castbox.fm — Global SEODiff Score 60/100

castbox.fm
📊

At 83/100, the ACRI for castbox.fm indicates strong fundamentals in AI extractability, surpassing the majority of indexed sites. Within the finance vertical, this places castbox.fm above the industry average of 58 —, suggesting strong competitive positioning in AI search. The low ghost ratio (0%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. Heavy markup overhead (50.0× bloat) forces AI systems to wade through excess code before finding useful information. The site includes 2 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.
