holscience.com — Global SEODiff Score 65/100

holscience.com
📊

holscience.com shows strong AI visibility with an ACRI of 79/100, outperforming 91% of indexed domains. Compared to other education sites (avg score: 58), holscience.com performs above the benchmark, suggesting strong competitive positioning in AI search. Content is delivered server-side, meaning bots and AI agents can parse the full page without executing JavaScript. A 23.4× token bloat ratio means crawlers must process significantly more tokens to reach the actual content — a drag on extraction efficiency. Only 1 schema block is present — adding Organization, WebSite, and Breadcrumb schemas would significantly improve structured data coverage. The site maintains an open-door policy for AI crawlers — GPTBot, ClaudeBot, and other major agents are all allowed.
