SEO vs AEO vs GEO: How to Rank in Google, AI Overviews and ChatGPT in 2026
The difference between SEO, Answer Engine Optimization and Generative Engine Optimization — and a five-step plan to get your brand cited by ChatGPT, Gemini and Google AI Overviews.
Short answer: SEO gets you ranked in Google’s list of links. AEO (Answer Engine Optimization) gets your content picked as the direct answer in featured snippets, voice search and Google AI Overviews. GEO (Generative Engine Optimization) gets your brand mentioned and cited inside answers written by AI assistants like ChatGPT, Gemini, Perplexity and Copilot. In 2026 you need all three.
What is SEO?
Search engine optimization improves how your website ranks in traditional search results. It covers technical health (speed, crawlability, indexation), on-page relevance (titles, headings, content that matches search intent) and authority (links and mentions from other sites). SEO is still the foundation: AI answer engines lean heavily on pages that already rank well.
What is AEO (Answer Engine Optimization)?
AEO structures your content so a search engine can lift a passage and present it as the answer — in featured snippets, “People also ask” boxes, voice assistants and Google AI Overviews. The core rules:
- Put a direct, self-contained answer in the first 40–60 words of a page or section.
- Use question-style headings that match how people actually ask.
- Break steps and comparisons into lists and tables.
- Add FAQPage, HowTo, Organization and Service schema markup.
What is GEO (Generative Engine Optimization)?
GEO is about being recommended by generative AI. When someone asks ChatGPT “who is the best Google Ads agency for dental clinics?”, the model assembles an answer from what it has learned and what it retrieves from the web. GEO increases the chance your brand is in that answer.
- Entity clarity: one consistent name, description, address and set of services across your website, Google Business Profile, LinkedIn, directories and review platforms.
- Citations on trusted sources: reviews, industry directories, interviews and publications that AI systems already trust.
- Specific, quotable facts: numbers, results and definitions an AI can cite — vague marketing copy rarely gets quoted.
- Crawler access: let AI crawlers read your site and publish an llms.txt file that summarises your key pages.
