Answer
SEO vs AEO vs GEO: what is the difference?
SEO optimizes where your pages rank. AEO optimizes whether AI answer engines extract and quote you. GEO optimizes whether generative AI names and recommends you. SEO is the foundation; AEO and GEO build on top of it.
The three, defined
- SEO - Search Engine Optimization
- Getting your pages to rank in the list of links a search engine returns. The base layer: crawlable, useful content with relevant links.
- AEO - Answer Engine Optimization
- Getting AI answer engines to extract and quote your content directly in their answers. Rewards content that cleanly resolves a specific question.
- GEO - Generative Engine Optimization
- Getting generative AI engines to name, cite, and recommend your business when buyers ask. Rewards consistent entity information and trusted third-party corroboration.
How they differ at a glance
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in links | Be quoted in answers | Be named and recommended |
| Surface | Search results page | AI answer extracts | AI recommendations |
| Wins on | Relevance + links | Clear, answer-shaped content | Entity clarity + corroboration |
They overlap more than they compete. The same foundations, crawlable and credible content, consistent entity information, and trusted third-party sources, earn all three.
Which do you need?
All three, run as one program. Keep your SEO foundation sound, structure content so AI can extract clean answers, and make sure your entity is consistent and corroborated so generative engines can confidently recommend you. The acronyms matter less than the outcome: when buyers ask AI about your category, do you appear, get cited accurately, and get recommended?

Frequently asked questions
What is the difference between SEO, AEO, and GEO?
SEO (Search Engine Optimization) is about where your pages rank in a list of links. AEO (Answer Engine Optimization) is about whether AI answer engines extract and quote your content in their answers. GEO (Generative Engine Optimization) is about whether generative AI names and recommends your business. SEO is the foundation; AEO and GEO build on it.
Do I need all three?
Practically, yes, because they share the same foundations: crawlable, credible, well-structured content with consistent entity information and third-party corroboration. You do not run three separate programs so much as one program that earns ranking, extraction, and recommendation at once.
Is AEO or GEO replacing SEO?
No. Search-grounded AI answers still rely on crawlable, credible content, and Google has said its AI features remain grounded in core search, so the SEO foundation still matters. What changes is that ranking alone no longer guarantees the buyer sees you, because the AI answer can decide before anyone clicks a link.
Does the terminology actually matter?
Less than the outcome. The acronyms describe overlapping tactics. The real question is simple: when buyers ask AI engines about your category, do you appear, get cited accurately, and get recommended? Optimize for that and the labels sort themselves out.
