# 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.

**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.
