llms.txt explained: the new standard for AI search

Short answer: llms.txt is a plain-text file placed at the root of your website (/llms.txt) that gives AI systems a concise, structured summary of who you are and what your most important pages are — similar to how robots.txt and sitemap.xml help search crawlers.

Why llms.txt exists

AI systems have limited context and often struggle to parse large, navigation-heavy websites. llms.txt offers a clean, curated entry point: a Markdown-formatted file that states what your business does and links to your key pages, so a model can understand you without crawling everything.

What goes in an llms.txt file

  • An H1 with your business or site name.
  • A short blockquote summarizing what you do.
  • Sections (Services, Capabilities, Process) with linked key pages.
  • Concise descriptions — facts over marketing language.
  • Contact details.

Does llms.txt actually help?

It is an emerging standard, not yet universally consumed by every engine. But it is low-cost, low-risk, and forward-looking: it documents your site clearly, and adoption is growing. Treat it as one piece of a complete GEO strategy, not a magic switch.

How to create one

Write a Markdown file following the structure above and serve it at https://yourdomain.com/llms.txt. Keep it current as your site changes. You can see a live example at our own llms.txt. We generate and maintain one for every client as part of our GEO-ready website and management services.
