SEO, AEO, and GEO are three names for one job with three different finish lines. SEO (search engine optimization) earns a ranked link people click. AEO (answer engine optimization) earns the direct answer in a snippet or AI answer box. GEO (generative engine optimization) earns a citation inside an AI-generated answer. Same authority signals underneath, different win condition on top.
AEO vs SEO vs GEO at a glance
| SEO | AEO | GEO | |
|---|---|---|---|
| Full name | Search engine optimization | Answer engine optimization | Generative engine optimization |
| Goal | Rank a link | Win the direct answer | Get cited in a generated answer |
| Where it shows | Google, Bing organic results | Featured snippets, voice, AI answer boxes | ChatGPT, Perplexity, AI Overviews, Copilot |
| Win condition | Position on the page | Being read as the answer | Being the source the model quotes |
| Core metric | Rankings, clicks | Answer/snippet ownership | Citations, share of AI answers |
| Origin | 1990s onward | Featured-snippet and voice era | Princeton GEO paper, 2023 |
| Foundation | Authority, relevance, crawlability | The same | The same |
The last three rows carry the real message: the foundation does not change. Every one of these engines reads the same web, rewards the same authority, and ignores the same thin content.
What SEO optimizes for
SEO is the original discipline. You optimize a page so it ranks in the organic results, and a searcher clicks through to your site. The unit of success is a position, and the payoff is a visit. Everything else here sits on top of it, not instead of it. Rankings still feed the AI surfaces: AI Overviews and ChatGPT's web mode pull heavily from pages that already rank.
What AEO optimizes for
AEO predates the LLM boom. It grew out of featured snippets and voice assistants, when winning "position zero" meant your sentence got read aloud or pulled into Google's answer box instead of clicked. The target is the direct answer. You structure content so a machine can lift a clean, correct response: answer the question in the first breath, use question-shaped headings, add FAQ markup. Our AEO explainer goes deep on the tactics. The short version is that AEO optimizes to be the answer, not the tenth blue link.
What GEO optimizes for
GEO is the newest label. The term comes from a 2023 Princeton-led paper (Aggarwal et al., accepted to KDD 2024) that coined "generative engine optimization" and tested how content changes affect visibility inside AI answers. The target is a citation. You want the model to quote or paraphrase your page when it generates a response in ChatGPT, Perplexity, or Google AI Overviews. The study found that adding relevant statistics, citing sources, and including quotations raised a page's visibility in generative answers by up to 40%. Keyword stuffing did almost nothing.

Are AEO and GEO the same thing?
Mostly, yes. In practice they describe the same work with different emphasis. AEO comes from the answer-box world and leans toward direct, extractable answers. GEO comes from the LLM world and leans toward citations across multiple generative engines. The on-page moves overlap almost completely: clear answers up front, real numbers, cited sources, clean structure, earned authority. Different consultants pick different acronyms; the actual to-do list barely moves. SEO is the one that stays genuinely distinct, because it still targets a clickable ranking rather than an answer.
What does Google say about all this?
Google collapsed the distinction on purpose. Its 2026 guide, "Optimizing your website for generative AI features on Google Search," states that "from Google Search's perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO." The same document says you do not need llms.txt files, special schema.org markup, AI-specific rewrites, or content chunked into tiny pieces. Google's own guidance, in other words, treats AEO and GEO as SEO wearing new hats.
Which one should you actually do?
All three, because they are one program. Run the SEO foundation: crawlable, authoritative pages that earn backlinks and rank. Layer AEO on top by answering questions cleanly and marking them up. Layer GEO on top of that by making your best claims quotable and sourced. If you already run a disciplined content operation, including programmatic SEO at scale, none of this is a rebuild. The genuinely new part is measuring who cites you across engines, and our LLM SEO guide plus our roundup of AI SEO tools cover how.
