Core Web Vitals 2026 Checklist

Pass LCP < 2.5s, INP < 200ms, CLS < 0.1 on Indian 4G — a battle-tested checklist for WordPress, Shopify, Next.js and custom React apps.

Core Web Vitals is now a ranking factor for both Google Search AND AI Overviews. INP replaced FID in March 2024 — many sites still haven't adapted.

LCP

Largest Contentful Paint < 2.5s

Preload the hero image, use fetchpriority="high", serve AVIF/WebP at correct dimensions, eliminate render-blocking CSS in <head>.

INP

Interaction to Next Paint < 200ms

Break long tasks with scheduler.yield(), defer non-critical JS, lazy-load below-the-fold widgets, and audit third-party tags (chat, analytics, A/B).

CLS

Cumulative Layout Shift < 0.1

Always set width/height on images and embeds. Reserve space for ads and consent banners. Use font-display: optional for late-binding fonts.
