Wix lets you inject custom scripts site-wide through the Marketing & SEO → Custom Code panel — no code editor needed.
After signing up, copy your API key from your Findables dashboard.
In your Wix dashboard, go to Marketing & SEO → Marketing Tools → Custom Code.
Click + Add Custom Code in the top right.
In the code box, paste the following. Set the placement to Head and apply it to All Pages.
Replace YOUR_API_KEY with your API key and YOUR_SITE_SLUG with your site slug — both are in your dashboard.
Click Apply, then Publish your site. The script will now run on every page.
Pages will start appearing in your Findables dashboard as visitors load them.
