What makes a source visible inside AI answers?
An AI answer is composed for one user and never published as a ranked page, so there is no results page to inspect. The only observable evidence is the answer itself: which brands it names, in what terms, and which sources it attributes.
Across the runs we operate, the sources that keep showing up share three practical traits. They are reachable without JavaScript, so a crawler that does not render pages still reads the content. They are unambiguous about what the page is and who publishes it, which is what structured data is for. And they agree with the rest of the web about the same entity: an address, a product name or a claim that contradicts every other source is a weak citation candidate.
That is why DelveDeep separates owned sources from third-party ones in every report. A brand can rewrite its own pages; it can only respond to what a review site or a directory says about it.
