AEO vs GEO vs SEO: what’s the difference?
Last updated: June 12, 2026
TL;DR
SEO gets you ranked in a list of links. AEO (Answer Engine Optimization) gets you cited in answer features — AI Overviews, Perplexity, snippets. GEO(Generative Engine Optimization) gets you surfaced inside generative answers like ChatGPT and Claude. AEO and GEO overlap so much most people use them interchangeably. You don't pick one — good fundamentals serve all three; the AI layer just adds new failure modes (crawler access, JS rendering, structure) on top.
The three terms, in one line each
| Term | Optimizes for | The win |
|---|---|---|
| SEO | Ranking in a list of links | A blue link on page one |
| AEO | Answer features (AI Overviews, snippets, Perplexity) | Being the cited answer |
| GEO | Generative LLM responses (ChatGPT, Claude, Gemini) | Getting recommended inside the answer |
If you want the longer definitions and every adjacent acronym (LLMO, AI SEO), the 2026 glossary has them. This post is about the differences and what to do about them.
Where they overlap (and where they don't)
Most of the foundations are shared: crawlable pages, fast load, clear structure, genuinely useful content. That's why some practitioners shrug and say “it's all just SEO.” They're half right — and half wrong. The AI layer introduces failure modes classic SEO never had to think about:
- Different crawlers. GPTBot, ClaudeBot and PerplexityBot — not Googlebot. You can rank #1 on Google and be invisible to ChatGPT because a different bot, with different rules, never got in. See is Cloudflare blocking your AI crawlers.
- JavaScript rendering.Most AI crawlers fetch raw HTML and don't wait for client-side rendering, so content that's great for a browser can be empty to a model.
- Extraction over ranking. AEO/GEO reward answer-shaped content a model can lift cleanly and attribute — not just keyword-matched pages.
When each one matters most
SEOstill drives the majority of web traffic — it's not going anywhere, and it's your base. AEO/GEO matter more every quarter as answers replace clicks: when an AI summary appears on a Google result, click-through on the links drops sharply (Pew Research found it roughly halving), so for informational queries the citation isthe visibility. If your buyers ask ChatGPT or Perplexity for recommendations in your category, AEO/GEO is no longer optional.
Do you need all three?
You don't run three separate programs — you run one, with an AI-visibility layer on top. Keep doing solid SEO. Then make sure the AI crawlers can reach you, that your content is in the raw HTML, and that it's structured enough to quote. That layer is exactly what AEO and GEO describe. Our guide to Answer Engine Optimization walks through it, and an audit shows you which parts are failing on your own site.
FAQ
Is AEO the same as GEO?
They're close enough that most people use them interchangeably. The cleanest split: AEO targets answer features (AI Overviews, snippets, Perplexity answers); GEO targets being surfaced inside generative responses (ChatGPT, Claude, Gemini). In practice the work is the same — make your site reachable, readable and quotable by AI.
Is AEO/GEO just SEO with a new name?
The fundamentals overlap heavily, so good SEO helps. But the crawlers, the no-JavaScript rendering, and the focus on extractable answers are genuinely different — and they're why a top-ranked page can still be invisible to ChatGPT. It's SEO plus a new technical layer, not a rebrand.
Should I stop doing traditional SEO?
No. Google search still sends most web traffic, and the SEO fundamentals feed AEO/GEO too. Add the AI-visibility layer on top — don't trade one for the other.
