PageSpeed & Core Web Vitals Checker
See the speed numbers Google actually ranks on, not just a lab score.
Most speed tools lead with the big Lighthouse score out of 100. That score is a simulation run on a throttled connection in a data centre, and it is not the number Google uses. This one leads with field data instead: what Chrome recorded from your real visitors over the last 28 days, at the 75th percentile, for LCP, INP, and CLS — the three Core Web Vitals that are an actual ranking signal. Each metric comes with the spread across visits, because a page can look acceptable on average while a quarter of the people opening it are having a bad time. The lab run is still shown underneath, labelled for what it is: the place to look for causes. Below that sits the ordered list of what to fix, largest saving first. Pages too quiet for Google to report on individually fall back to site-level numbers, and the tool says so rather than showing an empty box.
