What are Core Web Vitals?

Google Core Web Vitals are three metrics that measure user experience: LCP, INP, and CLS.

Why clean HTML wins

Faster LCP

No JavaScript to parse before rendering. Content appears immediately.

Better INP

No framework overhead processing events. Native browser handling is faster.

Zero CLS

Static layouts do not shift. Predictable rendering.

Optimization tips

Images

Use modern formats (WebP, AVIF). Set explicit dimensions. Implement lazy loading.

Fonts

Use font-display: swap. Preload critical fonts. Limit font variations.

CSS

Inline critical CSS. Defer non-critical styles. Minimize unused CSS.

Clean HTML is not just about simplicity. It is about performance.
