What Is LLMs.txt? The Guide To AI Search & GEO

Summary

In this episode Jennifer Baker explains the emerging llms.txt standard and its role in Generative Engine Optimization (GEO), a new approach to making e‑commerce sites readable for AI agents like ChatGPT, Claude, and Perplexity. She outlines how a simple Markdown file at the site root serves as a "sitemap for AI," providing clean, token‑efficient data that improves accuracy and reduces hallucinations when models retrieve product information. The show highlights early adopters such as Vercel, Stripe, and Anthropic, and offers a step‑by‑step guide for auditing content, automating file generation, and maintaining the file to keep pricing and policies up to date. Finally, Baker discusses the broader business impact, including AI‑driven referral traffic and the future of interactive AI protocols.
