Introduction

Google Consent Mode (GCM) bridges the gap between data privacy regulations and digital advertising efficiency. It modifies the functionality of Google tags based on users' consent preferences, ensuring compliance without compromising valuable insights for campaign optimization and ad monetization.

Key Features

  • Respect for User Consent: GCM adjusts the operation of Google tags to align with users' consent decisions regarding ads and analytics cookies.
  • Insight Collection: It enables advertisers to gather crucial data on campaign conversions and other metrics while adhering to consent choices.
  • Ad and Analytics Cookie Management: GCM dynamically alters tag behavior based on the consent status for advertising and analytics purposes.

Consent Status Impact

  • Consent Granted: When users consent to cookies, Google measurement tools operate typically, allowing full tracking and data collection capabilities.
  • Consent Withheld: Without consent, Google tags will not utilize ad cookies. Instead, they resort to alternative measurement methodologies that aggregate data at a higher level, ensuring privacy compliance.
