GDPR Requirements for Advertising

Lawful Basis for Ad Targeting

Under GDPR, you need a valid legal basis:

Basis	When Applicable	For Advertising

Consent	User explicitly agrees	Required for most targeting
Legitimate Interest	Balance test satisfied	Limited applicability
Contract	Necessary for service	Rarely applicable to ads

Consent Requirements

Valid consent must be:

• Freely given — No bundled consent
• Specific — Purpose clearly stated
• Informed — User understands implications
• Unambiguous — Clear affirmative action
• Withdrawable — Easy to revoke

Data Processing Requirements

Data Protection Impact Assessment — Required for high-risk processing

Record of Processing Activities — Document all data processing

Data Subject Rights — Access, deletion, portability

Cross-Border Transfers — Ensure adequate safeguards

Practical Compliance Strategies

Strategy 1: The Highest Common Denominator

> "Adopt compliance frameworks that meet the strictest requirements across all applicable states rather than managing state-specific variations."

Implementation:

• Apply California-level protections everywhere
• Single privacy policy covering all jurisdictions
• Unified consent management system
• Consistent data handling practices

Strategy 2: First-Party Data Infrastructure

Reduce third-party dependencies:

Email/SMS capture — Own the relationship

Account creation — Logged-in experience

Server-side tracking — Your data, your control

Enhanced conversions — Privacy-safe measurement

Customer data platform — Unified first-party view

Strategy 3: Contextual Advertising

Privacy-compliant targeting based on content:

Contextual Signal	Targeting Approach

Page content	Relevant product placement
Article topic	Topic-based targeting
Weather	Location-based without tracking
Time of day	Temporal targeting
Device type	Non-personal device targeting

Strategy 4: Privacy-Preserving Measurement

Measure without personal tracking:

• Aggregated reporting — No individual-level data
• Conversion modeling — Platform-based estimation
• Media mix modeling — Statistical analysis
• Incrementality testing — Holdout-based measurement
• Data clean rooms — Privacy-safe matching

Technical Implementation

Consent Management Platform (CMP)

Essential for compliance:

Features needed:

• Geo-detection for regional rules
• GPC signal detection
• Consent storage and retrieval
• Integration with ad platforms
• Audit trail and reporting

Recommended CMPs:

• OneTrust
• Cookiebot
• TrustArc
• Usercentrics

Server-Side Tracking

Shift from client-side cookies:

Google Enhanced Conversions — Hashed first-party data

Meta Conversions API — Server-side event delivery

First-party cookies — Longer lifespan, your domain

Customer data integration — CRM-based targeting

Privacy-Safe Advertising Features

Platform	Feature	Function

Meta	Conversions API	Server-side tracking
Google	Consent Mode	Privacy-aware measurement
Google	Enhanced Conversions	Hashed data matching
Meta	Aggregated Event Measurement	iOS privacy compliance
Google	GA4 Consent Settings	Regional privacy settings

Advertising in the AI Era

EU AI Act Implications

Responsible AI Advertising

Best practices for AI in ads:

Transparency — Disclose AI use when required

Human oversight — Review AI decisions

Bias monitoring — Check for discriminatory targeting

Explainability — Understand how AI makes decisions

Documentation — Record AI system decisions

The Future of Privacy in Advertising

Trends to Watch

Cookie deprecation — Third-party cookies ending (finally)
