nsf.gov SEO & AI Readiness Score: 72/100 (B) — Full Technical Audit

📊

With a solid 79/100 ACRI, nsf.gov is well-positioned for AI search — better than 91% of sites in the Radar. Compared to other government sites (avg score: 57), nsf.gov performs above the benchmark, 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 token bloat ratio sits at a lean 2.8×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. Zero schema blocks puts this site at a disadvantage in knowledge graph and AI-answer pipelines that rely on explicit structured data. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.

💡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.
