What This Skill Does

Runs comprehensive technical SEO audits covering Core Web Vitals (LCP, CLS, INP, TTFB), crawlability, indexability, mobile-friendliness, HTTPS security, URL structure, redirect chains, robots.txt, XML sitemaps, hreflang, canonical tags, and structured data. Produces a health score from 0 to 100 with issues sorted by severity and a prioritized fix roadmap.

Covers crawlability, performance, security, structured data, and international SEO in one audit workflow instead of requiring separate tools for each area.

When to use it

  • Diagnosing a sudden drop in Google search rankings
  • Pre-launch technical check before a new site goes live
  • Auditing robots.txt and sitemaps before a domain migration
  • Finding why Googlebot cannot crawl or index specific pages
  • Improving Core Web Vitals scores ahead of a product release
