Cited domain
A cited domain is a website, counted as a whole, that an AI answer links to as one of its sources.
A cited domain is a website, taken as a whole, that an AI answer links to as a source. If an answer links to three articles on the same food magazine's site, that magazine's domain is one cited domain, linked three times.
Looking at domains shows you which websites hold sway in your category. Single pages come and go, but a review site or a forum that's cited week after week is a place the platforms trust for your subject.
Pages or domains?
Use both. Domains tell you which sites matter. Pages tell you what to do about it: which article to get into, which listing to fix, which thread to answer.
For example, Harrow & Pine looks at a week of answers and sees that one review site appears in 30 of them, spread over 12 different pages. No single page stands out, but the site does. That's where to focus, starting with the pages that name its competitors.
Your own domain
Your own domain belongs in the list too. If your site is cited often, the platforms are reading you. If it's cited and you're still not named in the same answers, the platform used your page and recommended someone else, which usually means the page doesn't make your case clearly enough.

Sources sorts every source by who owns it: your website, then your other domains, then your competitors' domains, then everyone else, grouped by type. The Domains tab lists every website the answers used, with how many answers used it and how many times it was linked. If a domain is in the wrong group, you can change it.
