Violations

6
Critical
Tracking cookies were set before the consent decision GCM_002

Cookies: Gdyn, Gdynp, __gfp_64b, _ga, _ga_JNRHHJJ0B1

Do not write analytics or advertising cookies until the visitor has made a consent choice. Load GTM/GA4 tags behind a denied consent default and let the CMP's update unblock them.

Critical
Consent Mode does not update in place after the consent choice GCM_008

Affected: broken

Call gtag('consent', 'update') immediately after the visitor's choice, with the correct values for both accept and reject. Do not rely on a page reload: it creates duplicate pageviews and breaks session attribution.

Warning
Cookie wall: no option to reject tracking CMP_002

Affected: Criteo, Gemius, Google Ads, Google Analytics 4, Google Publisher Ads, Seznam SSP, Google Universal Analytics, onthe.io

Refusing consent must be as easy as giving it. Add a clearly visible Reject all button to the consent banner; pay-or-consent models without a free reject option may not constitute valid consent.

Warning
Consent Mode default is missing GCM_001

Call gtag('consent', 'default') with denied values before GTM or GA4 loads, so the initial consent state is explicit.

Warning
Consent state was not updated after the banner choice GCM_003

Make both the accept and the reject button update the consent state through the GTM Consent API or gtag('consent', 'update').

Warning
Non-compliant tracking before consent GCM_009

Affected: Gemius, Google Analytics 4, Google Publisher Ads, Seznam SSP, Google Universal Analytics, onthe.io

The listed tools stored a visitor ID or sent measurement before the visitor chose, without a verified cookie-less mode. Load them only after consent, or configure a documented cookie-less mode that sends no IDs.
