launch

* Test the final ad URL, including platform macros.
* Confirm the redirect reaches the expected page or store.
* Open **Live** or **Events** and verify the visit contains the expected campaign values.
* Complete one test conversion and confirm it is connected to the link.
