CDN analytics is essential for measuring content delivery performance and user engagement, enabling businesses to make data-driven improvements. Key metrics include latency, cache hit ratio, bandwidth usage, and error rates, while user engagement is evaluated through page load times, bounce rates, and session durations. Geographic performance analysis helps identify regional inefficiencies, and security analytics detects threats like DDoS attacks. Best practices suggest real-time monitoring, setting benchmarks, A/B testing, and integration with broader analytics tools. Akamai mPulse, Cloudflare, Fastly, and Google Cloud are among the popular CDN analytics platforms. Effective use of these tools enhances speed, reliability, and global user experience.
