Web Quality factor

This factor is part of Web Quality — the weighted 0..100 score that sits above Web Standards. Its weight depends on what kind of site is being measured. Web Standards items take priority; this factor only enters the score once Web Standards passes.

Base weight
0.6 applied to every site type unless overridden below
Why this weight
Cookie scan: actual cookies set on first load (vs declared in policy).

Per-site-type overrides

Site type Weight Δ vs base
E-commerce 0.8 +0.2
News / Publisher 0.9 +0.3
Personal site 0.2 -0.4
Media / Streaming 0.9 +0.3

Site types not listed inherit the base weight.

Same factor, two depths.

What we measure

Many sites set tracking cookies before the visitor accepts the banner. That's a GDPR violation — under the law, no non-essential cookies can be set until the visitor opts in.

How to improve your score

Configure your CMP to block analytics, ad, and marketing cookies until consent is granted. Most CMPs offer this as a one-toggle setting.
