Optimizing Core Web Vitals with clean HTML
How production-ready HTML helps you achieve better performance scores.
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.
