Until now, apps have been able to rely on Apple’s Identifier for Advertiser (IDFA) to track users for targeting and advertising purposes. With the launch of iOS 14.5 this week, mobile apps now have to ask users who have upgraded to iOS 14.5 for permission to gather tracking data. With opt-in rates expected to be low, this change is expected to create challenges for personalized advertising and attribution, impacting the $189 billion mobile advertising industry worldwide.
The numbers so far is 96% opt-out in the US, 88% opt-out worldwide.
I’m curious to know which countries have the highest opt-in rates.
