If Google PageSpeed Insights tells you how a single page is performing, the Core Web Vitals report inside Google Search Console tells you how your entire site is performing at scale. It groups your URLs into Poor, Needs Improvement, and Good categories for both mobile and desktop, drawing on the same Chrome UX Report field data that feeds PageSpeed Insights. The key difference is scope: instead of testing one URL at a time, you get a birds-eye view of every page Google has collected data for.
What makes this report so useful in practice is the URL grouping. Rather than listing every individual page, Search Console groups similar URLs together based on shared patterns and issues. So instead of seeing 400 individual product pages all failing on LCP, you see a single group labelled something like “Similar pages” with 400 URLs affected and the specific metric causing the problem. That makes it much easier to prioritise where to focus your development effort.
I particularly like the fact that fixing issues here directly correlates with ranking improvements, since Google uses these field data thresholds as part of the Page Experience signal. The report also shows you how your numbers have changed over time once you’ve made fixes, giving you a clear before-and-after view. You do need to have your site verified in Search Console to access this, and it only shows data for pages that Google has collected enough real-user data on, so very low-traffic pages won’t appear. For any site with meaningful traffic though, it’s an essential part of your performance workflow.
