Use when the question is how well ChatGPT, Claude, Perplexity and Gemini can find, read and cite a web page: 0-100 score, letter grade, pass/fail checks (answer-bot access in robots.txt, server-rendered text, title and meta, JSON-LD, canonical, llms.txt, sitemap) and a prioritized fix list with points per fix. Blocking training crawlers does not lower the score. Errors: 400 bad_input, 502 site unreachable. Failed calls are not charged.
