Regulatory Landscape
The European Data Protection Board (EDPB) has issued updated guidelines reinforcing:
- Broader scope of the “cookie rule” – URLs, pixels, and local processing are all subject to consent.
- No “cookie walls” – Access cannot be conditioned on accepting cookies.
- Affirmative action required – Implied consent (e.g., scrolling) is invalid.
- Right to withdraw – Users must retain the ability to revoke consent anytime.
Implementation Best Practices
Granular Consent
- Allow users to accept specific categories (Functional, Analytics, Marketing) while rejecting others.
- Provide clear language explaining what each cookie category tracks.
Persistent Withdrawal
- Offer a clear, always-accessible way to revoke consent at any time.
- Ensure the “Reject all” button remains functional after initial consent.
Technical Implementation
- Integrate a compliant cookie banner before any tag fires.
- Enable Google Consent Mode v2 in GTM with default settings denied.
- Set tag behavior to respect consent signals (
ad_storage,analytics_storage).
