Google PageSpeed and Lighthouse
We run Google's own measurement for mobile and desktop separately. You see both scores, lab metrics such as LCP, CLS, and Speed Index, and the largest resources slowing the page down.
The Speed score is based on real Google PageSpeed measurements — 70% mobile and 30% desktop — because most visitors browse on phones. When Google returns no data, the report says so honestly instead of inventing numbers.

Where Google has real-user field data (CrUX) for your URL, the report shows whether Core Web Vitals pass. Field data availability depends on traffic — smaller sites often only get lab data, and the report labels that clearly.
Slow mobile loading costs visitors before they see your offer. Speed is also a confirmed Google ranking signal, and fast pages get crawled more efficiently.
The report points at the biggest measured problem first — usually oversized images, render-blocking scripts, or slow server response — so you do not waste time on micro-optimizations.
