1. Core Web Vitals: The Invisible Revenue Factor

Google's Core Web Vitals are not just SEO metrics—they are direct revenue drivers.

• Largest Contentful Paint (LCP < 2.5s): If your primary hero image or headline takes over 2.5 seconds to render, over 50% of mobile executive traffic bounces.
• Interaction to Next Paint (INP < 200ms): If clicking a navigation button or form field causes visual lag, buyers assume your product is equally sluggish.
• Cumulative Layout Shift (CLS < 0.1): Layout shifts cause misclicks on buttons, driving high user frustration.

2. Why Next.js Outperforms Legacy CMS Architecture

Traditional monolithic CMS platforms execute database queries and render HTML on server request, introducing 800ms+ of Time to First Byte (TTFB).

Next.js App Router utilizes Static Site Generation (SSG) and Incremental Static Regeneration (ISR) to deliver pre-rendered HTML straight from global Edge locations (Cloudflare / Vercel), guaranteeing TTFB under 100ms anywhere in the world.
