g123.jp — Global SEODiff Score 57/100

g123.jp
📊

g123.jp achieves a 68/100 on the AI-Crawler Reality Index, reflecting above-average readiness for AI-driven discovery. In the infrastructure sector, g123.jp outperforms the average (57), suggesting strong competitive positioning in AI search. The low ghost ratio (5%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. A 48.2× token bloat ratio means crawlers must process significantly more tokens to reach the actual content — a drag on extraction efficiency. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. Robots.txt grants unrestricted access to the key AI user-agents, which is the strongest starting position for AI visibility.
