GrowthOptix's script enables the tracking of page views, UTM parameters, referrers, landing pages, and all attribution data.


1. Copy your script from GrowthOptix

  1. Log in to GrowthOptix.

  2. Go to Marketing Attribution → Tracking

  3. Click Copy Script.

Important: Every script contains a unique identifierKey. Do not copy the example below; always use your own.

Example script (for demonstration only)

<!-- Start of GrowthOptix script (example only) -->
<script>
var script = document.createElement('script');
script.src = "https://cdn-staging.growthoptix.com/tracking/index.iife.js";
script.defer = true;
script.onload = function() {
window.GrowthOptix.init({
identifierKey: "EXAMPLE-IDENTIFIER-12345" // Example only
});
};
document.head.appendChild(script);
</script>
<!-- End of GrowthOptix script (example only) -->

2. Paste the script inside your website’s <head>
