Workflow

Request PageSpeed Insights data from user

Common LCP Issues

Cause	Fix
Slow server response	Improve TTFB, use CDN
Render-blocking resources	Defer non-critical CSS/JS
Slow resource load	Preload LCP image
Client-side rendering	Use SSR/SSG

Common CLS Issues

Cause	Fix
Images without dimensions	Add width/height attributes
Ads/embeds without space	Reserve space with CSS
Web fonts causing FOIT/FOUT	Use font-display: swap
Dynamic content injection	Reserve space, use transforms

Common INP Issues

Cause	Fix
Long JavaScript tasks	Break up tasks, use web workers
Large DOM size	Reduce DOM nodes
Heavy event handlers	Debounce, optimize listeners
Third-party scripts	Defer, lazy load
