orbi.kr — Global SEODiff Score 72/100

orbi.kr
📊

Registering an exceptional 87/100 on the AI-Crawler Reality Index, orbi.kr sits in the highest tier of AI extractability among indexed domains. Compared to other infrastructure sites (avg score: 57), orbi.kr performs above the benchmark, 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 tight 3.9× token bloat ratio reflects disciplined markup: minimal noise between the crawler and the content it needs. 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.
