SEO · AEO · GEO Explained

SEO. AEO.
GEO.

Three disciplines. One goal: make your business the answer people get, whether they search Google, ask ChatGPT, or prompt Perplexity.

AEO and GEO are the same thing under different names — AEO is the industry term, GEO is what researchers call it. Both describe getting your business cited by AI tools like ChatGPT, Perplexity, Google AI, and Claude.

The shift happening now

SEARCH IS NO LONGER
JUST GOOGLE.

In 2022, finding a business meant searching Google and clicking links. In 2026, people ask ChatGPT or Perplexity and get a direct recommendation. No search results page. No clicking. Just a name.

The business that gets recommended is the one that structured its content for AI. That's what AEO and GEO do. It's the new SEO — and most of your competitors haven't started yet.

Traditional search (SEO)

User types query. Google returns 10 links. User picks one to click. Your ranking and backlinks determine whether you appear.

AI answer engines (AEO / GEO)

User asks AI a question. AI cites 1-3 trusted sources and gives a direct answer. Your schema, FAQ structure, and entity signals determine whether you get named.

GEO

Generative Engine Optimization

Goal: Same as AEO — the research term

  • The academic name for AEO
  • Coined in a 2023 Princeton / Georgia Tech paper

📄

Where GEO came from

The term GEO was coined in a 2023 research paper titled "GEO: Generative Engine Optimization" by researchers at Princeton University, Georgia Tech, and The Allen Institute for AI. The paper defined the discipline of optimizing content for AI-generated answers — what the industry now calls AEO. Both terms describe the same work.

How AEO / GEO works

THREE THINGS THAT
GET YOU CITED.

01

Structure your content

AI tools don't read websites like humans do. They scan for schema markup, FAQ blocks, and clear question-and-answer patterns. We restructure your pages so AI can extract and cite your answers.

02

Signal authority

Citations come to businesses that look authoritative to AI. That means Organization schema, author markup, consistent NAP data, and content that answers specific questions better than anyone else.

03

Track and expand

We monitor whether ChatGPT, Perplexity, and Google AI are citing your business. Monthly reports show what's working, what competitors are doing, and where to expand next.

Common questions

What is Answer Engine Optimization (AEO)?

AEO is the practice of structuring website content so AI tools like ChatGPT, Perplexity, and Google AI cite your business when someone asks a relevant question. Instead of ranking on a search results page, you appear as a recommended answer.

What is GEO (Generative Engine Optimization)?

GEO is the academic term for the same discipline as AEO. The term was coined in a 2023 research paper by Princeton University, Georgia Tech, and The Allen Institute for AI. It refers specifically to optimizing content for generative AI outputs — ChatGPT, Perplexity, Google AI Overviews, and similar tools. In practice, GEO and AEO describe identical work: the signals, methodology, and outcomes are the same. The industry uses AEO; researchers use GEO.

Is GEO the same as AEO?

Yes. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are the same discipline under different names. GEO emerged from academic research in 2023. AEO is the term used by agencies and practitioners. Both refer to optimizing website content — schema markup, FAQ structure, llms.txt, entity signals — so that generative AI tools cite your business in their answers.

How is AEO different from SEO?

SEO gets your page to rank on Google so people click through to your site. AEO gets AI to recommend your business directly in its answer — often without the user visiting any site at all. You need both: SEO for search traffic, AEO for AI traffic. They use different signals and must be optimized separately.

Which AI tools does AEO / GEO affect?

ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot, and Claude. These tools are now the first place many people go to find a business or get a recommendation. If you're not being cited there, you're invisible to a growing share of your market.

How long does it take to see citations?

Most businesses begin seeing first AI citations within 9-12 weeks of publishing AEO-optimized content with proper schema markup in place. Initial citations appear for specific long-tail queries first, then build into broader coverage as AI systems develop more confidence in your content.

Do I need AEO if I already rank well on Google?

Yes. Google rankings don't automatically translate to AI citations. The two systems use different signals. Many businesses with strong Google rankings have zero AI visibility, and vice versa. AEO is a separate discipline that requires its own optimization strategy.

How do I know if my business is being cited by AI?

The fastest manual test: open ChatGPT or Perplexity and ask 'best [your service] in [your city]'. If your business name does not appear, you are not being cited. For ongoing tracking, the Apex Radar AI Visibility Monitor runs these checks weekly across four AI tools and reports exactly where you appear, who gets recommended instead, and what AI says about you.
