LLMs.txt Checker & Validator

What Is llms.txt?

It’s like a modern version of robots.txt, but instead of keeping bots out, it invites them in to read exactly what you want them to. It offers better visibility in AI-driven results and improves how your brand is understood by AI tools.

Why Is llms.txt Important for AI SEO?

AI tools are crawling your website already—but they may not see the content the way you want. With llms.txt, you control what they see, ensuring your brand is represented clearly and accurately in AI answers.

Properly structuring your llms.txt file helps LLMs bypass cluttered HTML and focus on your core message.

How to Create an llms.txt File

1. Open a text editor (like VS Code, Notepad, or Sublime Text).
2. Use Markdown format to structure your most important content.
3. Focus on plain text summaries, key pages, and brand messaging.
4. Save the file as llms.txt.
5. Upload it to your website’s root directory (e.g. https://yourdomain.com/llms.txt).

Tip: Use clear language, avoid clutter, and make sure the file is accessible via HTTPS.

Common Mistakes When Using llms.txt

• ❌ Placing the file in the wrong directory (e.g. subfolders instead of root)
• ❌ Using non-Markdown formats like Word or HTML
• ❌ Forgetting HTTPS (some AI crawlers ignore HTTP-only URLs)
• ❌ Including technical jargon instead of plain English summaries

Always validate your file using the tool above to make sure it's live and crawlable.
