Understanding AI Readiness

llms.txt Content (30 pts)

Your AI identity file that tells language models about your business.

  • File exists: Must be accessible at /llms.txt (10 points)
  • H1 heading: Clear business name using # syntax (10 points)
  • Blockquote: Mission statement using > syntax (10 points)
  • Bonus: At least 100 characters of content (+5 points)

Schema.org Markup (30 pts)

  • JSON-LD script: Present on homepage (15 points)
  • Valid @type: Organization or LocalBusiness (15 points)
  • Bonus: Business name included (+10 points)
  • Must match llms.txt data for maximum AI trust

robots.txt Discovery (20 pts)

Helps AI crawlers find your llms.txt file automatically.

  • File exists: robots.txt accessible at root
  • References llms.txt: Uses "Allow:" or "Link:" directive (20 points)
  • Best practice: Add both Allow and Link directives

sitemap.xml Entry (20 pts)

Ensures AI crawlers prioritize your llms.txt file.

  • File exists: sitemap.xml accessible at root
  • Includes llms.txt: Listed in <url> entries (20 points)
  • Set priority to 0.8 for optimal AI crawler attention

Why AI Readiness Matters in 2026

🤖

AI Search is Growing

ChatGPT, Claude, Gemini, and Perplexity now handle 40%+ of search queries. Your business needs to be discoverable.

First-Mover Advantage

Most businesses (95%+) don't have llms.txt yet. Being AI-ready now = huge competitive edge.

📈

More Visibility = More Customers

Businesses mentioned by AI get 3-5x more inquiries. AI readiness directly impacts revenue.

Best Practices for AI Readiness

Do This

  • Create llms.txt first - it's the foundation of AI discoverability
  • Add Schema.org markup on your homepage for context
  • Include llms.txt in robots.txt and sitemap.xml for discoverability
  • Keep llms.txt updated monthly (services, contact info, offerings)
  • Use our copy-paste fixes - they're tested and production-ready
  • Run this audit monthly to catch any broken configurations

Avoid This

  • Don't create llms.txt without Schema.org - they should match
  • Don't use generic templates - customize for your business
  • Don't block /llms.txt in robots.txt (defeats the purpose!)
  • Don't ignore the fixes - a low score means lost AI traffic
  • Don't copy competitors' llms.txt - AI detects duplicate content
  • Don't wait - competitors are implementing this now

Frequently Asked Questions

What score should I aim for?

Aim for 71% or higher to be considered "AI-Ready". A score of 100%+ (with bonuses) means you're fully optimized for AI discovery and puts you in the top 1% of websites.

How is this different from the Validator?

The Validator checks llms.txt content quality only. This Checker performs a comprehensive infrastructure audit covering all 4 critical files: llms.txt, Schema.org markup, robots.txt discovery, and sitemap.xml listing.

Are the fixes really copy-paste ready?

Yes! Every fix includes exact code customized for your domain. Just copy the code, paste it into the specified file, and upload to your server. No coding knowledge required - we've tested every template.

Is the audit really free?

Yes! The complete audit (score, breakdown, file discovery, copy-paste fixes) is 100% free for everyone - no signup required. This free version gives you everything you need to get AI-ready.

How often should I run this audit?

Run it after any changes to llms.txt, Schema.org markup, or site structure. We recommend monthly audits as a best practice to catch broken configurations. Set a calendar reminder for the first Monday of each month.

What if I score 0%?

Don't worry! This is actually common (95%+ of websites have no AI infrastructure). Use our llms.txt Generator to create your foundation file in 2 minutes, then implement the other fixes. You can go from 0% to 100% in under an hour.

Can I check competitors' websites?

Yes! Enter any public website URL to see their AI readiness score. This is great for competitive analysis - see who's optimized and who's missing the AI opportunity. Learn from leaders in your industry.

Do I need all 4 files to rank in AI search?

llms.txt is the minimum requirement for AI discovery. However, Schema.org markup helps AI understand context, while robots.txt and sitemap.xml ensure AI crawlers can find your llms.txt file. All 4 together maximize your AI visibility.

Will this work for my industry?

Yes! AI readiness applies to every industry - e-commerce, SaaS, local businesses, agencies, consultants, nonprofits, and more. Any business that wants to be found by ChatGPT, Claude, Gemini, or Perplexity needs these 4 files.
