Violations

Tracking cookies were set before the consent decision GCM_002

Cookies: Gdynp, __gfp_64b

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.

Non-compliant tracking after consent was rejected GCM_010

Affected: Seznam Sklik

After a rejection the affected vendors must stop setting identifiers and sending measurement, or run only in a verified cookie-less mode.

Consent state was not restored after page reload GCM_006

Save the consent choice and restore it on subsequent page loads, before tags run.

Non-compliant tracking before consent GCM_009

Affected: Gemius, Seznam Sklik

The affected vendors set an identifier or sent measurement that is not verifiably cookie-less before the visitor chose. Load them only after consent, or configure a documented cookie-less mode that sends no identifiers.

Vendor contacted before consent without identifiers GCM_012

Affected: Google Ads, Google Analytics 4

No identifier was observed, but the visitor's IP address and page context still reached a third party before consent. To be compliant under this check, load the vendor only after consent.

Content Security Policy blocks a vendor's script CSP_001

Affected: Criteo

The site's script-src directive does not allow the listed vendors' script domains, so real visitors' browsers block them. Add the domains to script-src or remove the unused tags.
