# Your Site Name ## About This File This llms.txt file provides AI-readable information about this website. It follows the llms.txt specification to help AI engines understand the site structure and content.
How to use
Save this file as llms.txt and upload it to your domain root so it is accessible at https://yourdomain.com/llms.txt. AI crawlers will check this file to understand your site's purpose and structure.
What Is llms.txt?
The llms.txt file is a proposed web standard that gives AI language models structured information about your website. It is similar in concept to robots.txt (which tells crawlers where they can go) and sitemap.xml (which lists your pages), but llms.txt tells AI what your site is about and which content matters most.
The file uses a simple Markdown-like format and sits at your domain root. When an AI crawler visits your site, it can read llms.txt to quickly understand your site's purpose without needing to crawl and interpret every page. This is especially valuable for large sites where AI crawlers might not index everything.
The llms.txt specification was proposed in late 2024 and has gained traction throughout 2025 and 2026 as AI search has grown. While not yet a formal W3C standard, it is being adopted by forward-thinking websites as part of their AI search optimization strategy.
Key Point
llms.txt complements robots.txt. While robots.txt controls access (can the AI crawl your site?), llms.txt provides context (what should the AI know about your site?). You should have both for complete AI search optimization.
Why llms.txt Matters for AI Search
Guides AI Understanding
Without llms.txt, AI engines must crawl your entire site and infer what it is about. With llms.txt, you explicitly state your site's purpose, target audience, and core topics. This reduces misinterpretation and increases the chance of being cited for relevant queries.
Highlights Key Content
AI crawlers have limited time and resources. llms.txt lets you point them to your most important pages first. This ensures your best content gets indexed and prioritized, rather than leaving it to chance which pages the crawler discovers.
Signals AI Readiness
Having an llms.txt file signals to AI platforms that your site is prepared for AI interaction. Early adopters of web standards tend to benefit disproportionately. Sites that had robots.txt and sitemaps early in SEO history gained advantages that compounded over time.
Easy to Implement
Unlike complex schema markup or content restructuring, llms.txt is a simple text file you can create in minutes and upload to your server. There is almost no technical barrier and no risk — it only helps, never hurts.
The llms.txt Specification
The llms.txt file follows a simple, human-readable format based on Markdown. Here are the key elements:
Title (Required)
The first line should be an H1 heading with your site or organization name. Use # Your Site Name format.
Description (Recommended)
A blockquote providing a brief description of your site. Use > Your description here format. Keep it to 1-3 sentences that capture what your site does and who it serves.
Key Pages (Recommended)
A list of your most important pages using Markdown links. Format: - [Page Title](URL): Brief description. Include your 5-15 highest-value pages.
Contact Information (Optional)
Contact details for your organization. Helps AI engines verify site ownership and authority.

Frequently Asked Questions
Is llms.txt required for AI search visibility?
No. llms.txt is optional and complementary to other AI search optimization techniques. Your content can still appear in AI search results without it. However, having an llms.txt file provides additional context that can help AI engines better understand and prioritize your content.
Is llms.txt the same as robots.txt?
No. They serve different purposes. robots.txt controls crawler access (what can be crawled). llms.txt provides context and guidance (what your site is about and what is most important). You should have both.
Which AI platforms support llms.txt?
The llms.txt specification is still emerging and adoption varies. Major AI platforms are aware of it, and some (including Anthropic's Claude) have expressed support. Even without formal platform adoption, having a well-structured llms.txt file provides a clear, machine-readable summary that benefits any AI system that reads it.
Can llms.txt hurt my SEO or AI visibility?
No. llms.txt is an informational file only. It does not restrict access, block crawlers, or change how your existing content is indexed. It only adds context. There is no downside to having one.
How many pages should I list in llms.txt?
List your 5-15 most important pages. These should be your highest-value content: main product pages, key guides, pricing, documentation, and core landing pages. Do not list every page on your site — that is what your sitemap is for.
