GEO vs AEO at a glance
| Dimension | AEO | GEO |
|---|---|---|
| What it competes for | Being the direct answer | Being a cited source in an AI answer |
| The question | “Am I the answer?” | “Did the AI build its answer from my content?” |
| Where it shows up | Featured snippets, People Also Ask, voice assistants, answer boxes | ChatGPT, Perplexity, Gemini, Google AI Overviews |
| What you optimise | Concise, extractable answers; structured data; clear Q&A | Entity authority, citable facts, presence across trusted sources |
| How you measure | Snippet share, position zero, voice results | Share of citations in AI answers |
| Relation to SEO | Extends SEO with answer format | A layer on top of SEO for generative engines |
What AEO is
AEO, or Answer Engine Optimization, is optimising to be the direct answer to a question. It predates generative AI: it covers featured snippets, People Also Ask and voice search. The core is a concise, unambiguous answer an engine can lift and show, backed by clear structure and structured data.
What GEO is
GEO, or Generative Engine Optimization, is optimising to be referenced and cited inside answers that generative engines build. It isn't about one highlighted snippet but about being one of the many sources a model synthesises its answer from, which takes entity authority, citable facts and trust spread across many places on the web.
Where they overlap — and where they split
They overlap more than the acronyms suggest. Both reward content that's easy to extract, well structured and credible; clear answers to real questions fuel both. The difference is the goal: AEO wins when you're the one concise answer; GEO wins when you're one of the cited sources a longer, synthesised answer is built from. That's why AEO can often be solved at the page level, while GEO needs entity authority and presence across many places.
The line keeps blurring, because AI Overviews merge both worlds: they show a concise answer (AEO) built from cited sources (GEO). It's worth understanding both, because your outcome in AI depends on each.
Which should you prioritise?
Both stand on the same SEO foundation: without crawling, indexing and clear structure, neither works. The practical order: get SEO right and give concise, extractable answers to your customers' questions first (that supports AEO immediately), and in parallel build the entity authority and citable facts that let generative engines reference you (GEO). If you answer simple “how / how much / what is” questions, you'll see AEO pay off faster. If you're in a category where buyers research and ask AI for recommendations, GEO is the bigger lever. On most projects you do both, because they share the foundation.
FAQ
Frequently asked questions
AEO (Answer Engine Optimization) optimises you to be the direct answer — in featured snippets, voice assistants and answer boxes. GEO (Generative Engine Optimization) optimises you to be a source cited inside an AI-generated answer, such as ChatGPT, Perplexity or Google AI Overviews. In short: AEO wants to be the answer, GEO wants to be cited in an answer built from many sources.
It depends on how people search in your category. If you answer specific questions (how, how much, what is), AEO pays off fast. If you're in a category where buyers research and ask AI for recommendations, GEO matters more. In practice you do both, because they share the same foundation.
They overlap but aren't the same. AEO is older and broader — it covers any answer engine, including featured snippets and voice search, and focuses on one concise answer. GEO is newer and narrower — it covers generative engines and being one of many cited sources. Good AEO work often helps GEO, but GEO adds requirements around entity authority and citability.
No. Both sit on top of SEO — crawling, indexing, clear structure and authority are still required. GEO and AEO are layers on top of SEO that add answer format and citability; they're not a replacement for the technical and content fundamentals.
Start with solid SEO and clear, extractable answers to the real questions your customers ask — that supports AEO immediately. In parallel, build the entity authority and citable facts that let generative engines reference you. That combined discipline is exactly GEO / AI visibility.
