The Website Quality Score Explained

How the points are deducted

The total never goes below 0 or above 100. The limits exist so that one noisy check cannot swamp an otherwise sound site. A scan can raise dozens of low-severity items, and they stop counting after 25. The limits for critical and high findings are set so that enough of them can still take a site to zero.

A worked example

Say an assessment reports 1 high, 4 medium and 6 low findings, plus 2 informational ones:

What the bands mean

So the example above, at 74, is Fair, one point short of Good.

Scores by category

A single number says whether to worry, not where to look. Reports therefore also give a score for security, performance, accessibility, mobile, and search and sharing, using the same arithmetic on that category's findings. A category that ran and found nothing shows 100. A category that did not run is not shown at all, because that is different from a perfect result.

Comparing scores

• Compare like with like. A higher level runs more checks and may find more, so an Advanced score can be lower than a Basic score for the same site.
• Expect some movement. Performance varies between runs, and AI-driven tests do not take the same path each time.
• Look at the findings. A run's report shows the change from the previous run, along with what was fixed and what is new.
