Google Tag Manager (GTM) is a powerful tool that allows you to manage tracking codes without modifying your website’s code repeatedly. Many WordPress users rely on plugins to integrate GTM, but adding it manually provides better control and faster site performance. In this guide, you’ll learn how to add Google Tag Manager to WordPress without plugin in a few simple steps. Let’s dive in!
Why Use Google Tag Manager in WordPress?
Google Tag Manager simplifies tracking and analytics by managing scripts like:
- Google Analytics 4 (GA4) – Tracks website traffic and user interactions.
- Facebook Pixel – Helps with Facebook ad tracking.
- Google Ads Conversion Tracking – Monitors paid ad performance.
- Heatmaps & Other Analytics Tools – Provides deeper user insights.
Instead of adding these scripts individually, GTM allows you to manage them all in one place. This makes your site faster and reduces the risk of errors.
How to Add Google Tag Manager to WordPress Without a Plugin
Follow these steps to manually insert the GTM code into your WordPress theme.
Step 1: Create a Google Tag Manager Account
- Go to Google Tag Manager.
- Click Create Account and enter your account details.
- Add your Website URL and select Web as the target platform.
- Click Create and accept the terms.
Once done, you’ll receive two code snippets that need to be added to your WordPress site.
Step 2: Insert GTM Code in WordPress Header
The first snippet must be placed inside the <head> section.
- Log in to your WordPress Dashboard.
- Navigate to Appearance → Theme Editor.
- Open the header.php file of your active theme.
- Locate the
<head>tag. - Paste the first GTM code right after the opening
<head>tag.
Tip: If you use a child theme, edit the header.php file in the child theme to prevent losing changes after updates.
Step 3: Insert GTM Code in WordPress Body
The second snippet must be placed right after the <body> tag.
- In the Theme Editor, open the
header.phpfile again. - Find the
<body>tag. - Paste the second GTM code immediately after the
<body>tag. - Save the file and upload changes.
Now, Google Tag Manager is installed on your WordPress site without a plugin!
How to Check if Google Tag Manager is Working
After adding the GTM code, verify the installation with these steps:
- Use Google Tag Assistant – Install the Google Tag Assistant Chrome extension. Open your website and check if GTM is detected.
- Preview Mode in GTM – In your GTM account, click Preview, enter your website URL, and ensure GTM is firing correctly.
- View Page Source – Right-click on your website and select View Page Source. Use Ctrl+F and search for “GTM-” to check if the code exists.
