Page Speed Optimization

It is the process of making pages load and respond quickly by improving server delivery, reducing asset weight, and streamlining the critical rendering path so users see content fast.

Focus on Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Aim for LCP under 2.5 seconds, low INP for quick input response, and CLS below 0.1 for visual stability.

Use modern formats like WebP or AVIF, resize to real display sizes, compress aggressively, serve responsive images with srcset and sizes, and lazy load below the fold media.

Inline only critical CSS, defer or async nonessential scripts, split bundles by route, and remove unused code. Keep third party scripts to a minimum and load them after main content.

Preload key font files, enable font display swap to avoid invisible text, subset character sets, and prefer variable fonts to reduce total file requests.

Fast hosting, object caching, optimized databases, HTTP 2 or HTTP 3, and a global CDN reduce latency and speed up delivery for both static and dynamic content.

Use PageSpeed Insights, Lighthouse, and field data from Chrome UX Report or your Real User Monitoring tool. Track changes alongside conversions, bounce rate, and crawl stats.

Compress and convert images, enable CDN caching, defer noncritical scripts, preload key fonts, and fix layout shifts by setting explicit width and height on media.
