SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Poor Core Web Vitals (LCP, INP, CLS) are a confirmed Google search ranking factor, but most site owners struggle to diagnose real-user performance failures and implement effective, targeted fixes that actually improve search visibility.

Core Features & Use Cases

  • Real-User Focused Diagnosis: Prioritizes CrUX field data and Search Console reports over lab-only Lighthouse scores, so you fix the issues that actually impact your search performance.
  • Metric-Specific Fix Guidance: Provides clear, actionable steps for each Core Web Vital, including LCP image optimization, INP JavaScript reduction, and CLS layout shift prevention.
  • Use Case: If your e-commerce product pages are ranking lower than competitors, use this skill to identify failing Core Web Vitals, apply the recommended fixes, and confirm ranking improvements after deployment.

Quick Start

Use the seo-performance skill to diagnose the Core Web Vitals issues hurting your website's Google search rankings and implement targeted fixes for each failing metric.

FAQPage Schema
Why do my PageSpeed Insights scores differ from real-user CrUX data?▼

PageSpeed Insights provides lab-only Lighthouse scores, while CrUX data measures actual visitor performance. This skill prioritizes real-user CrUX field data to ensure your optimizations target the issues genuinely impacting search visibility.

What is the best way to resolve high INP on e-commerce product pages?▼

Resolve high INP on e-commerce product pages by targeting JavaScript reduction and execution optimization, applying actionable metric-specific fixes that align with Google's official Core Web Vitals thresholds for real-user interaction latency.

Can I use this approach to diagnose SaaS landing page performance issues?▼

Yes, you can diagnose SaaS landing page performance issues using this approach, which applies to public-facing websites and targets real-user measured performance gaps identified via Search Console reports or CrUX field data.

When should I not rely on blanket performance improvements for SEO?▼

Avoid blanket performance improvements when specific Core Web Vitals metrics are failing, as non-impactful general optimizations waste effort. Targeted guidance aligned with Google's LCP, INP, and CLS thresholds is necessary for actual ranking gains.
