Meta European Ad Revenue Slows Following Less Personalized Ads Rollout
Meta reports decelerating ad sales in Europe as users shift to less personalized advertising options mandated by regulators.

Key points
- European advertising revenue grew 18 percent year-on-year through September, lagging US and Canada growth of 33 percent.
- Meta introduced Less Personalized Ads in early 2024 after EU regulators fined the company €200 million for Digital Markets Act breaches.
- The new ad model uses 90 percent less data, leading to lower advertiser returns and fewer transactions in the region.
Meta disclosed on Wednesday that advertising revenue in Europe continued to decelerate during the quarter ending in September. The region’s growth of 18 percent year-on-year underperformed its global figures. This slowdown contrasts with the 33 percent growth recorded in the United States and Canada during the same period. The divergence highlights potential regional impacts on monetisation strategies.
Root cause
The performance gap may stem from the introduction of the Less Personalized Ads model. EU regulators ruled that Meta breached its Digital Markets Act obligations by failing to provide an equivalent service using less personal data. Consequently, the European Commission fined the firm €200 million. Meta launched the LPA option at the beginning of this year to comply with these rulings.
Attack path
N/A. This event involves regulatory compliance and business model adjustments rather than a technical vulnerability or security breach. The "path" here is regulatory enforcement leading to product changes that alter user data availability for advertisers.
Affected versions
- European Union users on Facebook and Instagram platforms.
- Advertisers targeting audiences within the European Economic Area.
- Meta’s advertising revenue streams originating from European markets.
Mitigation
- Monitor regional compliance requirements for digital advertising practices.
- Adjust budget expectations for European campaigns based on reduced targeting precision.
- Review privacy settings and user consent mechanisms for alignment with local laws.
- Track competitor responses to similar regulatory mandates in other jurisdictions.
What it means for organisations
Organisations should assess how reduced data granularity affects campaign performance and return on investment in regulated markets. Marketing teams must evaluate whether current attribution models remain valid with limited user data. Legal and compliance departments need to verify that advertising practices align with evolving Digital Markets Act interpretations. Senior leadership should prepare for potential revenue volatility in regions with strict privacy mandates. Internal communication should clarify expectations for regional performance metrics.
What to do and how to stay safe: Meta
- Audit current advertising strategies to identify reliance on high-precision user data.
- Develop contingency plans for markets where personalised advertising restrictions are implemented.
- Monitor regulatory announcements regarding data usage and consumer consent requirements.
- Engage with legal counsel to ensure compliance with new digital service obligations.
