Erros Comuns

  • 1 Deploying the remarketing tag without consent - sets third-party cookies and enables cross-site tracking before opt-in
  • 2 Enabling Enhanced Conversions without updating the privacy notice - hashed PII transmission is additional processing
  • 3 Not configuring Consent Mode v2, preventing cookieless conversion modelling when consent is denied
  • 4 Using the same conversion action across domains without understanding that cross-domain attribution shares user identifiers
  • 5 Setting inappropriate conversion windows and attribution models, inflating conversion counts

Considerações de Conformidade

Sets first-party and third-party cookies (_gcl_au, _gcl_aw, IDE) and transmits conversion and remarketing data to Google servers.

Consent: Explicit consent typically required under GDPR/ePrivacy before firing on EU/UK sites. Remarketing constitutes cross-site tracking - categorise under advertising consent in your CMP.

Enhanced Conversions: Sends hashed first-party data (email, phone) to Google. Requires disclosure in your privacy notice and may need additional consent depending on legal basis.

International transfers: Covered by EU-US Data Privacy Framework - verify your Google entity's DPF self-certification status.

Consent Mode v2: Allows cookieless conversion modelling when consent is denied, but pings may still constitute personal data processing in some jurisdictions.

High Amazon Ads

Amazon Ads (formerly Amazon Advertising) provides a JavaScript pixel and conversion tracking tag that measures user actions on advertiser websites and sends data back to Amazon's demand-side platform (DSP) and sponsored ads ecosystem. The Amazon ad tag enables conversion attribution, audience building, and retargeting across Amazon's owned properties and its extensive third-party publisher network. Amazon's advertising business has grown rapidly to become the third-largest digital advertising platform globally behind Google and Meta. The Amazon Ads pixel is increasingly found on e-commerce, retail, and consumer goods websites, and its integration with Amazon's vast consumer data ecosystem raises significant governance considerations for regulated organisations.
