PageSpeed Insights

Google's public performance testing tool combining lab and real-user data.

PageSpeed Insights returns a Lighthouse audit (lab data) alongside Chrome User Experience Report (CrUX) field data showing real-world Core Web Vitals from actual visitors. Field data drives Google's ranking signals, while lab data identifies optimisation opportunities. Wix sites typically score higher on PSI than they did historically due to ongoing platform performance improvements.
