The Technical Trust section evaluates whether your site looks production-ready from a technical perspective. This covers performance, accessibility, security, and platform hygiene.
What gets checked
- Lighthouse Performance
- Lab-based performance scores including First Contentful Paint, Largest Contentful Paint, Total Blocking Time, and Cumulative Layout Shift. These are lab measurements, not field data.
- Lighthouse Accessibility
- Automated accessibility checks covering color contrast, alt text, ARIA labels, heading structure, and keyboard navigation.
- Security Headers
- Checks for Strict-Transport-Security (HSTS), Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy.
- Caching
- Whether cache-control headers, ETags, and Vary headers are configured properly for static and dynamic resources.
- Mobile Readiness
- A mobile-first spotlight that evaluates responsive design, touch targets, viewport configuration, and mobile-specific rendering issues.
- Runtime Stability
- Checks for JavaScript errors, console warnings, failed network requests, and mixed content issues captured during the rendered scan.
- Platform Hygiene
- Technology stack detection, server headers, and whether common platform-specific issues are present.
Interpreting technical scores
Technical scores combine Lighthouse lab data with the security, caching, and runtime evidence. A site can score well on Lighthouse but poorly overall if it has missing security headers or runtime errors. Focus on runtime failures and accessibility blockers before optimizing for marginal Lighthouse gains.
