llms.txt
A proposed standard file (similar to robots.txt) that provides structured information about a website specifically for AI models and LLMs.
llms.txt is an emerging web standard that provides a structured, machine-readable file at a website's root (e.g., example.com/llms.txt) containing key information about the site specifically designed for consumption by large language models and AI systems.
Similar to how robots.txt communicates with web crawlers and sitemap.xml provides content structure, llms.txt offers AI models a concise overview of a website's purpose, key pages, products, services, and other relevant context. This helps AI systems more accurately understand and represent the site in generated responses.
Implementing llms.txt is a proactive AEO strategy because it gives brands direct control over how they present themselves to AI systems, reducing the risk of misrepresentation and increasing the chance of accurate, favorable AI mentions.
