About this skill

What it does

This skill analyzes website performance using Google Lighthouse, providing detailed reports on metrics like accessibility, best practices, SEO, and performance scores.

The results are presented in a structured format suitable for further processing or reporting.

  • A/B Testing Analysis: Compare the performance of different versions of a webpage after A/B testing changes.
  • SEO Monitoring: Track SEO scores over time to ensure ongoing optimization efforts are effective.
  • Accessibility Audits: Quickly assess a website's accessibility compliance and identify potential issues for users with disabilities.

Key capabilities
