Key points from Digiday’s report

  • Addressability and measurement restrictions have resurfaced as a top concern for ad tech professionals, following Apple's iOS 27 updates and court-ordered integration proposals between Prebid and Google's ad tech.
  • Industry experts predict that the challenge of addressability and anonymity will continue to dominate discussions at future industry gatherings, as the open web faces limitations compared to walled gardens like Apple and Google.
  • Publishers are adopting strategies similar to Meta's in response to Apple's policy changes, building decision-making and audience intelligence onto the supply side to mitigate the impact of unilateral policy decisions from gatekeepers.
