What does the score measure?

The score is a weighted mix of pass, warn, and fail checks: HTTPS, response time, title, description, canonical, Open Graph, headings, an answer-first lead, JSON-LD, llms.txt, sitemap, and robots.txt rules for the major AI crawlers.

Which crawlers are checked?

GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, CCBot, and Applebot-Extended should be allowed if you want citation and training visibility. Bytespider should be blocked.

Why is Bytespider treated differently?

Bytespider is a high-volume scraper. The checker passes when robots.txt disallows it, and warns when the file never mentions it.

Does a high score guarantee rankings?

No. The checker reports whether a page is readable by AI crawlers and whether the usual on-page signals are present. It does not predict rankings or citations.
