Frequently asked questions
Why is my speed score different every time?
Lab tests vary with network and server load from run to run. Real-user data is much steadier, so trust it when it's available.
Is page speed a ranking factor?
Yes, as part of Google's page experience signals, but a light one – relevant, helpful content matters more. Speed matters most for keeping visitors.
