A site that loads slowly can frustrate visitors, but one server response measurement is not the same as a full browser performance assessment. Test representative pages on mobile and desktop, repeat measurements, and note network and device conditions. Look for oversized images, blocking scripts, excessive third-party embeds, and layout shifts that interfere with reading or tapping.
Google’s AdSense readiness guidance focuses on user experience and navigation. For web performance metrics, consult Google’s current Core Web Vitals documentation and use appropriate browser tools. Do not describe a simple server-side timing as a Core Web Vitals score.
Use SiteReadyScore for its stated public-site checks, then run browser-based performance measurements for speed. Each tool answers different questions; explain the methods and dates.
