# Install tracking
The tracking snippet reports pageviews, custom events, scroll depth, and time-on-page. Everything downstream — CONSIDERATION counts, splits by UTM/device/country, email identity — depends on it.
:::tip The two-step install
1. **Paste the snippet** (this page, sections 1–4) — gives you anonymous traffic, country/device/UTM splits, and engagement metrics.
2. **Add one `identify()` call** (section 5) — links anonymous visitors to their email when they sign up, so first-touch attribution survives all the way to the paid purchase. Without this, FunnelFizz can't tell that the customer who paid today first visited 30 days ago via Twitter.
Both steps are necessary to get the value FunnelFizz is built for. :::
## 1. Grab the snippet[](#1-grab-the-snippet "Direct link to 1. Grab the snippet")
The onboarding wizard (or **Settings → Tracking sites**) gives you a snippet:
```
```
`YOUR_TOKEN` is unique to your site.
## 2. Paste it into ``[](#2-paste-it-into-head "Direct link to 2-paste-it-into-head")
As high in `` as possible, before other scripts.
Next.js (App Router)
```
import Script from 'next/script';
export default function RootLayout({ children }) {
return (
{children}
);
}
```
Astro / Remix / SvelteKit
In your root layout, add the meta + script tags inside ``. All three frameworks support raw HTML in layouts.
WordPress
Use any "Insert Headers and Footers" plugin → paste into the **Scripts in Header** box. Or edit `header.php` inside ``.
Webflow / Framer / Squarespace / Shopify
Site-wide **Custom Code → Head**. Paste both tags. Publish.
Plain HTML
Paste into `` of every page (or a shared include).
## 3. Multiple sites?[](#3-multiple-sites "Direct link to 3. Multiple sites?")
**Paste the same snippet into each one** (your main site, app, docs, blog).
To track the same visitor as one person across `example.com` and `app.example.com`, the cookie has to be set at the apex.
**For flat 2-label apex domains** (`example.com`, `myapp.io`, `acme.dev`), the script auto-detects the apex and sets the cookie domain to `.example.com` automatically — no flag needed.
**For multi-label TLDs** (`example.co.uk`, `mysite.com.au`), the auto-detect plays it safe and stays host-only. Set `data-cookie-domain` explicitly:
```
```
If you want subdomains tracked **separately**, set `data-cookie-domain="host"` to opt out of auto-detect — each origin gets its own visitor ID.
## 4. Verify[](#4-verify "Direct link to 4. Verify")
Visit your live site. The wizard auto-advances within \~5s once it sees the first event. Verification is host-agnostic, any URL with the snippet flips it to verified.
If nothing happens:
* View source, confirm `funnelfizz-verify` and `track.js` are actually on the page.
* Confirm `YOUR_TOKEN` was replaced with the real token in both the `` and `
