Apple has reopened its feud with ad tech companies over identifying people on its devices, according to Digiday. The latest software update for iPhones has blocked several identity vendors, including ID5, LiveRamp, and Permutive.
Apple's block affects publishers, with browsers built on WebKit accounting for 30% of ad impressions and 28.5% of ad revenue. The update has led to a decrease in bid rates, with iOS bid rates falling 14% between September 15 and October 8.
The block may have significant consequences for the ad tech industry, with some companies already feeling the effects. The Trade Desk's ads stopped loading in the Safari browser initially, but the company has since received a reprieve.
Apple's move is seen as a push towards contextual advertising, where ads are targeted based on the content around them rather than individual user data. OpenX's numbers suggest that this shift is already underway, with buyers increasingly targeting ads based on content characteristics.
Permutive, one of the blocked companies, argues that the focus on IDs has been overemphasized. The company claims that IDs only cover about 30% of the bid stream, leaving a significant portion of publisher audiences unsold.
Apple's ad revenue is growing, albeit slowly, with the company expected to rake in $9.05 billion in 2026, according to eMarketer. The tech giant's ads business is becoming increasingly important, as it sits inside the services segment, which now accounts for 43% of Apple's growth profit.
