Technical SEO

Workflow

  1. Fetch /robots.txt → scripts/parse-robots.ts
  2. Fetch /sitemap.xml → scripts/parse-sitemap.ts
  3. Run Lighthouse locally → scripts/check-cwv.ts <url>
  4. Verify mobile-first signals (viewport, responsive images)
  5. Check HTTPS, HSTS, redirects chains

Core Web Vitals (2026)

  • LCP: < 2.5s
  • INP: < 200ms (replaced FID March 2024)
  • CLS: < 0.1

Indexability Checks

  • robots.txt doesn't block critical paths
  • <meta name="robots"> not noindex on important pages
  • Canonical points to indexable URL
  • No nofollow on internal navigation
