llms.txt: Google Says Search Ignores It, Yet Uses It Itself
Google's AI search guide says llms.txt isn't needed and Search ignores it, while its own teams use it and a 137K-site study finds 97% go unread.

Google search optimization is the practice of shaping websites, content, and technical infrastructure so pages are discovered, understood, and surfaced by the world's dominant search engine. For years that meant keywords, links, and page speed. Today generative AI is redrawing the discipline, and the rules marketers, publishers, and developers relied on are shifting quickly.
Search results increasingly answer questions directly. AI-generated summaries now appear above traditional links for a growing share of queries, including searches for specific brands, and more sessions end without a click to any website. That changes how traffic, attribution, and revenue flow across the web. Google also keeps refining its spam policies through recurring algorithm updates that target low-value, mass-produced content, including material churned out by AI tools.
A new vocabulary has emerged alongside these changes. Answer engine optimization (AEO) and generative engine optimization (GEO) describe efforts to get content cited inside AI responses. Software vendors have rushed to serve this demand, while Google maintains that the fundamentals of good SEO still apply. Questions about how publishers are compensated when their work feeds AI answers add an economic dimension to the debate.
