The value must match exactly. No protocol, no trailing slash. ## Platform guides The snippet works on any site that serves HTML. Common setups: | Platform | Where to add the snippet | | ----------- | ----------------------------------------------------------------------- | | Plain HTML | Before `` in your HTML file | | WordPress | Appearance > Theme Editor > `header.php`, or use a header/footer plugin | | Webflow | Project Settings > Custom Code > Head code | | Shopify | Online Store > Themes > Edit code > `theme.liquid` | | Next.js | `pages/_document.js` or `app/layout.tsx` `` section | | Squarespace | Settings > Advanced > Code Injection > Header | ## Single-page applications For React, Vue, Angular, and other client-side routing frameworks, add the `data-spa="auto"` attribute so GhostlyX tracks route changes automatically: ```html theme={"dark"} ``` ## Privacy No cookies are set. No personal data is collected. The script does not use localStorage or fingerprinting of any kind. You do not need a cookie consent banner for the GhostlyX script. ## Verify installation 1. Open your site in a browser. 2. Open the GhostlyX dashboard and go to the **Real-time** tab. 3. Within 60 seconds you should see your visit counted as an active visitor. If you do not see data after 60 seconds, check that the `data-domain` value matches the domain in your site settings exactly, and that the script tag is present in the rendered HTML (not just the source template).
