What the Website Health Check Does
The CoFabrix Website Health Check is a free tool that scores how well any website performs for both human visitors and AI systems in about 30 seconds. It grades a site across six weighted categories: Performance, SEO fundamentals, AI Visibility (how easily AI crawlers and assistants can read and cite the site), Accessibility, Mobile Readiness, and Security and Best Practices. Each scan returns an overall letter grade out of 100, a per-category breakdown, and specific, actionable recommendations.
Analysis Categories
- Performance (20%): Core Web Vitals and page loading speed
- SEO Fundamentals (20%): Search engine optimization basics and metadata
- AI Visibility (20%): How discoverable your site is to AI systems
- Accessibility (15%): Basic accessibility checks (not a full WCAG audit)
- Mobile Readiness (15%): Mobile-specific performance and usability
- Security & Best Practices (10%): HTTPS, security headers, and browser best practices
Your website is analyzed across six categories, each weighted by its impact on your online presence. Every category uses the standard academic grading scale.
