Why Caching Matters for Speed
Caching works by storing a fast, static version of your website so visitors don’t load everything from scratch.
When configured properly, caching:
- Reduces server load
- Improves Time to First Byte (TTFB)
- Boosts Core Web Vitals
- Cuts load time dramatically
Image optimization helps too — read that guide here:
