LLMs.txt Checker & Validator Tool
Let AI read your content properly
AI tools are here—and they’re reading your website whether you like it or not. The problem? They’re often crawling the noisiest version of your pages. llms.txt fixes that by giving Large Language Models a clean, curated view of what matters.
What is llms.txt?
llms.txt is a proposed plain-text file (usually Markdown) that lives at the root of your site, for example https://example.com/llms.txt. Unlike robots.txt, which tells bots where not to go, llms.txt is an invitation—pointing AI systems to high-quality pages, sitemaps and summaries so they can represent your brand accurately.
Why it helps SEO & AI visibility
- Cleaner signals: Reduce noise from script-heavy pages and surface your most helpful content.
- Stronger brand summaries: Provide a concise “About” paragraph models can quote correctly.
- Faster discovery: Link to sitemaps, documentation, product pages and key posts from one place.
- Safer guardrails: Prefer canonical URLs and avoid outdated or thin pages.
How to use this page
- Generate a starter file with your domain, sitemaps and services.
- Validate the content—check headings, URLs and missing sections.
- Fetch an existing
llms.txtfrom any domain to compare or improve.

Best-practice checklist
- Start with a clear H1:
# Brand — LLMs.txt - Include an “About” sentence that’s factual and concise.
- Add a “Sitemaps” section linking your XML sitemap(s).
- List 5–15 priority URLs: docs, top products/services, pricing, support and blog pillars.
- Use absolute URLs, avoid tracking parameters.
- Keep it lightweight (<150 KB) and update when content changes.
Example: a docs-heavy site (in the style of Zapier)
This is illustrative—replace with your own URLs.

FAQ
Is llms.txt an official standard?
Not yet. It’s a community-driven convention designed to make it easier for AI systems to find and summarise the right content.
How is it different from robots.txt?
robots.txt restricts crawling. llms.txt is opt-in: it highlights the content you want models to read and cite.
Where should I put it?
At your site root (e.g., /llms.txt) so it’s available at https://yourdomain.com/llms.txt.
What should I include?
A one-line brand summary, sitemap links, 5–15 priority URLs, your canonical domain and a contact method.
How often should I update it?
Whenever key pages change—treat it like a living “AI guide” to your site.
