mpc-web.jp has earned a 88/100 ACRI — a tier-1 result that puts it ahead of 99% of sites in the SEODiff Radar. Compared to other infrastructure sites (avg score: 57), mpc-web.jp performs above the benchmark, suggesting strong competitive positioning in AI search. Content is delivered server-side, meaning bots and AI agents can parse the full page without executing JavaScript. A 10.3× bloat ratio is typical for sites in this tech tier — not wasteful, but streamlining could further boost extractability. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
