Use this tool to test how quickly a webpage loads and identify performance issues that may affect visitors. Page speed should be evaluated through several measurements rather than a single full-load time, since a page may appear usable before every background resource has finished loading.
Google’s Core Web Vitals focus on loading performance, responsiveness, and visual stability through Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. These measurements are used as part of Google’s broader page-experience systems, but strong performance scores alone do not guarantee higher rankings. :contentReference[oaicite:0]{index=0}
Improving speed is still important because slow or unstable pages can frustrate visitors, delay interactions, and reduce conversions. Use the results to identify oversized images, render-blocking resources, slow server responses, unnecessary scripts, and other elements that may be affecting the user experience.
