Practical Guide to /llms.txt and /llms-full.txt in the Site Root

Learn how to use the llms.txt standard to provide structured text summaries directly to large language model crawlers.

In the generative era, your site is read by AI crawlers as much as human visitors. To ensure these bots capture your business services accurately, you should publish an /llms.txt file. This is a plain text Markdown file detailing who you are, what you offer, and linking to your key pages.

When deploying llms.txt for local business websites, we recommend creating both a /llms.txt and a comprehensive /llms-full.txt (which hosts full clean text exports of all key content). This allows ChatGPT and Claude to ingest credentials, service details, and expertise without having to scrape noisy HTML layouts, leading to accurate citations in AI search interfaces.
