What is PageSpeed Insights?
PageSpeed Insights combines lab and field data (CrUX) to evaluate load performance and Core Web Vitals.
Lab data helps debugging; field data shows real user experience. Read both and prioritize – do not chase only the lab score. Complementary to GSC CWV reports for URL groups.
