A Content-Delivery Network (CDN) is a network of servers distributed globally to deliver content, such as images and videos, faster to users. CDNs reduce latency by caching content closer to the user’s location, improving website load times and user experience.

CDNs are essential for advertisers who rely on fast-loading ads to engage users. By using CDNs, advertisers and publishers can enhance ad performance, reduce loading times, and create a smoother browsing experience.
