Quick Definition
llms.txt is an emerging web standard (similar to robots.txt) that provides AI systems with structured information about a website's content, expertise, and preferred citation formats. It helps AI crawlers understand and cite content correctly.
Why It Matters
llms.txt is an emerging standard (similar to robots.txt) that tells AI systems how to interact with your website content. It provides metadata about your site structure, key pages, and content organization, helping LLMs understand and accurately reference your content.
Real-World Example
An Indian SaaS company creates a llms.txt file specifying: their product pages, pricing, documentation structure, and key blog articles. When an LLM encounters their site during search, it can quickly identify the most relevant and authoritative pages to cite.

Presence -- llms.txt enhances your presence in AI search by making your site structure explicit and machine-readable. It helps AI systems find and reference the right content from your site.
Pro Tip
Create a llms.txt file at your domain root (example.com/llms.txt). Include: site description, key pages with descriptions, content categories, and update frequency. Keep it concise and well-structured. Update it when your site structure changes.
