# Speed Wins: Why Web Performance Is a Growth Lever

Published: 2024-12-12

## Key takeaways

Web performance is a growth lever, not a developer side project. Slower pages raise bounce rates, reduce conversions and weaken search rankings, since Google uses site speed and Core Web Vitals as ranking signals. The main fixes are image optimization, less JavaScript, server-side or static rendering, CDN caching and mobile-first testing on real devices.

- The Core Web Vitals targets are LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1.
- Images are the easiest win: use WebP or AVIF, responsive sizes, native lazy loading and CDN-based image transformation.
- Code splitting, dynamic imports and tree shaking cut JavaScript, the most expensive resource a browser has to process.
- Server-side rendering, static generation and edge delivery show content sooner than client-rendered pages, especially on slower devices and networks.
- Measure with Lighthouse, WebPageTest and Search Console field data, and prioritize mobile, where nearly all Saudi internet users browse.
