Install on WordPress
Pick whichever matches how your site is built. All three put the same tag in the page <head>.
Option 1: a header-snippet plugin (simplest)
Install a plugin such as "WPCode" or "Insert Headers and Footers". In its Header section, paste:
<script defer src="https://kymo.in/beat.js" data-site="yoursite.com"></script>Save. This applies site-wide with no theme edits.
Option 2: a block theme
In the admin, go to Appearance, then Editor, then Patterns or the template's header, and add a Custom HTML block containing the tag. Block themes vary — the header-snippet plugin is more reliable if you are unsure.
Option 3: a classic theme
Edit your theme's header.php and paste the tag immediately before </head>. Use a child theme so a theme update does not overwrite it.
Then verify events arrive.
