<objective> Runs a technical SEO audit: fetches and validates robots.txt (`scripts/parse-robots.ts`) and sitemap.xml (`scripts/parse-sitemap.ts`), measures Core Web Vitals via a local Lighthouse wrapper (`scripts/check-cwv.ts` — LCP <2.5s, INP <200ms, CLS <0.1), verifies mobile-first signals, and checks HTTPS/HSTS/redirect chains plus indexability (robots.txt not blocking critical paths, no stray `noindex`, canonical pointing to an indexable URL, no `nofollow` on internal navigation). Does not cover content quality (seo-content), schema (seo-schema), or local-specific signals (seo-local). </objective>

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
