Question 1

What is llms.txt?

Accepted Answer

llms.txt is a plain-text (Markdown) file placed at the root of your domain (yoursite.com/llms.txt) that helps large language models understand your website. It contains a curated list of your most important pages with descriptions, organized into sections like Products, Documentation, and Company.

Question 2

Why do I need an llms.txt file?

Accepted Answer

AI assistants like ChatGPT, Claude, and Perplexity use llms.txt to quickly understand what your business does and find your key pages. Without it, AI crawlers must guess which content matters most, often leading to incomplete or inaccurate information about your site in AI responses.

Question 3

How does the checker work?

Accepted Answer

Enter any domain and we'll fetch its llms.txt file, analyze the content, and report back on whether it's present, valid, and properly formatted. We'll flag issues like missing descriptions, lack of sections, or too few linked pages.

Question 4

How does the generator work?

Accepted Answer

Enter your domain and our tool scans your homepage to detect common page patterns (About, Products, Pricing, Docs, etc.). It then generates a properly formatted llms.txt file with these sections that you can download and upload to your site.

Question 5

What format should llms.txt follow?

Accepted Answer

llms.txt uses simple Markdown: start with a # H1 heading for your company name, include a > blockquote with a one-line description, then use ## H2 headings for sections (Products, Docs, Company) with bullet lists of links in the format [Label](URL): Description.

Question 6

Where do I put the llms.txt file?

Accepted Answer

Upload llms.txt to your website's root directory so it's accessible at yoursite.com/llms.txt. It must be named exactly 'llms.txt' (all lowercase, no file extension) and served as plain text.

Question 7

Is llms.txt officially supported by AI companies?

Accepted Answer

llms.txt is an emerging standard that several AI companies are beginning to support. While not universal yet, early adopters are seeing better representation in AI-generated responses. It's similar to how sitemap.xml became standard for search engines.

Question 8

How does this relate to the SEO Snapshot tool?

Accepted Answer

The AI Visibility + SEO Snapshot tool checks whether your llms.txt exists as part of its comprehensive AI readiness audit. If it's missing, the snapshot will recommend using this generator. Together, they help optimize your entire AI visibility strategy.

Question 9

Is this tool free?

Accepted Answer

Yes, you can check any domain and generate llms.txt files for free. Creating a free account unlocks higher daily limits.

Question 10

What if my site has a complex structure?

Accepted Answer

The generator creates a starting template based on common patterns. For complex sites, download the generated file as a starting point, then customize it by adding more sections, adjusting descriptions, and prioritizing your most important content.
