Optimize Core Web Vitals by implementing RUM and Lighthouse CI to track LCP, INP, and CLS. Address slow load times through bundle analysis, code splitting, and image optimization to improve page speed and user engagement metrics.

Reduce JavaScript payload size using webpack-bundle-analyzer to inspect assets and Next.js dynamic imports for code splitting. Tree-shaking unused modules further decreases bundle sizes and improves overall web performance.

Implement caching strategies by configuring effective HTTP and server-side caching using Redis. Caching reduces server load and repeat request latency, significantly improving website load speed and user experience across the full stack.

Yes, use k6 for load testing to simulate user traffic and identify performance bottlenecks. Simulating traffic helps detect slow load times and large asset size issues before they impact real users under high concurrency.

Yes, image optimization serves modern formats like WebP and AVIF with responsive sizing. Using the Next.js Image component and Sharp, it processes and delivers optimized images, reducing large asset sizes that cause poor user experience.

High bounce rates often occur due to slow website loading times and poor user experience. Fix them by measuring Core Web Vitals, identifying large unoptimized images and JavaScript bundles, and implementing caching strategies to improve page speed.
