Key Findings
1. Why llms.txt Matters
AI search engines are becoming primary sources of information. llms.txt gives them a concise summary of your site, helping them decide when to cite you. It's like a sitemap for AI, but much simpler.
2. What to Include in llms.txt
Your llms.txt should include your site name, a brief description, key sections, and a list of important URLs or content types. Keep it under 10 lines if possible. NakedURL checks if the file exists and tells you if it's missing.
- Site name and tagline
- Brief description of your content
- List of main sections (e.g., Blog, Products, About)
- A few example URLs if relevant
3. How to Create llms.txt
Simply create a text file called `llms.txt` and place it in your website root. Use plain text, avoid markdown, and keep it straightforward. NakedURL will detect it immediately and give you credit for it.

Without llms.txt, AI models may overlook your content
- No llms.txt – AI doesn't know your site structure

Best practices
Tips on what to include in your llms.txt.
I put llms.txt in my root, but NakedURL doesn't detect it. Why?
Check the file name and location. It must be exactly `llms.txt` (lowercase) in your public root directory. Also, ensure it's accessible via `https://yourdomain.com/llms.txt`. NakedURL will detect it if it's publicly accessible.
