Meta Will Mine AI Conversations for Ad Targeting Starting December 16

Meta announced in October it will begin using user interactions with its generative AI features to personalize content and ad recommendations across Facebook and Instagram on December 16. The shift extends the company's behavioral-signal infrastructure into conversational data—what users ask and explore via AI—marking the first time Meta is harvesting this signal class for ad-targeting. The company framed it as a product improvement. Engineers recognize it as a qualitatively richer form of intent data than passive behavioral signals, capturing declared interest rather than inferred preference.
