Meta will use your activity on other websites to personalize your feeds

Meta is planning to use data shared by other businesses to personalize user feeds and AI responses on Facebook and Instagram. According to a blog post, Meta already utilizes off-platform activity, such as games played and purchases made on other websites, to serve ads and will now expand this personalization to content. For instance, if a user recently bought a tent online, they may see camping-related videos in their Reels feed. Meta states that it is not collecting any new data with this update, but rather using existing information provided by businesses.
