Transparency and targeting of political advertising

Transparency and Targeting of Political Advertising refers to Regulation (EU) 2024/900, a European Union law adopted in March 2024 that introduces harmonised rules for transparency and targeting in political advertising across all EU member states.^[1]

Transparency and Targeting of Political Advertising
Long title Regulation (EU) 2024/900 on the transparency and targeting of political advertising
Enacted	March 2024
Commenced	Autumn 2025 (most provisions)
Status: In force

The regulation complements the Digital Services Act, General Data Protection Regulation (GDPR), and the EU Code of Practice on Disinformation. It responds to increasing concerns about the influence of microtargeting in elections, especially by third-country actors.^[1]

Scope and Definitions

The regulation broadly defines political advertising to include the preparation, placement, promotion, delivery, or dissemination of messages that are:

• By, for, or on behalf of political actors,
• Or designed to influence the outcome of elections, referenda, or legislative/regulatory processes.

Covered actors include political parties, campaign organisations, elected officials, and issue-based groups. Even civil society campaigns are affected if they relate to political or legislative outcomes.^[1]

Key Provisions

The regulation introduces the following core obligations:

Transparency and labelling

• Political ads must include a clear label and link to a transparency notice.
• The notice must disclose the sponsor, purpose, amount paid, targeting criteria used, and associated electoral or policy event.^[1]

Targeting Restrictions

• Targeting based on special categories of personal data (e.g. political opinions, ethnicity, health) is prohibited.
• Ads cannot be targeted to individuals under voting age or within one year of eligibility.^[1]

Third-Country Restrictions

• In the three months before elections or referenda, providers can only offer political advertising services to EU-based entities not controlled by foreign interests.^[1]

Record-Keeping and Compliance

• Advertisers and intermediaries must retain key documentation (e.g. sponsor identity, payment info, service scope) for seven years.
• Content creators, platforms, and ad tech providers share liability and must set up contractual arrangements to clarify responsibilities.^[1]

Repository for Political Ads

A central EU repository for online political advertising will include metadata standards, authentication protocols, APIs for third-party access, and allow stakeholders (e.g. journalists, researchers, civil society) to request machine-readable data from providers under Article 17.

Implementation timeline

• March 2024: Regulation adopted by the Council and Parliament.
• 2025: Draft implementation guidance published.
• Autumn 2025: Most obligations become applicable.^[2]

Reactions

Withdrawals from advertising platforms

Google announced its exit from the EU political ad market in late 2024, highlighting the regulation’s broad scope and lack of reliable electoral data.^[3]

Meta Platforms announced that it will suspend all political and issue-based ads on its platforms in the EU from October 2025, citing "legal uncertainty" and "operational challenges".^[4]

Civil Society Concerns

Critics argue the regulation risks conflating civil society with political parties, placing excessive burdens on NGOs, grassroots campaigns, and issue-driven communication. Groups have warned this may chill speech on topics like abortion or domestic violence when connected to legislative processes.^[3]

Observers have flagged issues including, overly broad definitions of “political advertising”, lack of technical guidance ahead of enforcement, disproportionate impacts on small and medium enterprises, risk of democratic distortion due to reliance on dominant platforms like Meta.^[3]
