Core Web Vitals scores from your Google Search Console reflect real users on real Indian 4G. Improving them isn't cosmetic — it's revenue.

LCP (Largest Contentful Paint) Preload the hero image. Serve modern formats (AVIF, WebP). Move above-the-fold text out of client components.

CLS (Cumulative Layout Shift) Every image and iframe must have width and height. Reserve space for ads before they load. Never insert content above the fold after first paint.

INP (Interaction to Next Paint) Ship less JavaScript. Break long tasks. Defer analytics and chat widgets until user interaction. Debounce heavy input handlers.

Measure right Field data from Chrome UX Report is the truth. Lab tools (Lighthouse) are a diagnostic, not a scoreboard.
