FAQ
Three questions people ask first
What is the AI SEO Shift?
The AI SEO Shift is the move from optimizing for blue-link rankings to optimizing for AI answer citations. It combines classical SEO (Google rankings) with AEO (Answer Engine Optimization) for ChatGPT, Claude, and Perplexity, and GEO (Generative Engine Optimization) for Google AI Overviews. Brands that adapt get cited inside AI answers; brands that do not lose visibility as users stop clicking through to websites.
What's the difference between SEO, AEO, and GEO?
SEO optimizes content to rank in Google’s organic results. AEO (Answer Engine Optimization) optimizes content to be cited inside answers from ChatGPT, Claude, and Perplexity. GEO (Generative Engine Optimization) optimizes content to appear in Google AI Overviews and Gemini. All three are needed in 2026: they share fundamentals like structured content and E-E-A-T, but differ in format, citation mechanics, and measurement.
How do I get cited by ChatGPT, Claude, and Perplexity?
AI engines cite content that is structured, authoritative, and unambiguous. Five high-leverage moves: (1) add direct one-paragraph answers under every H2; (2) implement FAQ, HowTo, and Organization schema; (3) include cited statistics and named entities; (4) maintain consistent author bylines and E-E-A-T signals; (5) ensure your robots.txt and llms.txt explicitly allow assistant crawlers.
