A visible citation is when the AI displays or separately reports the page as a source. Not every retrieval includes a citation—the reporting keeps discovery, retrieval, and referral separate so signals don't get inflated. If you see a retrieval with a citation or a confirmed referral, that's stronger, but it's not proof of interest or a sale. Interpret signals over time rather than drawing conclusions from a single event.
A customer may receive a useful AI answer without ever clicking through to the website.
