AI bot list, performance grade tables, and glossary of terms.
- AI bots referenceAll 34 AI crawlers BeSeenByAI checks, grouped by category, with user agent strings and what blocking each type means.
- Performance grade referenceGrade thresholds for TTFB, CLS, and INP — what each grade means and what the range implies for AI retrieval.
- Speed and stability metricsHow fast your page and server respond, and how stable the page is while it loads. TTFB is the most critical metric for AI retrieval — slow pages are harder to include reliably.
- GlossaryDefinitions of terms used in BeSeenByAI reports and documentation.
- How to check your server logs for AI crawlersWhen BeSeenByAI reports that AI crawler access could be blocked, your own server or CDN logs are the only place to confirm it. Here is where to look on Cloudflare, nginx, Apache, Vercel, and other hosts.
