Marketers Must Prioritize GPC Compliance to Avoid Legal Risks
Global Privacy Control (GPC) is emerging as a legal compliance priority for U.S. marketers as state privacy laws proliferate and California increases enforcement under the CCPA. GPC, created by a coalition including Brave, DuckDuckGo and major newspapers, lets users signal opt-out of sale/sharing of personal data. California regulators have treated GPC as a valid CCPA signal and have levied multi‑million dollar fines (for example, the Sephora case). Websites can honor GPC via modern Consent Management Platforms (CMPs) that detect the signal and block sale/sharing through tag management systems, or via custom implementations (a published JSON file approach from The Washington Post and Wesleyan University). Marketing impact to date appears limited because GPC signal prevalence is low, but legal risk is rising, so marketers, legal and IT teams should prioritize implementation and testing.
Rising enforcement (multi‑million dollar fines) and California precedent make GPC compliance an immediate legal requirement with material implications for tracking, consent tooling (CMPs), and marketers’ data collection strategies.

- Most Consent Management Platform (CMP) vendors now offer GPC detection features that can block data collection related to sales/sharing via tag management systems.
- A custom GPC implementation using a JSON file was developed/published by The Washington Post and Wesleyan University as an alternative to CMP-based approaches.
- Current measured marketing impact of GPC is limited due to low observable signal prevalence, but legal enforcement risk is increasing.
