Qu’est-ce que Lighthouse Optimization Score
Google Lighthouse is a browser-based tool that audits websites for performance, accessibility, SEO, and best practices. It generates a report with scores (0-100) and actionable recommendations. The report highlights bottlenecks: "Images too large, use WebP", "Third-party scripts block rendering", "Low color contrast on buttons". Lighthouse is built into Chrome DevTools, available as CLI tool, and integrated into CI/CD pipelines. It's the de facto standard for web quality assessment (2024+).
