/llms.txt Machine Index
Publishing a root /llms.txt and /llms-full.txt file strips away noisy DOM wrappers and feeds AI agents a clean Markdown map of your product specs, pricing, and docs.
RAG pipelines split pages into 300–500 token chunks. Question-based H2/H3 headings followed immediately by a concise 40–60 word direct answer maximize vector similarity scores.
Rich JSON-LD (Organization, FAQPage, SoftwareApplication, and sameAs Wikidata/GitHub/LinkedIn links) anchors your brand inside LLM Knowledge Graphs.
Princeton & Georgia Tech GEO research shows pages containing verifiable statistics, numbers, comparison tables, and outbound citations earn up to 40% higher LLM visibility.
AI crawlers enforce strict token budgets per URL. Semantic HTML5 tags (<main>, <article>, <table>) ensure your core content isn't truncated by inline JS bloat.
