Search is no longer only ten blue links. Google AI Overviews, AI Mode, ChatGPT Search, and Perplexity cite pages — or they don't. These articles cover GEO, llms.txt, ChatGPT site-scoping, and the SEO fundamentals Google still says are the foundation for generative AI features.

GEO is the practice of making pages easy for AI answer engines to retrieve, quote, and cite — not just rank as a blue link. Google’s own guidance is that AI Overviews and AI Mode use the same core ranking systems as Search, so helpful, crawlable, people-first content is the foundation. Extra machine-readable files (llms.txt, Markdown alternates) help other engines; Google Search does not require them.
The page must be indexed and eligible for a snippet in Google Search. There is no extra AI-only markup. Google’s 2026 generative-AI guide says to keep doing foundational SEO: crawlable HTML, unique non-commodity content, good page experience, and structured data that matches visible text. Query fan-out means one thorough page can support several related questions.
No. Google has said it does not use llms.txt (or similar AI-only files) for Search or generative AI features. Other engines (ChatGPT, Claude, Perplexity) may still fetch it. Keep llms.txt accurate if you publish one, but do not treat it as a Google ranking lever.
Discover is interest-based, not keyword-based. Indexed, people-first articles can appear without extra tags. Google recommends large images (at least 1200px wide, more than 300,000 pixels), max-image-preview:large, a representative og:image that is not a generic logo, and titles that describe the content without clickbait.
