The same work as AEO under a name that emphasises the generated answer rather than the engine: being named and cited when ChatGPT, Perplexity, Gemini or AI Overviews write an answer to a buyer's question. In practice the terms are interchangeable, and the checklist is the same.
The one useful distinction
GEO as a term came from a 2023 research paper that tested which changes to a page made a generative engine more likely to quote it: adding statistics, citing sources, quoting authorities, plainer language. Those are page-level tactics. AEO as used by practitioners includes the off-site work too. This site uses 'AI visibility' for the measurement and describes the work plainly.
