Questions about this tool
What is a good score?
90 or above is good. But Core Web Vitals (LCP, INP, CLS) matter more than the score.
Why is my phone score low?
Phone tests use a slower network and CPU. Big images and many scripts hurt most.
Does speed affect Google ranking?
Page experience, including Core Web Vitals, is one of many ranking signals. Speed also helps sales.
Why does it show an example?
Testing other websites needs our server, which goes live after launch.
Will testing slow my site?
No. It loads your page once, like one visitor.
