Apple iOS 14 to severely hit our online advertising, says Facebook

Facebook has acknowledged that Apples upcoming iOS 14 may lead to over 50 per cent decline in its Audience Network advertising business.

Facebook Audience Network is an in-app advertising network for mobile apps.

The social networking app said on Wednesday that it will not collect the Identifier for Advertisers (IDFA) on its own apps on iOS 14 devices.

The IDFA is a random device ID number assigned by Apple to a user’s device. Advertisers use this to track data so they can deliver customised advertising. The IDFA is used for tracking and identifying a user (without revealing personal information).
