At 67/100, the ACRI for zvab.com indicates strong fundamentals in AI extractability, surpassing the majority of indexed sites. In the infrastructure sector, zvab.com outperforms the average (57), suggesting strong competitive positioning in AI search. While the majority of content is server-rendered, the 15% ghost ratio suggests some content remains hidden from static crawlers. Token bloat registers at 8.8× — acceptable, but reducing inline scripts and redundant markup could yield measurable gains. Only 1 schema block is present — adding Organization, WebSite, and Breadcrumb schemas would significantly improve structured data coverage. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
