With an ACRI of 86/100, rakuten.co.jp stands out as one of the highest-performing sites in AI search visibility, outranking 99% of its peers. In the healthcare sector, rakuten.co.jp outperforms the average (57), suggesting strong competitive positioning in AI search. A ghost ratio of 15% indicates a mixed rendering strategy where core content loads server-side but interactive sections rely on JavaScript. The 11.2× token bloat ratio falls within the normal range, though there is room to trim navigation, footer, and script overhead. The site includes 2 schema blocks, providing adequate structured data for basic entity recognition. The site maintains an open-door policy for AI crawlers — GPTBot, ClaudeBot, and other major agents are all allowed.
