If you want to add Microsoft Clarity tracking to your site, you will be asked to add some code to your site's  <head> tag.

The easiest way to do this is add a snippet that hooks to the wp_head action. Here's an example:

add_action( 'wp_head', function () { ?>

<script type="text/javascript">
    })(window, document, "clarity", "script", "XXXXXXXXXX");

<?php } );

Remember to replace XXXXXXXXXX in the code above with your actual project ID.
