Visiblio / PageSpeed
Is this page fast enough, and what should be fixed first?
Visiblio asks Google to test a page on a phone and a computer, then explains the result in plain words: what each score means, which Core Web Vitals pass, what to fix first, and who has to do it (a developer, the content team or the hosting team).
Any public page works, yours or a competitor's. Google runs the test, which takes 20 to 60 seconds.
How to read these numbers
- Real visitors is data Google collects from Chrome users over 28 days. It is what Google uses for ranking. Small pages may not have it.
- Lab test is one test run now on a simulated phone or computer. It is good for finding causes, but a single run can vary by a few points.
- The three Core Web Vitals are the largest content time (LCP), the page reaction time (INP) and the page jumping (CLS).
- The explanations and the "who fixes it" labels are written by Visiblio. The measurements come from Google PageSpeed Insights. Nothing you test is stored on a server; the last address is remembered in this browser only.
