GEO (Generative Engine Optimization), also called AI SEO, is optimizing content to be cited and recommended in the answers of generative AI engines like ChatGPT, Google AI Overviews, Gemini and Perplexity — instead of just ranking in the classic list of blue links. The lever shifts from pure keywords toward citable, clearly structured answers and demonstrated authority.
SEO optimizes for positions in the results list. GEO optimizes to be named as a source in a generated answer. Both share the fundamentals — crawlability, relevance, authority — but GEO puts more weight on answer-first phrasing, unambiguous entities and structured data.
GEO doesn't replace SEO, it builds on it. Without a technically clean, authoritative site there is nothing reliable for the AI to cite either.
Answer directly in the first sentence (answer-first). Mark up content with Schema.org. Name entities — brand, products, people — unambiguously and link them via sameAs. Structure content so a model can cleanly extract and cite individual passages.
Keep facts current and verifiable. AI engines prefer sources that answer a question precisely and checkably rather than writing around it.
More and more searches end in an AI answer instead of on a website. If you don't appear there as a source, you lose visibility — even without losing rankings in classic search.
The advantage goes early to those who make their content citable and machine-readable now, while the field isn't yet crowded.
No. GEO builds on and complements SEO. A technically clean, authoritative site is the basis; GEO adds answer-first structure and machine-readable signals.
Through mentions and citations in AI answers, referral traffic from AI engines, and how well your brand is covered in generated answers on your core topics.
A big one. Schema.org makes meaning machine-readable and helps engines cite correctly — from FAQ through Product to Organization and Author.
