Facebook isn't happy about Apple's upcoming ad tracking restrictions

Apple’s upcoming operating system iOS 14 (currently in public beta) could have a big impact on publishers who work with Facebook’s ad network — at least, according to Facebook.The company published a couple of blog posts yesterday outlining the potential impact of a major privacy change that Apple announced at WWDC — namely, the fact that Apple will explicitly ask users whether they want to opt-in before sharing the IDFA identifier with app developers, who can then use it to target ads.In response, Facebook said it will not be collecting this data on its own apps, but it suggested that the bigger impact will be on the Facebook Audience Network, which uses Facebook data to target ads on other publishers’ websites and apps.“Like all ad networks on iOS 14, advertiser ability to accurately target and measure their campaigns on Audience Network will be impacted, and as a result publishers should expect their ability to effectively monetize on Audience Network to decrease,” the company said.
