Add Tracking Code in WordPress
July 12, 2023
Meta Pixel Code
The Meta Pixel is a snippet of JavaScript code that allows you to track visitor activity on your website. It works by loading a small library of functions which you can use whenever a site visitor takes an action (called an event) that you want to track (called a conversion).
Google Tag Manager
Google Tag Manager works by using a single JavaScript code snippet that you add to your site as a container for all the tags you want to manage.
<?php
function sw_custom_js()
{
echo '
<!-- Your Tracking Code -->
<!-- End Tracking Code -->';
}
// Add hook for admin <head></head>
add_action('admin_head', 'sw_custom_js');
// Add hook for front-end <head></head>
add_action('wp_head', 'sw_custom_js');
// Add Google Tag code which is supposed to be placed after opening body tag.
add_action( 'wp_body_open', 'wpdoc_add_custom_body_open_code' );
function wpdoc_add_custom_body_open_code() {
echo '<!-- Google Tag Manager (noscript) --><noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-J4LMVLR" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript><!-- End Google Tag Manager (noscript) -->';
}
