CDN and Caching Strategies for Core Web Vitals

Core Web Vitals and Performance

Speed directly means SEO and conversion. What can be done at the network and browser layer to improve LCP/INP/CLS metrics:

CDN & Cache

• Intelligent caching, stale-while-revalidate
• Image optimization (sizing, lazy-load)
• Use of HTTP/2 and HTTP/3

Render Optimization

• Critical CSS allocation, defer blocking JS
• Server-side rendering + client-side hydrate balance

Result: Users see content faster, and search and sales performance increases.
