aecom.com — Global SEODiff Score 74/100

aecom.com
📊

aecom.com demonstrates elite AI-Readiness, achieving an ACRI of 86/100 — placing it in the top 99% of all indexed domains. In the infrastructure sector, aecom.com outperforms the average (57), 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. Token bloat registers at 10.0× — 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. The site maintains an open-door policy for AI crawlers — GPTBot, ClaudeBot, and other major agents are all allowed.
