How fast is your site?

Enter your website address. Google measures it on mobile and desktop, and we show you in plain English what slows it down and what to fix first.

What the report shows

• Four Google scores: performance, accessibility, best practices and SEO.
• Five metrics, such as when the main content appears and how much the layout shifts.
• If Google has enough data: how real visitors experienced the site over the last 28 days.
• Fixes with Google’s estimated gain, most important first.
