Learn what a CDN is and how content delivery networks improve website speed, user experience, and Core Web Vitals that impact SEO link performance
A CDN (Content Delivery Network) is a system of geographically distributed servers that work together to deliver web content quickly to users based on their location. By serving content from the nearest server, CDNs significantly reduce page load times. For SEO and link building, CDNs matter because page speed is a confirmed ranking factor, and faster sites provide better user experiences that support higher engagement metrics. When your site loads quickly, the pages receiving backlinks are more likely to retain visitors, strengthening the behavioral signals that complement link equity. CDNs also improve site reliability, ensuring that backlinked pages are consistently accessible to both users and search engine crawlers.
