What the checker looks at

The checker runs 56 checks in 7 categories. 6 of the checks are tracked: they are reported but not scored. The score runs from 0 to 100 and maps to a grade from A to F.

  • Bot Accessibility — robots.txt and whether it lets AI agents and AI search fetchers in, sitemap, status codes, response time and Markdown content negotiation.
  • Structured Data — schema.org markup (present, typed, complete and valid), Open Graph tags, heading hierarchy and semantic HTML.
  • Content Quality — Answer-first writing, token efficiency, content length, lists and tables, FAQ content, citation readiness, freshness signals and author attribution.
  • Agent Discovery — llms.txt and whether its links resolve, an A2A agent card, and markdown alternates of your pages.
  • Agent Protocols — MCP endpoints, discoverable APIs, structured forms, action schemas, UCP, and whether the OpenAI, Perplexity and Google agent user agents can reach your pages.
  • Technical Foundations — HTTPS, security headers, canonical URLs, a mobile viewport, UTF-8 charset, and content that renders without JavaScript.
  • Auth & Access — Public API, OpenAPI spec, OAuth discovery with PKCE, scoped permissions and an RFC 9727 API catalog.

Extra checks can be added for some site types, such as ecommerce and local business. Training crawlers like GPTBot and ClaudeBot are reported but not scored. A check that depends on an API you do not offer is marked not applicable instead of failing.

Website AI readiness vs. an AI readiness assessment

An enterprise AI readiness assessment rates an organization for adopting AI: its data, infrastructure, skills, governance and strategy. This checker rates one public website instead. It tests whether AI agents, crawlers and assistants can reach, read, understand and act on that site. It is automated, free, takes a URL and needs no sign-up. It does not assess your company's internal AI maturity.

Frequently asked questions

What is website AI readiness?

It is how well AI agents, crawlers and assistants can reach, read, understand and act on your public website. It covers access rules, structured data, content, discovery files, agent protocols and authentication.

How is the score calculated?

Each category is scored from its checks. The overall score is a weighted sum of the category scores, from 0 to 100. Grades: A is 75 or more, B 60 or more, C 45 or more, D 30 or more, and F below 30. See the methodology for every check and weight.

Does blocking GPTBot or other AI training crawlers lower my score?

No. Training crawlers like GPTBot and ClaudeBot are reported but not scored. Blocking user-initiated agents such as ChatGPT-User, or AI search fetchers such as OAI-SearchBot and PerplexityBot, does lower the score.

Is the audit free? Do I need an account?

The audit is free. You enter a URL and get a report. You do not need to sign up.

What if the checker cannot reach my site?

The checker names the reason instead of scoring an error page. The reason can be an anti-bot block, an unreachable site, a login requirement, rate limiting or a timeout. No score is computed from an anti-bot challenge page.

Does llms.txt matter?

It helps coding agents and AI tools that fetch it, and the checker looks for it. Google says its AI features need no special AI files, so do not expect llms.txt to change your Google visibility. Use the llms.txt validator to check the file.
