Quick answer

LCP, INP, CLS — what they mean, why Google ranks you on them, and how to fix each one.

Google ranks fast sites higher. Period. Here's the 2025 fix list.

1. LCP < 2.5s (Largest Contentful Paint)

Compress hero images to WebP, preload them, use a CDN. Most sites pass instantly with this alone.

2. INP < 200ms (Interaction to Next Paint)

Cut JavaScript bundle size. Defer non-critical scripts. Lazy-load chat widgets and analytics.

3. CLS < 0.1 (Cumulative Layout Shift)

Always set width/height on images. Reserve space for ads/embeds. Avoid late-loading fonts (use font-display: swap).

4. Use modern image formats

WebP is 30% smaller than JPG, AVIF is 50% smaller. Convert everything.

5. Enable browser caching + Brotli

Static assets should cache for 1 year. Brotli beats gzip by ~20%.

6. Kill unused CSS/JS

PurgeCSS for Tailwind, tree-shaking for JS. Most sites ship 60% dead code.

7. Test on real 4G, not your fiber

PageSpeed Insights mobile = the score Google actually uses. Fix that first.
