From CNET: Facebook said Wednesday that Apple's upcoming privacy update could make it tougher for the social network to target some iPhone users with ads on other mobile apps.
Facebook offers a service to businesses called the Audience Network, which lets businesses use the social network's targeting to run ads on thousands of mobile apps. Facebook collects a trove of data from its users, allowing advertisers to target potential customers based on age, location and other criteria.
Apple is expected to release an updated mobile operating system called iOS 14 in the fall. As part of the update, the smartphone maker is requiring apps to ask users for permission before collecting and sharing data using a unique code that identifies their mobile Apple devices. Called the advertising identifier or IDFA, this code makes it possible for businesses to better target ads and gauge whether they're working.
"For developers and publishers using Audience Network, our ability to deliver targeted ads on iOS 14 will be limited. As a result, some iOS 14 users may not see any ads from Audience Network, while others may still see ads from us, but they'll be less relevant," Facebook said in a blog post.
