asthmaandlung.org.uk — Global SEODiff Score 66/100

asthmaandlung.org.uk
📊

The AI-Readiness profile for asthmaandlung.org.uk is strong: an ACRI of 66/100 places it ahead of 57% of domains in the index. The low ghost ratio (0%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. Token bloat registers at 5.3× — 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. Partial bot access means the domain is visible to some AI systems but not accessible to others — GPTBot remain blocked.

💡Organization schema missing. AI models cannot identify your brand entity. Without it, your brand won't appear in Knowledge Panels or be associated with your content.
💡Product / Service schema missing. AI models don't know this is a SaaS product. Add Product or SoftwareApplication schema so AI understands what you offer and can surface pricing/features.
💡BreadcrumbList schema missing. AI cannot understand your site hierarchy or how pages relate to each other.
💡FAQ schema missing. Adding FAQPage schema lets AI models directly extract Q&A pairs for Featured Snippets and chatbot answers.
💡WebSite schema missing. Add WebSite + SearchAction so Google can generate a Sitelinks Search Box for your brand in AI results.
