Consent Management USP is the most widely adopted consent management platform, used by 317,574 publisher websites according to Red Volcano's data.
A CMP is a tool that helps publishers collect, manage, and store user consent for data processing and advertising. CMPs are essential for compliance with GDPR, CCPA, and other privacy regulations. They typically display cookie consent banners and manage user preferences.
CMP adoption is crucial for programmatic advertising because consent signals determine whether personalized ads can be served. Publishers without a CMP may lose access to premium demand sources that require verified consent, particularly in European markets.
Red Volcano identifies CMPs through JavaScript tag analysis, TCF (Transparency & Consent Framework) API detection, and known CMP vendor signatures. Our weekly crawl detects which CMP each publisher uses.
