The best CMP choice
for Amazon advertisers

Avoid the risk of data mishandling

If you share personal or user-level data from UK or EEA users with Amazon Ads (or with third-party data providers feeding Amazon Ads), you must convey those users’ privacy choices through one of the accepted signals, either the IAB TCF or Amazon Consent Signal. Without those signals, Amazon may block or reject ad delivery, targeting or measurement of that data.

Advertising Performance

Maximize your advertising efforts while staying compliant

Missing or non-compliant consent signals can block campaigns, impressions, or attribution. With Didomi and ACS, you protect measurement accuracy and audience reach while aligning with EU privacy standards and Amazon’s policies (Amazon Ads is a registered IAB TCF vendor).

If you advertise in the UK or EEA and process personal data for Amazon Ads, ACS helps you meet GDPR and ePrivacy requirements, without compromising marketing performance.

Consent-aware Amazon Signal

Configure tags and uploads to match user consent

ACS communicates a user’s privacy choices to Amazon Ads in a standardized, privacy-safe way across tags and data uploads:
‍
• User data consent: whether personal data may be used for advertising (granted or denied).
• Ad storage consent: whether Amazon may read or write identifiers or cookies in the browser (granted/denied).

In practice, these appear as fields like amzn_user_data and amzn_ad_storage in consent payloads. Didomi automatically populates and forwards the right values based on user choices. Amazon Marketing Cloud (AMC) accepts consent signals (TCF, GPP, and ACS), ensuring privacy-safe measurement and audience workflows when configured correctly.
