agentic checks passed 32% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
4sb.cn is live and passes 6 of 30 agentic-readiness checks (32%). It runs on cloudflare over HTTPS.
For AI agents, 4sb.cn's strongest signals are tidy, crawlable markup, fully indexable pages, a visually stable layout, and a lightweight page. Approximately 1049 DOM nodes.
Its main gaps are thin semantic structure, no canonical URL, long, hard-to-quote sentences, and sparse entity coverage. The weakest area is Machine extraction; addressing it first would raise this score the most.
