AEO vs. GEO vs. LLMEO vs. SEO (2026)
Four names for substantially the same practice, each emphasizing a different corner: AEO the answer surfaces, GEO the generative architecture (the research literature's term), LLMEO the model doing the answering, and SEO the three-decade-old parent discipline of ranked search. The work — retrievable, trustworthy, citable content — is shared.
The distinctions that hold up: SEO optimizes a document's position in a ranked list, and its center of gravity — crawlability, structure, authority — remains the base layer every other acronym builds on. AEO and GEO both describe optimizing for composed answers; AEO is the practitioner's word, GEO the academy's, entering use through a 2023 research paper. LLMEO is the least standardized and usually folds into the other two.
The honest answer to which term is correct: the market has not decided, and may never — the surfaces keep multiplying faster than the vocabulary settles. This publication's name, Anything Engine Optimization, is a position on exactly that churn.
Common questions
Is GEO the same as AEO?
Near enough that the terms are used interchangeably: GEO comes from the research literature, AEO from practice, and both describe making content visible and citable in AI-generated answers.
What is the difference between SEO and GEO?
SEO optimizes position in a ranked list of links; GEO optimizes retrieval and citation inside a composed AI answer. SEO's fundamentals remain the base layer GEO builds on.
What is the difference between AEO and SEO?
SEO earns a ranked link on a results page; AEO earns a place inside the answer an AI engine writes. The work overlaps — pages that can be retrieved, trusted and cited — but the scoreboard differs: rank and clicks for SEO, citations and mentions for AEO. Ranking well doesn't guarantee the second: in a University of Toronto study, 97% of the pages ChatGPT's own search retrieved weren't in Google's top 50 for the same queries.
What are AEO and GEO in digital marketing?
Two names for optimizing content so AI engines use it in their answers. AEO (answer engine optimization) is named for the answer surfaces, such as ChatGPT, Perplexity and Google's AI Overviews; GEO (generative engine optimization) is the research literature's term. In practice they describe the same work.
