# Install overview
> Add the Traceten snippet to your site in under 5 minutes. Pick your platform.
## One snippet, any platform
The Traceten snippet is a single `
```
Your site key comes from the dashboard. Each site you create gets a unique key. Do not share keys across domains.
`data-cookie-domain` is your own domain. It keeps one visitor as one visitor when they move between your subdomains, so an AI referral that lands on `example.com` still gets credit for a purchase that completes on `shop.example.com`. It is off until you set **Cookie domain**, either in the **Add site** form (we strongly recommend it) or later under the site's **Settings → Cookies**. Copy the tag from the dashboard rather than typing this value: once set, we render your registered domain onto it there, and a value the page does not belong to is ignored. See [Subdomains and cross-domain](/install/subdomains).
**These steps are also in the app.** Every guide below is rendered inside the dashboard with your
real site key filled in. Open **Sites → Install** for your site, or the setup flow you land in after
signing up, and pick the same platform. The install page walks three steps: add the script, follow
your platform, and verify, which turns green on the first pageview. To have a coding assistant do
the install, click **Set up with AI** there. It copies a prompt with your site key that adds the
snippet to your project and suggests goals, asking you before it adds any. With a cookie domain
set, the prompt also names your visitor cookie and has the assistant check every tag for
`data-cookie-domain`, telling you where it is missing.
## Pick your platform
Any static site or HTML template. Paste before ``.
Two methods: theme editor or the Insert Headers and Footers plugin.
Add to Project Settings under Custom Code.
Edit `theme.liquid` under Layout in your live theme.
Add to the App Router layout, or `_document.tsx` on the Pages Router.
## Prefer to send events from your backend?
To send events from your server instead of (or alongside) the browser, use a server SDK. Server delivery reaches the traffic the snippet cannot: ad-blocked visitors, privacy browsers, server-rendered flows, and background jobs.
The server SDKs live in their own section. See the [SDKs overview](/sdks/overview) to pick a language ([Node.js](/sdks/node), [Python](/sdks/python), or [Go](/sdks/go)), and the [Browser SDK reference](/sdks/browser) for the `window.traceten` client-side API.
## After installing
1. [Verify the snippet is firing](/install/verify). Check the dashboard within 30 seconds of a pageview.
2. If something doesn't work, see [troubleshooting](/install/troubleshooting).
3. Once verified, explore your [dashboard](/dashboard/overview). AI source data starts appearing within hours of real traffic.
