Install the tracker
The Netaj tracker is a single, ~6KB gzipped JavaScript file that captures page views, clicks, and the events your experiments need. You install it once.
1. Get your tracking ID
From your dashboard, open Websites and copy the snippet shown after creating a website. It looks like this:
<script async src="https://api.netaj.io/t/nj_xxxxxxxx.js"></script>2. Paste it before the closing </head>
Add the script tag as close to the top of your <head> as possible. The tracker is fully async and won't block rendering, but loading it earlier means you start seeing data sooner.
3. Verify
Open your site in a fresh tab. Within 30 seconds, the website should flip from "Unverified" to "Verified" in the dashboard. If it doesn't, check that your domain matches what you configured.
If you're using Salla, Shopify, or WordPress, our platform integrations install the tracker automatically — you don't need this step.
