Where to Paste the Gtag Tracking Code – The Recommended Location
According to Google’s official documentation, you should place the gtag.js snippet immediately after the opening <head> tag on every page of your site.
“Place the gtag.js snippet as close to the opening <head> tag as possible to ensure that Analytics captures the full page load.”
This is because the <head> section loads before the body, allowing the script to initialize early, ensuring accurate tracking.
Sample Placement:
<head>
<script async src="https://www.googletagmanager.com/gtag/js?id=GA_MEASUREMENT_ID"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'GA_MEASUREMENT_ID');
</script>
</head>
Static website
On a static website, knowing where to paste the Gtag Tracking Code is straightforward. Insert it right before the closing <head> tag to capture every visitor interaction from the moment the page loads.
Dynamic website
Dynamic websites require extra care in deciding where to paste the Gtag Tracking Code. Typically, it goes inside the global header file, ensuring it applies consistently across generated pages.

Gtag.js or Google Tag Manager?
