SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Page speed is critical to user experience and SEO; this skill helps teams quickly identify performance bottlenecks and actionable optimizations using PageSpeed Insights data.

Core Features & Use Cases

  • PSI-driven auditing: analyzes lab (Lighthouse) and field (CrUX) data to surface bottlenecks and improvement opportunities.
  • Core Web Vitals optimization: provides guidance to improve FCP, LCP, CLS, INP, and TTFB to meet "Good" thresholds.
  • Evidence-based recommendations: outputs concrete, testable steps and validation checks aligned with official PSI guidelines.

Quick Start

Run the PageSpeed Insights Auditor on a page URL to generate actionable performance improvements.

FAQPage Schema
How do I audit my website's PageSpeed Insights score and identify bottlenecks?▼

To audit website performance and identify bottlenecks, you analyze both lab data from Lighthouse and field data from CrUX. This process surfaces specific improvement opportunities to help boost page speeds to 90+.

What is the best way to improve Core Web Vitals like LCP, CLS, and INP?▼

Improving Core Web Vitals requires analyzing FCP, LCP, CLS, INP, and TTFB metrics against official PSI thresholds. You implement evidence-based recommendations and concrete optimizations to meet the 'Good' performance tier.

How do I optimize web page performance when lab and field data show different results?▼

Optimizing web page performance with conflicting data involves analyzing the differences between Lighthouse lab tests and real-user CrUX field data. This identifies consistent bottlenecks and provides structured steps for asset optimization.

Can I use PageSpeed Insights guidelines to fix SEO page speed issues?▼

Yes, PageSpeed Insights guidelines effectively address SEO page speed issues by providing data-driven insights. Web developers and SEOs can implement concrete, testable validation checks aligned with official performance thresholds.

Why does my web page speed score drop below 90 even after image optimization?▼

A web page speed score below 90 can persist due to unoptimized Core Web Vitals like TTFB or INP. Auditing lab versus field data identifies remaining bottlenecks across pages and assets beyond images.

Do I need Lighthouse installed locally to audit field data from CrUX?▼

No, you do not need Lighthouse installed locally to audit field data, because CrUX provides real-user metrics independently. However, combining both lab and field data offers a complete view of web performance.
