Put in a URL and you get its Google PageSpeed Insights score out of 100 on a desktop, and on a simulated phone as well. The desktop score has its own five load timings and its own fixes, with the time each fix saves. It tests a web page, not your internet connection.
What the desktop score means
PageSpeed Insights tests desktop on an emulated desktop with a wired connection. The phone test uses a mid-tier phone on a mobile network. That's why the two scores rarely match, and a page can do well on desktop and badly on the phone.
- 90 or above is good.
- 50 to 89 needs improvement.
- Below 50 is poor.
From Google's PageSpeed Insights documentation, read in October 2026.
Reading the timings and fixes
Under the desktop score are five timings, from First Contentful Paint to Cumulative Layout Shift. Each fix shows the time it saves, so start with the one that saves the most.
Scores move between runs. Google says a score that changes from one run to the next usually reflects changed conditions, not the page itself. Run the test again before you trust a small rise or drop.
Each score comes from a single simulated load of the page, on one device with fixed network conditions. The test doesn't show the real-user data PageSpeed Insights takes from the Chrome User Experience Report, and it doesn't test from different locations.
