hach.com — Global SEODiff Score 69/100

hach.com
📊

With an ACRI of 86/100, hach.com stands out as one of the highest-performing sites in AI search visibility, outranking 99% of its peers. Compared to other government sites (avg score: 58), hach.com performs above the benchmark, suggesting strong competitive positioning in AI search. Its server-rendered architecture ensures AI crawlers receive complete HTML on first request, a key advantage for extractability. Token bloat registers at 6.0× — acceptable, but reducing inline scripts and redundant markup could yield measurable gains. 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.
