Last checked
17 Jul 2026

ad-c.or.jp is live and passes 6 of 30 agentic-readiness checks (29%). It runs on cloudflare over HTTPS.

For AI agents, ad-c.or.jp's strongest signals are fully indexable pages, a visually stable layout, a lightweight page, and atomic, quotable sentences. 25/28 images declare explicit dimensions.

Its main gaps are thin semantic structure, text that is hard for agents to extract, no canonical URL, and no structured tables or lists. The weakest area is Structured data; addressing it first would raise this score the most.
