How to Add Google Tag Manager (GTM) in Gutenify Using Global Code Settings?

Why Use Gutenify’s Global Code Feature?

No Theme File Editing: Avoids the need to modify theme files like header.php or functions.php.
Persistent Across Updates: Ensures your GTM code remains intact even after theme updates.
Centralized Management: Provides a single location to manage scripts that apply site-wide.

To add your Google Tag Manager (GTM) script using the Global Code feature in the Gutenify WordPress plugin, follow these steps:

Go to Gutenify Global Code Settings:

From your WordPress dashboard, navigate to Gutenify → Setting → Global Code.

Insert GTM Script into the Header:

In the Global Header Code section, paste the first GTM snippet provided by Google Tag Manager. This script should be placed within the <head> tag of your website.

<!-- Google Tag Manager -->
<script>
  (function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
  new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
  j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
  'https://www.googletagmanager.com/gtm.js?id=GTM-XXXXXXX'+dl;f.parentNode.insertBefore(j,f);
  })(window,document,'script','dataLayer','GTM-XXXXXXX');
</script>
<!-- End Google Tag Manager -->

Insert GTM NoScript into the Body:

In the Global Body Open Code section, paste the second GTM snippet. This <noscript> tag should be placed immediately after the <body> opening tag.

<!-- Google Tag Manager (noscript) -->
<noscript>
  <iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXXXXX"
  height="0" width="0" style="display:none;visibility:hidden"></iframe>
</noscript>
<!-- End Google Tag Manager (noscript) -->

Note:

Replace GTM-XXXXXXX with your actual GTM container ID.

Save Changes:

After inserting both snippets, click Save to apply the changes.

Verify GTM Installation

After adding the GTM code:

Use Google Tag Assistant: Install the Google Tag Assistant Chrome extension to verify that GTM is correctly installed on your site.
Check Source Code: Right-click on your website, select “View Page Source,” and ensure both GTM snippets are present in the correct locations.
