ana.gov.br — Global SEODiff Score 67/100

ana.gov.br
📊

With a solid 84/100 ACRI, ana.gov.br is well-positioned for AI search — better than 98% of sites in the Radar. In the infrastructure sector, ana.gov.br outperforms the average (57), suggesting strong competitive positioning in AI search. The low ghost ratio (5%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. A tight 2.4× token bloat ratio reflects disciplined markup: minimal noise between the crawler and the content it needs. Structured data coverage is solid at 2 blocks, covering core entities — expanding to include FAQ or Breadcrumb schemas could strengthen the profile further. Robots.txt grants unrestricted access to the key AI user-agents, which is the strongest starting position for AI visibility.
