This Skill addresses slow web pages by identifying bottlenecks in loading, runtime performance, and resource usage, then applying targeted optimizations.
Run a Lighthouse audit on your site to identify bottlenecks. Implement recommended optimizations such as preconnects, preloads, compression, caching, and code-splitting. Re-audit to verify improvements.

Web performance bottlenecks can be identified through Lighthouse audits, which analyze loading times, runtime performance, and resource usage. Run an audit on your site to pinpoint issues like slow server response, unoptimized images, or render-blocking resources, then apply targeted fixes such as compression, caching, and code-splitting to improve Core Web Vitals metrics.
Core Web Vitals—Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP)—measure loading performance, visual stability, and responsiveness. Search engines and browsers prioritize pages with strong Core Web Vitals, making optimization essential for both user experience and search ranking.
Image and font optimization reduces page weight and load time through format conversion (e.g., WebP), responsive sizing, compression, and lazy loading. Font subsetting and preloading critical fonts further improve performance. Lighthouse audits recommend specific optimizations for your site's assets.
Yes, Lighthouse audits can be automated and integrated into CI workflows to continuously track performance metrics and catch regressions. Running audits on every build provides before/after metrics and alerts you to changes that degrade Core Web Vitals or load times.
Caching strategies—browser caching, service worker caching, and server-side caching—control how long assets are stored and reused. Browser caching suits static assets with long lifespans, service workers enable offline functionality, and server caching reduces database load. Lighthouse recommendations guide selection for your use case.
Yes, this optimization targets both desktop and mobile environments. Mobile sites often face stricter performance constraints due to network and CPU limits, so audits and improvements prioritize mobile-first optimization while maintaining desktop gains.
