More about llms.txt File
llms.txt File is a proposed web standard that involves placing a markdown file named llms.txt at the root of a website. This file serves as a guide for large language models (LLMs), offering a concise and structured overview of the site's content. The primary goal is to enhance the ability of AI systems to understand and interact with the website's information effectively. The llms.txt file typically includes:
# Title
> Optional description goes here
Optional details go here
## Section name
- [Link title](https://link_url): Optional link details
## Optional
- [Link title](https://link_url)
To generate an llms.txt file for your website, you can use the SiteSpeak llms.txt generator.
By implementing an llms.txt file, website owners can facilitate more accurate and context-aware responses from AI assistants, improving user experience and information retrieval. This standard complements existing web standards like robots.txt and sitemap.xml by focusing specifically on enhancing AI comprehension of web content. For more details, visit llmstxt.org.
Google's position on llms.txt (May 2026)
It is worth being clear about one thing: Google has explicitly stated that they do NOT read or require llms.txt files for AI Overviews or AI Mode. In their May 2026 AI Optimization guide, Google wrote: "You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in generative AI search."
Google relies on the same Googlebot, the same index, and the same ranking signals as regular Search. Where llms.txt still has value is with AI systems and AI agents that do read it, including some retrieval-focused tools and developer-facing AI products. Treat it as a "nice to have" for those audiences, not a requirement for Google AI surfaces.
