Add the selector to any website

If your platform is not listed, this works anywhere you can edit your site's HTML or add a site-wide code snippet.

Where the snippet goes

1. Copy the snippet from Settings, then Selector, in your project. The Copy button sits next to it. Use that one: it already carries your project's identifier.
2. Find where your site defines the shared head of every page. Depending on your setup that is a layout template, a header include, or a setting whose description mentions custom code, code injection, or head HTML. The wording differs on every platform, so look for the one that applies to the whole site rather than to a single page.
3. Paste the snippet just before the closing </head> tag, or into the head box of that setting.
4. If you are asked which pages, choose all of them. If you are asked head or body, either works, head is preferred. If you are asked whether the code runs again on every page change, either answer works: the script notices page changes itself and re-attaches the selector, so take whichever your builder suggests.
5. Save, then publish. Where a platform separates the two, nothing reaches visitors until you publish.

The selector then appears on every page that uses that shared head.

The trap on any website

Pasting into a page-level HTML block instead of the site-wide setting.

It looks like it worked on the page you were editing, and the selector is missing everywhere else. It is often worse than that: many builders render an embed block inside a frame of their own, so the snippet only ever sees that little box and never your real page. Then the selector appears nowhere at all, including the page you pasted it on.

If your platform offers both, always choose the site-wide code setting or the shared template. If it offers only page blocks, the snippet route is not available to you, and the other delivery option (we serve your original pages and inject the selector ourselves) is the way in.

How to know it worked

Open your published site, view the page source, and search for ut/v1.js. One match means it is live. Check the published site, not the editor preview.

Then open Settings, then Selector, and run Check my site under "Is the snippet on your site?". It asks your site directly and answers plainly, so you are not relying on your own reading of the source.

A red result straight after publishing usually means not yet, rather than failed. Your platform, your CDN or a caching plugin can keep serving the page it built before you pasted. Give it a few minutes, clear your site's cache if you have one, then use Check again.

Once the tag is confirmed, your settings changes reach the live site within about five minutes, or immediately with Clear the cache on the same screen.
