Critical
Tracking cookies were set before the consent decision GCM_002

Cookies: _gcl_au

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.

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
Non-compliant tracking before consent GCM_009

Affected: Gemius, Google Ads, Google Analytics 4, Seznam Sklik, Seznam SSP

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.
