tenable.com — Global SEODiff Score 68/100

tenable.com
📊

At 80/100, the ACRI for tenable.com indicates strong fundamentals in AI extractability, surpassing the majority of indexed sites. In the government sector, tenable.com outperforms the average (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. A 5.0× bloat ratio is typical for sites in this tech tier — not wasteful, but streamlining could further boost extractability. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
