Page
A page is one web address, such as a single article or product page, as opposed to the whole website it sits on.
A page is a single address on the web: one article, one product page, one review, one forum thread. The website it sits on is its domain. kestrelroasters.example/guides/grinders is a page, and kestrelroasters.example is its domain.
The difference matters in AI search because the platforms read pages, one at a time. When an answer uses a source, it used a particular page, with particular words on it. That's the thing you can read, and the thing someone can change.
Why the page is the unit that counts
A whole site rarely gets you named. One page on it does. A food magazine might publish hundreds of articles, and only one of them, its list of the best coffee subscriptions, is the page the platforms keep reading when someone asks about subscriptions.
For example, say the answers to your prompts used goodfoodguide.example 60 times this week. That sounds like one big source. Look at its pages and you may find 45 of those uses came from a single list article that names Kestrel Roasters and Harrow & Pine but not you. That one page is where your work goes: ask the editor to look at you, or make the case for being on the list.
Pages on your own site
The same goes for your website. The platforms don't read your site as a whole. They read the page that best matches what they searched for, and sometimes only part of it. A strong home page won't help if your pricing page is the one they read, and it's out of date.
So when you're working on being named for a prompt, the useful question is which page should answer it, and whether that page does.
Pages in AnswerOrbit
The Pages tab in Sources lists every single page the answers used, with how many answers used it, how many times it was linked, and its type, like a list article, a comparison or a directory profile. Page checks in Recommendations test one of your pages against a prompt.
