GEO vs SEO vs AEO: what's the difference, and is SEO dead?
Short answer: SEO aims to rank pages in search results. GEO (generative engine optimization) aims to be cited or named inside AI-generated answers such as ChatGPT search, Perplexity and Google AI Overviews. AEO (answer engine optimization) is an older industry term for being the direct answer (featured snippets, voice assistants) and is now often used to mean much the same as GEO. SEO is not dead. Google says there are no extra requirements for its AI features beyond normal Search eligibility, so SEO basics are the foundation that GEO builds on.

Why this question
On 15 November 2026, Google autocomplete for "geo vs seo" suggested vs aeo, reddit and 2026, and "is seo dead ai" returned several variants. In Korean, "geo seo 차이" and "aeo geo 차이" appeared. Upwork job titles regularly combine the terms ("GEO/AEO/AI SEO Expert Needed"). The 10 newest "AEO" titles appeared within 1.7 days of each other.
Where "GEO" comes from
The term was formalised in the paper "GEO: Generative Engine Optimization" by Aggarwal, Murahari, Rajpurohit, Kalyan, Narasimhan and Deshpande (Princeton University, IIT Delhi and independent researchers), published at KDD 2024. The authors describe generative engines as systems that gather and summarise information from multiple sources to answer queries, and they define GEO as a framework to help content creators improve their visibility in those responses. In their benchmark (GEO-bench) they report that some methods raised visibility by up to 40%, and that results varied by domain. That is a research result on their benchmark, not a promise for any one site.
"AEO" has no single official definition. Treat it as a marketing label and ask anyone selling it what they will actually check.
Side by side
| SEO | GEO / AEO | |
|---|---|---|
| Goal | Rank a page in a list of links | Be named or cited inside an AI answer |
| Where it shows | Google and Bing results pages | ChatGPT search, Perplexity, Google AI Overviews and AI Mode, Copilot |
| What decides access | Crawling and indexing (Googlebot, Bingbot) | The same, plus each AI search crawler (OAI-SearchBot, PerplexityBot), which you control in robots.txt |
| How you measure | Rankings, clicks, Search Console | Asking fixed buyer questions and recording who is named and cited; Google counts AI feature traffic in Search Console's "Web" type |
| Content that helps | Useful pages, internal links, structured data that matches the page | The same, with direct answers near the top of the page |
Is SEO dead?
The platforms' own documents say no:
- Google: "There are no additional requirements to appear in AI Overviews or AI Mode." A page must be indexed and eligible for a snippet, and the usual best practices apply (crawlable, textual content, internal links, matching structured data).
- OpenAI: ChatGPT search works with search providers and rewrites queries. Sites need to allow OAI-SearchBot to be shown in its answers.
- Perplexity: PerplexityBot is what surfaces and links sites in Perplexity results.
So the SEO basics (crawlable, indexed, clear pages) are still required. GEO adds AI-crawler access, answer-first writing, consistent facts across the web and a habit of checking what the assistants actually say.
Where to start
