nlr.nl — Global SEODiff Score 55/100

nlr.nl
📊

At 78/100, the ACRI for nlr.nl indicates strong fundamentals in AI extractability, surpassing the majority of indexed sites. In the developer sector, nlr.nl outperforms the average (57), 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. The bloated 27.8× token ratio highlights an urgent need to clean up non-content markup, scripts, and navigation clutter. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. Some AI crawlers are permitted while others are blocked — a mixed robots.txt policy that limits visibility in certain AI ecosystems.

  • Allow GPTBot in robots.txt so AI crawlers can access your pages (see Crawl Access).
  • Reduce token bloat (navigation/footer/code) so agents reach your main content faster (see Token Bloat).
  • Create an llms.txt file so AI crawlers can discover your content structure without heavy crawling. Generate llms.txt →
