Short answer: Cloudflare improves website speed through CDN edge caching and enhances security with WAF, DDoS protection, and free SSL. For WordPress, combine Cloudflare with origin caching for maximum performance.
What is Cloudflare?
Cloudflare is a global network that sits between visitors and your server, delivering content from edge locations and blocking threats before they reach your origin.
Performance features
- CDN: Static assets served from 300+ edge locations
- Brotli compression: Smaller file transfers
- HTTP/3: Faster protocol on supported browsers
- APO: Full-page HTML caching for WordPress
Security features
- Free SSL/TLS certificates
- Web Application Firewall (WAF)
- DDoS mitigation
- Bot management
Step-by-step Cloudflare setup
- Step 1: Create Cloudflare account and add your domain
- Step 2: Update nameservers at your registrar
- Step 3: Enable SSL (Full Strict mode)
- Step 4: Configure caching rules and page rules
- Step 5: Install Cloudflare WordPress plugin
- Step 6: Enable Brotli, HTTP/3, and Auto Minify
Cloudflare + WordPress best practices
Purge cache after content updates. Exclude admin and WooCommerce dynamic pages. Pair with server optimization on the origin. See WordPress speed guide.
