Common mistakes

- 2Not disclosing retargeting in the privacy notice — the CNIL enforcement specifically cited transparency failures
- 3Sending product catalogue data including prices without verifying this is necessary for the retargeting use case
Compliance considerations
Sets third-party cookies and processes browsing behaviour for cross-site retargeting. Explicit advertising consent is required under GDPR/ePrivacy. Criteo was subject to a significant CNIL fine (EUR 40 million, June 2023) for consent and transparency failures — ensure robust consent collection and clear disclosure of retargeting in the privacy notice.
