agentic checks passed 39% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
yahoo.co.jp is live and passes 8 of 30 agentic-readiness checks (39%). It is served over HTTPS.
For AI agents, yahoo.co.jp's strongest signals are clean semantic HTML, tidy, crawlable markup, fully indexable pages, and a visually stable layout.
Its main gaps are few clear definitions, no Schema.org structured data, shallow schema coverage, and no speakable schema for voice agents. The weakest area is Machine extraction; addressing it first would raise this score the most.
