What the speed test measures

Our speed test analyzes your website's speed on mobile devices using the Google PageSpeed Insights API. The result includes an overall performance score (0-100) and the Core Web Vitals metrics that Google uses as a ranking factor.

The metrics measured are: First Contentful Paint (FCP), the time to display the first content; Largest Contentful Paint (LCP), the time for the main content; Total Blocking Time (TBT), how long the main thread is blocked; Cumulative Layout Shift (CLS), visual stability; and Speed Index, the perceived loading speed.

The report also includes improvement opportunities with estimated time savings in seconds. The most common optimizations involve uncompressed images, unused JavaScript, and render-blocking resources. A fast site improves rankings, reduces bounce rate, and increases conversions.
