SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Performance analysis for SEO audits requires collecting real-user and lab performance data, correlating CWV signals with Lighthouse scores, and producing repeatable reports.

Core Features & Use Cases

Measure CWV metrics (LCP/INP/CLS): obtain CWV signals from real-user data when available, or fall back to Lighthouse measurements
Lighthouse scoring & deterministic artifacts: compute Lighthouse scores and generate repeatable audit artifacts to support SEO decision-making
Shared-cache integration: write results to a shared cache and produce standardized outputs like PERFORMANCE-AUDIT-REPORT.md and SUMMARY.json

Quick Start

Run the performance specialist against a target URL to generate the PERFORMANCE-AUDIT-REPORT.md and SUMMARY.json

FAQPage Schema

How do I generate deterministic Lighthouse and Core Web Vitals reports for SEO audits?▼

To generate deterministic Lighthouse and Core Web Vitals reports, run the audit against a target URL to produce standardized artifacts like PERFORMANCE-AUDIT-REPORT.md and SUMMARY.json. It collects real-user data from PageSpeed Insights or falls back to Lighthouse lab data.

What are Core Web Vitals metrics and how are they measured for SEO performance?▼

Core Web Vitals metrics for SEO performance include LCP, INP, and CLS. They are measured by obtaining real-user signals from PageSpeed Insights when available, or falling back to Lighthouse lab measurements, to support search ranking decisions.

Can I run full-site CWV audits in headless or API environments?▼

Yes, you can run full-site CWV audits in headless or API environments. The process applies deterministic report generation to analyze web performance metrics without a graphical interface, writing final outputs to a shared cache directory.

Do I need PageSpeed Insights data to perform a web performance audit?▼

You do not need PageSpeed Insights data to perform a web performance audit. The system requires PageSpeed Insights data when available, but automatically falls back to Lighthouse lab data when it is not, ensuring the audit completes successfully.

What is the best way to correlate Lighthouse scores with Core Web Vitals signals?▼

The best way to correlate Lighthouse scores with Core Web Vitals signals is to use a performance analysis tool that computes Lighthouse scoring and collects CWV metrics together, generating repeatable audit artifacts for SEO decision-making.

Why does my SEO performance audit fall back to lab data instead of real-user metrics?▼

Your SEO performance audit falls back to lab data when real-user metrics are unavailable. It prioritizes obtaining Core Web Vitals signals from PageSpeed Insights, but seamlessly uses Lighthouse measurements to ensure deterministic report generation continues.
