Grades any public page on how readable it is to the crawlers behind ChatGPT, Claude, Perplexity, Gemini and Copilot — not to Google's blue links.
Whether GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and eleven others are actually allowed through — parsed from your live robots.txt against this exact path, plus a real request sent with a bot user-agent to catch WAF filtering.
AI crawlers largely do not run JavaScript. We count the words present in the raw server response, detect client-only framework shells, and check whether the page is chunked into sections small enough to retrieve.
JSON-LD schema, canonical identity, sitemaps, llms.txt, Open Graph — the unambiguous statements about what the page is, who wrote it, and when it last changed.
