Add Google Tag Manager to WordPress: Easy Integration Guide
Explanation
To add Google Tag Manager (GTM) to your WordPress site, you'll need to insert some code snippets into your theme. This allows GTM to track and manage your site's tags effectively.
Step 1: Add GTM to the Head Section
- Use a function to insert the GTM script into the head section of your site. This ensures the script loads early, which is crucial for tracking.
- The function is hooked to wp_head, which is a WordPress action that outputs content in the head section of your site.
Step 2: Add GTM to the Body Section
- Another function is used to add a noscript tag right after the opening body tag. This is a backup for browsers that have JavaScript disabled.
- This function is hooked to wp_body_open, ensuring it appears immediately after the body tag opens.
Important: Remember to replace 'GTM-XXXX' with your actual GTM container ID. This ID is unique to your GTM account and is necessary for the scripts to work correctly.
By following these steps, you'll integrate Google Tag Manager into your WordPress site, allowing you to manage and deploy marketing tags without modifying the code directly.
Code
<?php
// Add Google Tag Manager to WordPress
// Hook into wp_head to add the Google Tag Manager script in the head section
function wp_dudecom_add_gtm_head() {

})(window,document,'script','dataLayer','GTM-XXXX');</script>
