How to Optimize Website Performance π
A fast, well-optimized website improves user experience, SEO rankings, and conversion rates. Here’s how to maximize performance:
1οΈβ£ Optimize Page Load Speed β‘
β
Use a CDN (Content Delivery Network)
- Distributes content across global servers to reduce load time.
- πΉ Example: Cloudflare, Akamai, AWS CloudFront.
β
Enable Gzip Compression
- Reduces file sizes and improves load speeds.
β
Minimize HTTP Requests
- Combine CSS/JS files, use inline SVGs, and limit external scripts.

Implement Lazy Loading
- Loads images & videos only when visible.
πΉ Tool: Google PageSpeed Insights
2οΈβ£ Optimize Images & Media πΌοΈ
