What is the gtag Tracking Code?

Global Site Tag (GTAG.JS) is the recommended JavaScript tag frame to Google to send data to Google Analytics, Google Ads and Google Marketing platforms. It acts as a basic code that captures and forwards the data on your Google Account.

Importance of Correctly Placing the gtag Tracking Code

Before diving into where to paste the gtag tracking code, it’s crucial to understand why proper placement matters:

  • Data Accuracy: If the code loads too late, it may miss tracking page views or events.
  • Page Speed: Improper placement can hinder your site’s performance.
  • Tag Management: Ensures compatibility with other tags and triggers in your analytics setup.

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>

Can You Place gtag.js in the Body Tag?

Technically, yes—you can place the code in the <body> section, but it’s not recommended. Doing so may delay script execution, causing you to miss key events such as the initial page view. If you absolutely must place it in the body, try to position it at the top.

Still, to ensure accuracy and optimal performance, remember this rule: Always paste the gtag.js code right after the opening <head> tag.

What Happens if You Place the gtag Code Incorrectly?

Understanding the implications of poor code placement reinforces the importance of knowing where to paste the gtag tracking code:

  • Delayed Page View Tracking: If placed too late, you miss valuable data.
  • Tag Conflicts: Other scripts (like GTM or Facebook Pixel) may interfere.
  • Incorrect Event Attribution: Analytics reports could show distorted metrics.

A recent Google Analytics report shows that 26% of small business websites have incorrectly implemented tags, leading to data loss.

Using Google Tag Manager with gtag.js

If you use Google Tag Manager (GTM), you don’t need to install the gtag.js snippet separately. GTM acts as a container, and you can configure gtag settings within it.

However, if you’re not using GTM, knowing where to paste the gtag tracking code becomes even more critical.

How to Verify if Your Gtag is Installed Correctly

After placing the code, always test it. Here’s how:

  • Google Tag Assistant: A Chrome extension to validate tag placements.
  • Real-Time Reports in GA4: Open your website and check if real-time data appears.
  • Google Analytics Debugger: Another Chrome extension useful for troubleshooting.

This step is essential regardless of how many times you’ve added the tag—verify every time.

Advanced Tips for Gtag Configuration

  • Multiple Properties: Use multiple gtag(‘config’, ‘GA_MEASUREMENT_ID’) lines for multiple accounts.
  • Event Tracking: Configure custom events like button clicks or form submissions.
  • Cross-Domain Tracking: Use additional configuration for cross-site analytics.

For advanced setups, a Google analytics audit checklist is invaluable.

Mobile Optimization and Gtag

As more than 60% of traffic comes from mobile (Source: Statista), your gtag tracking must be optimized for responsive environments.

If you have a custom-coded mobile site or PWA, remember:

  • Place the code in the head of each HTML template.
  • Use async to improve load speed.

This approach complements your responsive website development services strategy.

Common Mistakes to Avoid

  1. Placing the gtag code at the bottom of the <body>.
  2. Not replacing the GA_MEASUREMENT_ID with your actual ID.
  3. Copying only part of the code.
  4. Using both gtag.js and GTM without coordination.

Why Businesses Should Care About Proper Gtag Placement

Also, if you’re working with a b2b web design agency or developing a complex platform like a travel website development company might offer, ensuring accurate tracking setup from day one is essential.
