# Measurement

Enable measurement to track your traffic in a privacy-first manner, optimizing your site's speed tools. To access this feature, you need to enable [Web Analytics](https://developers.cloudflare.com/web-analytics/) on your website. This analytics tool leverages [Real User Measurement](https://developers.cloudflare.com/speed/observatory/run-speed-test/#enable-real-user-monitoring-rum) (RUM) data, providing insights based on actual user interactions to enhance site performance effectively.
