AI Site Health Checker is a free tool that scores how ready your website is for the new generation of AI crawlers, answer engines, and autonomous agents. Paste any URL and get an instant, plain-English report across three pillars — Readable, Discoverable, and Navigable — plus the exact files you need to fix every gap it finds.
Why AI-readiness matters
Search is changing. People increasingly get answers from ChatGPT, Claude, Perplexity, and Google's AI overviews instead of clicking through ten blue links. Autonomous agents now browse, compare, and transact on behalf of their users. If your site renders its content only in the browser, hides its links behind JavaScript click handlers, or never declares a policy for AI bots, these systems simply skip you. Being agent-ready means your content is present in the raw HTML, your structure is machine-readable, and your capabilities are discoverable — so AI systems can find, understand, and recommend you.
What we check
The audit runs nineteen checks grouped into three pillars:
- Readable (crawlers & AI bots) — is your primary content in the initial HTML, or trapped in an empty JavaScript shell? We look for real text, a single clear <h1>, semantic landmarks like <main> and <nav>, genuine <a href> links, image alt text, a canonical tag, and a working robots.txt and sitemap.xml.
- Discoverable (Answer Engine Optimization) — can answer engines understand what you are? We check for Schema.org JSON-LD structured data, entity markup such as Organization or FAQ, a meta description, Open Graph tags, and substantive, self-contained content.
- Navigable (A2A) — can autonomous agents orient themselves? We look for an llms.txt content map, an A2A Agent Card at /.well-known/agent-card.json, explicit AI-bot rules in robots.txt, and semantic navigation structure.
How it works
Enter a URL and press Run Audit. We fetch your page and its root resources exactly the way a crawler would, score each check, and assign an overall grade from A to F. Every failed check comes with a specific, actionable hint. When you are ready to fix them, the generator produces ready-to-ship files — robots.txt, sitemap.xml, llms.txt, an Agent Card, and JSON-LD structured data — tailored to your site.
Connect an AI agent (MCP)
Prefer to work through an AI assistant? AI Site Health Checker is also a remote MCP server. Point any MCP-capable agent at our endpoint and it can audit sites, read the full playbook, and generate the same compliance files directly inside your workflow — no copy-and-paste required.
Frequently asked questions
- Is the audit free? Yes. Scoring any URL is completely free and requires no account.
- What does "agent-ready" mean? It means AI crawlers can read your content, answer engines can understand and cite it, and autonomous agents can navigate and act on it.
- Why did my single-page app score low? Client-rendered apps often ship an empty HTML shell, so crawlers see no content. Pre-rendering or server-rendering your key pages fixes this — which is exactly what this very page does.
- Do I need to change my whole site? No. Most sites reach a top grade by adding a handful of small files and making their main content visible in the initial HTML.
