Why Performance Matters
Website performance directly impacts user experience, search engine rankings, and business metrics. A fast website can increase user engagement, reduce bounce rates, and improve conversion rates.
Core Web Vitals
Google's Core Web Vitals are key metrics for measuring user experience:
- Largest Contentful Paint (LCP): Measures loading performance (target: < 2.5s)
- First Input Delay (FID): Measures interactivity (target: < 100ms)
- Cumulative Layout Shift (CLS): Measures visual stability (target: < 0.1)
Image Optimization
Images often account for the largest portion of page weight:
- Choose the Right Format: Use WebP for photos, SVG for icons, PNG for graphics with transparency
- Compress Images: Use tools like TinyPNG or ImageOptim
- Responsive Images: Serve different sizes for different screen sizes
- Lazy Loading: Load images only when they're about to enter the viewport
Conclusion
Performance optimization is an ongoing process that requires attention to detail and continuous monitoring. By implementing these techniques, you can significantly improve your website's performance and user experience.
