  "account": "Performance is crucial for user experience and revenue. Every 100ms of latency can cost Amazon 1% in sales, while Walmart saw a 2% conversion increase for every 1 second improvement in page load time. Next.js is designed for performance, but can still suffer if optimization isn't understood.\n\nCore Web Vitals measure performance: Largest Contentful Paint (LCP) under 2.5 seconds, Cumulative Layout Shift (CLS) under 0.1, and Interaction to Next Paint (INP) under 200ms. Achieving these targets in the \"Good\" range (75th percentile) is necessary for Google to consider URLs \"Good.\"\n\nNext.js provides free performance wins. Automatic code splitting ensures each page only loads needed JavaScript. Server Components (App Router) default to server-side rendering with no JavaScript overhead. Only add `use client` when necessary. Image optimization with next/image converts to WebP/AVIF, resizes for device, lazy loads, and prevents layout shift. Font optimization with next/font handles self-hosting, automatic preloading, font-display: swap, and variable font slicing. Bundle size optimization should be done using @next/bundle-analyzer to identify larger-than-expected libraries, duplicates, and libraries that should be lazy-loaded.",
  "summary": "Why Performance Matters More Than Ever Google's Core Web Vitals have been a ranking factor since 2021. But beyond rankings, performance is user experience — and user experience is revenue. Amazon found that every 100ms of latency cost 1% in sales. Walmart reported a 2% conversion increase for every 1 second of improvement in page load time. These aren't ancient statistics — they're more relevant…",
