hearton.co.jp — Global SEODiff Score 71/100

hearton.co.jp
📊

hearton.co.jp has earned a 90/100 ACRI — a tier-1 result that puts it ahead of 99% of sites in the SEODiff Radar. Its server-rendered architecture ensures AI crawlers receive complete HTML on first request, a key advantage for extractability. The token bloat ratio sits at a lean 3.0×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. Only 1 schema block is present — adding Organization, WebSite, and Breadcrumb schemas would significantly improve structured data coverage. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
