Each category is scored out of 100. 90 or above means your page is performing well in that area. 50–89 means there is room for improvement. Below 50 means there are significant issues that need attention.
How fast your page loads. A slow page frustrates visitors and is penalised by Google in search rankings.
The time until the first piece of content appears on screen. Under 1.8 seconds is good, 1.8–3 seconds needs improvement, over 3 seconds is poor.
The time until the main content of the page has loaded. Under 2.5 seconds is good, 2.5–4 seconds needs improvement, over 4 seconds is poor.
How long the page is unresponsive to clicks while loading. Under 200 milliseconds is good, 200–600 needs improvement, over 600 is poor.
How much the page jumps around while loading. Under 0.1 is good, 0.1–0.25 needs improvement, over 0.25 is poor.
How quickly the visible content loads overall. Under 3.4 seconds is good, 3.4–5.8 seconds needs improvement, over 5.8 seconds is poor.
How long before a visitor can fully use the page. Under 3.8 seconds is good, 3.8–7.3 seconds needs improvement, over 7.3 seconds is poor.
How well your page is set up for search engines. Issues here mean Google may struggle to find, read or rank your page, reducing the number of visitors you get from search.
How usable your page is for people with disabilities. Poor accessibility can also affect SEO and may have legal implications for some businesses.
How readable text is against its background. A minimum ratio of 4.5:1 is required for normal text. Lower ratios mean the text may be difficult to read, particularly for users with visual impairments.
Whether your page follows current web standards and security guidelines. Issues here can affect visitor trust, browser warnings, and how other tools interact with your site.
Whether your page works correctly on mobile devices. Most web traffic is now on mobile, so this directly affects both user experience and search rankings.
