AI Visibility refers to how prominently and consistently a brand appears in AI-generated responses across answer engines.

AEO refers to the practice of structuring content so that AI answer engines can extract and surface it in response to user questions.

It involves optimizing the text layer of content — titles, descriptions, transcripts, chapter markers — so AI systems can identify, extract, and cite it when relevant.
