What problem does it solve? Websites often suffer from hidden SEO problems—uncrawlable SPA pages, missing meta tags, broken sitemaps, and weak structured data—that silently suppress search rankings. This Skill provides a systematic audit methodology to detect these issues and produce an actionable, prioritized fix plan. ## Core Features & Use Cases - SPA vs SSR Detection: Determines whether pages are actually visible to Googlebot by curling URLs and inspecting raw HTML, avoiding false assumptions from HTTP 200 responses. - Five-Pillar Audit Methodology: Covers crawlability and indexation, technical foundations (Core Web Vitals, fonts, mobile), on-page optimization, E-E-A-T content quality, and structured data/social meta tags. - SSR Shared Shell Optimization: Identifies high-leverage fixes in shared HTML shell functions (Express/Node SSR) where one change repairs every page at once. - Use Case: A startup's React/Express site isn't ranking. The audit reveals robots.txt returns SPA HTML instead of plain text, the sitemap route is missing, and the shared shell lacks Twitter Card and Organization schema—fixing the shell function resolves meta tags across all pages simultaneously. ## Quick Start Audit my website at https://example.com for SEO issues and give me a prioritized action plan.
