Content Delivery Network (CDN)
A Content Delivery Network (CDN) is a globally distributed network of proxy servers designed to deliver web content to users based on their geographic location. When a user in London requests a webpage hosted in New York, a CDN serves the heavy assets (images, CSS, JavaScript) from a local server in London, drastically reducing latency. Because page speed and Core Web Vitals are confirmed ranking factors, utilizing a high-performance CDN (like Cloudflare or Fastly) is non-negotiable for any website operating at scale. A CDN is the fastest way to artificially decrease server response times and secure algorithmic speed advantages.
Content Delivery Network (CDN) Simplified
A CDN is a network of servers spread all over the world that hold copies of your website’s images and files. When someone visits your site, the CDN sends the files from the server physically closest to them, making your website load lightning-fast no matter where the user lives.
