LinkedIn Expands AI Data Use and Microsoft Ad Targeting

LinkedIn is implementing significant changes to its terms of service, effective November 3, 2025, that will expand how the platform uses member data for artificial intelligence training and advertising purposes. The updates will allow greater data sharing with parent company Microsoft and enhanced AI processing capabilities.

Enhanced Microsoft Ad Personalization

The most notable change involves LinkedIn sharing additional member data with Microsoft to deliver more personalized advertisements across the Microsoft ecosystem. This includes LinkedIn profile information, feed activity data, and ad engagement metrics. Users outside the European Union will see Microsoft ads tailored based on their LinkedIn behavior and professional interests.

Members can opt out of this data sharing through Microsoft’s privacy settings, though they will continue seeing Microsoft advertisements—just without the LinkedIn-based personalization. The company emphasizes that only data already permitted for advertising purposes will be shared, maintaining existing privacy boundaries.

AI Training Data Expansion

LinkedIn is also broadening its use of member data for training generative AI models in regions including Canada, Hong Kong, Switzerland, and the UK. The AI training will utilize profile details and public content to improve features that help recruiters connect with candidates and assist members in creating professional content.

The “Data for Generative AI Improvement” setting defaults to enabled, requiring users to manually opt out if they prefer their information not be used for AI model training. Private messages remain excluded from this data collection.

These changes reflect LinkedIn’s strategy to leverage its professional network data for enhanced user experiences while balancing privacy concerns. Members who continue using the platform after November 3 will automatically accept these updated terms, making immediate review and potential opt-out decisions crucial for privacy-conscious users.
