Google Lighthouse is a tool that audits web pages for performance (Core Web Vitals), accessibility, SEO, and best practices. Developers use it to identify bottlenecks and fix them. High scores correlate with user retention and SEO ranking. Mastery takes 2-4 weeks. Understanding Lighthouse is standard for all frontend developers (2024+). Demand is universal.

Apa iku 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+).

Performance Optimization

❓ FAQ

What are Core Web Vitals?
Three metrics Google cares about: LCP (largest contentful paint, <2.5s), FID (first input delay, <100ms), CLS (cumulative layout shift, <0.1). These measure user experience. High scores = happy users = higher ranking.
Can I improve my Lighthouse score without code changes?
Partially. Caching, CDN, image optimization help. But real improvements need code changes (lazy loading, reducing JavaScript, optimizing CSS). Performance = engineering problem.
What's the difference between Lighthouse and WebPageTest?
Lighthouse: Google's automated tool, quick results, integrated in Chrome DevTools. WebPageTest: detailed waterfall analysis, multiple locations, more advanced. Use both: Lighthouse for fast feedback, WebPageTest for deep dives.
How often should I run Lighthouse?
Before every deploy (CI/CD). Every week if no deployments. Monitor trends. Score dropping? Investigate. Score improving? Celebrate.
Can AI help with Lighthouse scores?
Yes. AI can suggest optimizations (lazy load images, minify JS). Some tools like Vercel's Speed Insights use ML to forecast performance. But implementation is manual.
