Violations

6
Critical
Tracking cookies were set before the consent decision GCM_002

Cookies: Gdyn, Gdynp, __eoi, __gfp_64b, cto_bundle, uid

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.

Critical
Non-compliant tracking after consent was rejected GCM_010

Affected: Gemius, Google Publisher Ads, Adform (adform.com)

After a rejection the listed tools must stop storing visitor IDs and sending measurement, or run only in a verified cookie-less mode.

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: Adform, CPEx, Criteo, Gemius, Google Publisher Ads, Piano, R2B2, Seznam SSP, 33Across, LiveRamp, illumin, Adobe, Adot, AdRoll, Open Web, Simpli.fi, ConnectAd, Conversant, Crimtan, Demandbase, Equativ, Improve Digital, Index Exchange, Inc., LoopMe, Magnite

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.

Warning
Personal data sent to tools without consent GCM_012

Affected: Google Analytics 4

No cookie or visitor ID was stored, but the visitor's IP address and page address — personal data — reached the tool without consent (before the choice or after a rejection). To be Compliant under this check, load the tool only after consent.
