Web-performance-optimization helps developers measure and improve website performance across loading speed, Core Web Vitals metrics, bundle size, caching, and runtime efficiency. It guides users through a systematic five-step process: establishing baseline metrics with Lighthouse audits, identifying bottlenecks like unoptimized images and render-blocking resources, prioritizing high-impact optimizations, implementing improvements such as code splitting and asset optimization, and verifying results through before/after comparisons. This skill solves the problem of slow-loading websites and applications that negatively impact user experience and SEO rankings.
