WordPress

The easiest way is a plugin that adds code to your site's head. Editing the theme directly works, but a theme update overwrites it.

StepsCopy Anchor Link

1. In the WordPress admin, go to Plugins → Add New Plugin and install WPCode (or Insert Headers and Footers), then activate it.
2. Open the plugin's header settings (in WPCode: Code Snippets → Header & Footer).
3. Paste the script tag below into the Header box.
4. Click Save Changes.

<script
  defer
  data-site="tkb_a1b2c3d4"
  data-domain="example.com"
  src="https://stats.example.com/js/tkb_a1b2c3d4.js">
</script>

Prefer code? Put this in the functions.php of a child theme instead of using a plugin. Do not paste it into the parent theme: an update removes it.

<?php // functions.php of your child theme
add_action('wp_head', function () { ?>
  <script
    defer
    data-site="tkb_a1b2c3d4"
    data-domain="example.com"
    src="https://stats.example.com/js/tkb_a1b2c3d4.js">
  </script>
<?php });

• A caching or optimisation plugin (WP Rocket, LiteSpeed, Autoptimize) can serve an old page or delay the script. Clear its cache, and exclude the script from delay or minify settings.
• A theme without a wp_head() call in header.php prints no head code. Most themes have it; if yours does not, use a different theme or ask its author.
• Block themes and page builders sometimes set their own head. The plugin route above still works with them.
