WordPress
Two ways to add the script: a small snippet in your theme, or a header plugin if you prefer no code.
Option A — theme (functions.php)
In your child theme's functions.php, hook the script into wp_head:
add_action( 'wp_head', function () { ?>
<script defer src="http://localhost:3000/analytics.js" data-website-id="YOUR_TRACKING_ID"></script>
<?php } );Option B — header plugin
Use any "insert headers and footers" plugin, or your theme builder's custom-code area, and paste the plain snippet into the site head:
<script defer src="http://localhost:3000/analytics.js" data-website-id="YOUR_TRACKING_ID"></script>Caching plugins
If you use a caching plugin, clear the cache after installing so the updated <head> is served.
