In a significant shift announced on December 18, 2024, Google plans to modify its platforms program policies to permit advertisers to use IP addresses for targeting, particularly in Connected TV (CTV) advertising. The changes, set to take effect on February 16, 2025, mark a notable departure from Google's previous stance on IP address protection.
According to Google's official announcement, the policy updates reflect advances in privacy-enhancing technologies (PETs), including on-device processing, trusted execution environments, and secure multi-party computation. These technologies enable brands to manage and activate their data while maintaining user privacy protections.
The timing of this announcement has sparked discussions in the advertising technology sector. According to industry expert Ari Paparo, this move positions Google to compete more effectively in the CTV space, where it currently lags behind competitors. "Their business severely lags the competition (who all use IP), so this is an opening for them," Paparo stated on social media.
The Google blog post is interesting. They are giving themselves a hall pass for using IP addresses in CTV, as long as it is obscured using PETs. Their business severely lags the competition (who all use IP), so this is an opening for them.https://t.co/ojAfg0s3da https://t.co/cI8dwf6Kc6

The policy modification addresses two major shifts in the advertising ecosystem. First, the advancement of privacy-enhancing technologies has created new methods for brands to handle data securely. Second, the rise of new advertising platforms, particularly Connected TV, has changed how users interact with content and advertisements.
In the CTV sector, IP addresses serve as crucial identifiers for reaching relevant audiences and measuring campaign effectiveness. The fragmentation of the streaming environment has made this particularly challenging for advertisers. Google's policy update aims to address these challenges while maintaining privacy standards.
The technical implementation involves several components. Google plans to utilize confidential computing within its advertising products, allowing businesses to use first-party data without re-identifying users. This approach differs from traditional IP address targeting by incorporating privacy-preserving protections.
Statistical data underscores the significance of this change. According to figures cited in the announcement documents, Connected TV represents one of the fastest-growing advertising channels. This growth has created pressure for more sophisticated targeting capabilities while maintaining user privacy.
The policy updates also clarify prohibited activities to protect users. These include restrictions on advertisements that simulate operating system warnings with deceptive intent. Additionally, the policy maintains requirements for transparency, mandating that advertisers and publishers clearly communicate their data collection and usage practices to users.
Industry observers note the broader implications for the advertising ecosystem. The implementation of privacy-enhancing technologies could set new standards for data usage across the web. Google has indicated plans to partner with the broader advertising industry to make these technologies more accessible.
The timing of these changes aligns with ongoing discussions about privacy in digital advertising. The Department of Justice has previously expressed concerns about search term data and monopoly practices. This context adds another layer of complexity to Google's policy shift.
Google's announcement emphasizes that despite technological changes, core privacy principles remain unchanged. Users maintain choice over personalized advertisements, and transparency requirements for advertisers and publishers continue. The company positions these updates as an adaptation to technological advancements while maintaining privacy standards.
The implementation timeline gives advertisers and technology providers approximately two months to prepare for these changes. The new policies will affect various advertising surfaces, including Connected TVs and gaming consoles, reflecting the expanding scope of digital advertising beyond traditional web browsers.
This policy change represents a significant development in the ongoing evolution of digital advertising technology, balancing the industry's need for effective targeting capabilities with growing demands for user privacy protection. The success of this approach will likely depend on the practical implementation of privacy-enhancing technologies and their adoption across the advertising ecosystem.
