fr12.nl — Global SEODiff Score 71/100

fr12.nl
📊

fr12.nl shows strong AI visibility with an ACRI of 77/100, outperforming 86% of indexed domains. Within the infrastructure vertical, this places fr12.nl above the industry average of 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. The token bloat ratio sits at a lean 4.1×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. 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.
