Quotes
(10:20) “One of the big things that also everybody is aware of is with Apple and the privacy changes with ATT in 2020, 2021, when they launched it, there was a big shift in the whole industry.”
(12:27) “With all the technology that is out there and what is capable, AI is one of the biggest drivers to just get better.”
(16:42) “AI just gets better and better, so even without a clear 100% deterministic match, you’re still able to get good retention and good results for retargeting campaigns on iOS specifically.”
Appleが提供するプライバシーフレームワークで、iOSデバイスに割り当てられるデバイス固有の識別子であるIDFA(Identifier for Advertiser)にアクセスする前に、ユーザーからトラッキングの諾否を得るプロセスを管理する仕組み。2021年4月にリリースされたiOS14.5より導入された。ユーザーの許諾が得られない限り、広告主は、IDのトラッキングができず、パーソナライズ化された広告配信などができなくなる。
