What are Core Web Vitals and how do you improve them?
Answer
Core Web Vitals measure real-user page experience:
- **LCP:** loading performance
- **INP:** responsiveness
- **CLS:** visual stability
**Improvements:**
- LCP: optimize images, server response, critical CSS
- INP: reduce long tasks, optimize JS, use web workers
- CLS: reserve space for images/ads, avoid late-loading layout shifts
They matter for UX and can influence SEO via page experience signals.
