Generative Engine Optimization: Optimizing to Be Cited, Not Ranked
GEO aims at being selected and cited inside an AI-generated answer rather than ranked in a list of links; the founding research found that citations, quotations, statistics and authoritative phrasing help, while keyword stuffing does not.
Generative Engine Optimization (GEO) is the practice of making content more likely to be selected and cited inside an AI-generated answer, rather than ranked within a list of links. The term was formalised in a 2023 paper by Pranjal Aggarwal and co-authors, which framed it as an optimisation problem over content features and measured which changes actually moved citation rates. The structural difference from SEO is what counts as a result. A search engine returns ranked documents and the click is the prize; a generative engine synthesises a single answer from several sources and cites some of them. Visibility becomes a question of whether material is quotable and safely attributable, and how prominently it surfaces inside a synthesised passage rather than at what position on a page. The reported findings are worth stating precisely, since they get overstated downstream: - Features associated with better citation include authoritative phrasing, explicit citations, direct quotations and concrete statistics — the markers of something a model can attribute with confidence. - Keyword stuffing, the classic and long-degraded SEO tactic, performs poorly against generative engines. - Length, uniqueness and presentation affect how much of a cited source actually appears in the answer, so a citation is not uniformly valuable. Two cautions. First, most published GEO guidance is vendor material rather than replicated measurement, and generative engines change retrieval and citation behaviour without notice, so advice ages faster than its SEO equivalent did. Second, the tactics that genuinely help overlap heavily with writing clear, well-sourced, factually dense material — a strategy that predates the acronym. Answer Engine Optimization (AEO) is used broadly interchangeably with GEO in industry writing, with no stable distinction between the two.
