CDN setup can improve more than loading speed
A properly configured CDN can reduce latency, improve delivery quality, lower origin load, and help protect the website through caching layers and traffic filtering. For many WordPress sites, Cloudflare is also one of the fastest ways to improve SSL handling and edge delivery at the same time.
But CDN setup only helps when it is configured correctly. Incorrect DNS, SSL, redirect, or cache behavior can create mixed-content issues, stale content, login problems, or new technical confusion.
