fosonline.gr — Global SEODiff Score 61/100

fosonline.gr
📊

fosonline.gr shows strong AI visibility with an ACRI of 80/100, outperforming 94% of indexed domains. Compared to other infrastructure sites (avg score: 57), fosonline.gr 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. The token bloat ratio sits at a lean 4.4×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. The site includes 3 schema blocks, providing adequate structured data for basic entity recognition. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
