  • Audits title, description, canonical, Open Graph, Twitter Cards, JSON-LD.
  • Fetches /robots.txt and /sitemap.xml to verify their presence.
  • Inspects heading hierarchy (H1–H6) and detects heading level skips.
  • Checks ARIA landmarks, form labels, skip links, and button/link text.
  • Detects lazy-loaded images, WebP/AVIF usage, and render-blocking CSS.
  • Generates a 4-score report: Performance · SEO · Security · Accessibility.
