Duda
Add Monitoring to a Duda site from Site Settings > Header HTML.
On this page
Before you start
You'll need edit access to the site in the Duda editor.
Add the script
Open Header HTML
In the side panel, click More, then Settings, then Header HTML. (On an older site, this may instead be under SEO & Settings > Head HTML.)
Paste the script into Head HTML
In the Head HTML field, paste:
HTML <script src="https://accessible.so/a11y/loader.js" data-site-key="acc_rum_YOUR_SITE_KEY" async></script>Replace
acc_rum_YOUR_SITE_KEYwith your site's own key — copy the snippet from your domain's Monitoring page, which already carries it. Head HTML is printed inside<head>on every page of the site, so one paste covers the whole site.Publish
Save your changes, then republish the site — Head HTML changes don't reach the live site until you do.
Check it's working
See Debugging to confirm the script is reporting.
