SEO vs AEO vs GEO: how to rank #1 in AI search
Quick answer
To rank in AI search you optimize three layers at once: SEO (rank in links), AEO (be the extracted answer), and GEO (be cited inside AI-generated responses). The fastest wins are answer-first content, FAQ and Organization schema, an llms.txt file, and authoritative citations — the exact gaps an AI visibility audit measures against the competitors AI already recommends.
Why AI search visibility matters now
Buyers increasingly ask an AI engine instead of scrolling a results page. ChatGPT serves hundreds of millions of weekly users, Perplexity answers hundreds of millions of monthly queries, and Google AI Overviews now appear on a large share of searches. When someone asks “what’s the best {your category}?”, one set of brands gets named — and the rest are invisible. AI Visibility Auditor measures whether that’s you across ChatGPT, Gemini, Claude, Perplexity, Google AI Overviews and beyond.
What is AEO (Answer Engine Optimization)?
AEO is the practice of structuring content so answer engines can extract and quote it directly. Where SEO targets a ranked list, AEO targets being the answer. The highest-leverage moves are FAQPage schema, answer-first writing (a direct 2–3 sentence answer before any marketing copy), and clear question-shaped headings that mirror how people actually ask.
What is GEO (Generative Engine Optimization)?
GEO is optimizing your brand to be included and cited in AI-generated answers from systems like ChatGPT, Perplexity and Google AI Overviews. GEO rewards entity clarity (Organization and sameAs schema), authoritative and data-rich content, structured data, an llms.txt file, and third-party mentions the models trust.

Common questions
What is AEO (Answer Engine Optimization)?
AEO is structuring your content so answer engines can extract and quote it directly as the answer. The biggest levers are FAQPage schema, answer-first writing (a direct 2–3 sentence answer before any marketing copy) and clear question-shaped headings.
What is GEO (Generative Engine Optimization)?
GEO is optimizing your brand to be included and cited in AI-generated answers from systems like ChatGPT, Perplexity and Google AI Overviews. It rewards entity clarity (Organization and sameAs schema), authoritative data-rich content, an llms.txt file and trusted third-party mentions.
What’s the difference between SEO, AEO and GEO?
SEO optimizes for ranking in a list of links, AEO optimizes for being the extracted answer, and GEO optimizes for being named and cited inside an AI-generated answer. Modern AI visibility means winning all three layers at once.
How do I rank #1 in AI search?
Audit how AI engines currently describe you, lead key pages with answer-first content and FAQ schema, strengthen your entity with Organization/sameAs markup and an llms.txt file, earn authoritative citations, then close the specific gaps where rivals are cited instead of you.
Does AEO or GEO replace SEO?
No — AEO and GEO build on SEO. You still need crawlable, authoritative pages; AEO and GEO add the structure and entity signals that let answer and generative engines quote and cite you, not just rank you.
