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.
