The role of consent in advertising
Consent provides the foundation for sustainable, transparent, and trust-based marketing. With privacy expectations on the rise worldwide and regulations growing more complex, advertisers face a clear challenge: deliver meaningful campaigns while respecting the choices consumers make about their data. Consent provides the foundation for sustainable, transparent, and trust-based marketing.
Without a clear and standardized way to communicate consent across platforms, data privacy controls become fragmented. This creates regulatory risks and weakens customer confidence. Advertisers that manage consent effectively build stronger relationships and protect the integrity of their campaigns.
How Amazon Consent Signal supports consent-driven advertising
Amazon Consent Signal (ACS) is a consent-sharing format developed by Amazon to help advertisers and third parties share user consent choices when uploading or sharing customer data with Amazon Ads .
When customer data flows into Amazon Ads, the Amazon Consent Signal ensures every step of data handling, whether analysis, measurement, or activation, aligns with the consent preferences granted by the user.
For advertisers, this framework makes it possible to:
- Indicate whether personal data can be processed for advertising measurement
- Respect user opt-outs consistently across Amazon Ads products and services
- Support privacy-compliant audience planning and campaign optimization
This framework ensures that advertising performance relies on data that reflects genuine user choices, strengthening both compliance and trust.
Bringing consent data from OneTrust into Amazon workflows
OneTrust’s Consent Management Platform (CMP) captures user consent in real time across web, mobile, and CTV experiences. With configurable categories and geolocation rules, advertisers can transparently collect granular permissions aligned with GDPR, CCPA, and other privacy laws.
Through an integration with Amazon Consent Signal, OneTrust helps advertisers:
- Capture and Store Consent: Collect user choices at the point of interaction and record them with full audit trails
- Map Consent Choices to Amazon’s Framework: Align OneTrust categories with Amazon’s required consent fields for precise data handling
- Transmit Consent Signal: Ensure that the consent status from OneTrust is formatted and available for use in Amazon’s privacy-aware Ads products and services
This direct mapping creates a single source of consent truth, providing advertisers confidence that their Amazon Ads ecosystem is compliant.
For companies, it also simplifies operations by centralizing consent data instead of spreading it across disconnected tools. For users, this means the preferences they select remain consistent whether their data supports audience analysis, campaign activation, or measurement.
