What is llms.txt and why does it matter?

llms.txt is a standard file (similar to robots.txt) that serves an LLM-friendly Markdown summary of your website at the /llms.txt URL. It helps AI systems like ChatGPT, Google AI, and other large language models discover and understand your site content. Jay’s SEO Checklist can dynamically generate this file from your pages, posts, FAQs, and custom post types. You can customize the content, exclude specific posts, configure caching, and add custom Markdown sections. It’s an emerging standard for AI discoverability.
