Apple's privacy push: Publisher ad revenue in trouble


14 October 2021

Apple’s latest software update continues its drive to limit the data that can be collected about iPhone users as they browse the internet. Prior changes have had an effect on ad prices for publishers, and on advertiser results

The new changes target cornerstones of profiling and targeting: IP and email addresses. The impact will be gradual, but could be profound if takeup is high

The lesson for publishers is that no technical implementation of targeted advertising is safe. Layering third-party data on top of anonymous audiences is not a future-proof business model
