The Wall Street Journal reports on the potential advantages advertisers could receive by buying advertising space through Apple following the launch of its App Tracking Transparency framework. According to ad industry executives, when targeting users who have opted out of tracking, advertisers will have to wait days to receive aggregate information when buying through third-party platforms. By purchasing ad space with Apple, advertisers will receive more data on user behavior in real-time, which could give the technology company an advantage in attracting more interest to its platform.
