agentic checks passed 34% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
kodansha.co.jp is live and passes 5 of 28 agentic-readiness checks (34%). It runs on nginx over HTTPS.
For AI agents, kodansha.co.jp's strongest signals are clean semantic HTML, tidy, crawlable markup, fully indexable pages, and an efficient render path.
Its main gaps are no canonical URL, no structured tables or lists, sparse entity coverage, and few clear definitions. The weakest area is Machine extraction; addressing it first would raise this score the most.
