AI Agentic Readiness
11 / 28
agentic checks passed 46% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
mixi.co.jp is live and passes 11 of 28 agentic-readiness checks (46%). It runs on Apache over HTTPS.
For AI agents, mixi.co.jp's strongest signals are tidy, crawlable markup, fully indexable pages, a visually stable layout, and a clear canonical URL. Approximately 1399 DOM nodes - consider simplifying.
Its main gaps are text that is hard for agents to extract, no structured tables or lists, long, hard-to-quote sentences, and few clear definitions. The weakest area is Trust & transparency; addressing it first would raise this score the most.
