Google Tag Manager WordPress Plugin


WordPress Google Tag Manager Installation

The Google Tag Manager is great for quickly tagging things as events, adding GA tracking tags, AdWords, DoubleClick, custom HTML, and more. There are many integrations that are easily set up. There is somewhat of a learning curve with using GTM but at least you won’t have to worry about adding the two tag snippets in the correct places on your site. Continue reading to learn just how easy it is to implement the GTM tag onto your WordPress installation.

Finding Your Google Tag Manager Tracking ID

Log into your GTM account > Click on your Account > Click on the Account ID (shown in the screenshot) > Find your Account ID.

Copy the whole thing. Example: GTM-PBVZ2BH

Add the Tag Manager Code to Your WordPress Site

Log into the back end of your WordPress installation. Click on “Red Olive” in the left sidebar > General Tab > Google Tag Manager > Check the box to enable the tag > Paste in your GTM Tracking ID > Click Save Changes.

Add the GTM hook to the header.php file

In your theme's header.php file add the following line:
<?php do_action( 'after_opening_body' ); ?>
immediately after the opening <body> tag.
NOTE: If your site uses a child theme, the header.php file may be found in the main theme directory or the child theme directory, or both. So, make sure to add the <?php do_action( 'after_opening_body' ); ?> code in any of the header.php files.

Via the WordPress Backend

In the back end of your WordPress site go here: Appearance > Editor > header.php and add the line right below the opening <body> tag.

***If WordPress will not allow you to edit this file you can install a theme editor plugin to make the change with a plugin like the following:


Navigate here:

wp-content/themes/YOUR THEME/header.php

Open the header.php file and add the line right below the opening <body> tag.

If you are unsure the of the name of your theme you can check it out in the WordPress back end by going to: Appearance > Themes > Find the Active Theme.

Verify that the GA Tag is on Your WordPress Site

View the page source of your website and search for your GTM tag ID (you probably still have it copied to your clipboard) to verify that the tag is installed. You could also use the Google Chrome Tag Assistant Browser Extension to see if it’s installed properly on your site.
