# Short links

Every cloud project has short links at `https://sh2.uk/<code>`, for example `https://sh2.uk/launch`. The code sits directly after the domain, without an `/l/` prefix. Use the short URL shown in the dashboard when sharing a link or creating a QR code.

A link has one or more **destinations**, each with a weight and optional country and device rules. They are useful for campaigns, for QR codes, and for testing landing pages on sites where you cannot install anything.

## Destinations

```json
{ "destinations": [
  { "url": "https://example.com/",       "weight": 50, "label": "current" },
  { "url": "https://example.com/start",  "weight": 50, "label": "new landing" },
  { "url": "https://example.com/de",     "weight": 100, "countries": ["DE", "AT", "CH"] },
  { "url": "https://m.example.com/",     "weight": 100, "devices": ["mobile"] }
] }
```

Matching targeted destinations take priority and are chosen by weight. When none match, the link uses the untargeted destinations. A cookie makes the choice **sticky**, so a visitor who returns lands on the same page. UTM parameters and any other query string on the short link are forwarded unless the destination already defines the same parameter.

## Stats

Total clicks, unique visitors, daily clicks, and breakdowns by destination, country, device and referrer.

## QR codes

Each link has a QR code in the dashboard with a PNG download. For colors, a logo and other payload types use the [QR code generator](/tools/qr-generator) with the short URL.

## Links as a lightweight test

Two weighted destinations are a redirect test without the SDK or the script. The dashboard shows the split and the clicks; to judge conversions you need a goal on the destination pages, which is what a [redirect experiment](/docs/redirect-experiments) with the drop-in script gives you. The "Create experiment and its link" option creates the experiment and opens a prefilled link form for you to save. Short-link clicks alone are not experiment exposures; install experiment tracking on the destination site to measure conversions.

## Redirect behavior

The public redirect is `GET https://sh2.uk/<code>` and answers `302`. The API-host route `GET https://go.splithub.io/l/<code>` also remains supported, but the dashboard uses the shorter `sh2.uk` URL. Unknown links return `404`; paused links and links that have reached their click limit return `410`.
