Server-side tracking patches the pipe, not the measurement model

In short Moving data collection server-side doesn't restore user-level tracking, so measurement should rest on outcomes and aggregated groups rather than rebuilt individual journeys.

Digiday reports that ad tech is rallying behind IAB Tech Lab's Trusted Server Framework after Apple's latest Safari restrictions, though doubts remain.

I get why. Server-side feels like a way to get the old tracking back.

But moving the collection point doesn't change what you're allowed to see. Walled gardens still block access, and more than 90% of the user journey was already untrackable before this update.

Server-side is a stopgap. It patches a pipe, not the model.

What holds up:

  • Measure outcomes, not individual paths
  • Work with aggregated groups instead of user-level IDs
  • Retire last-click as your source of truth

Since the iOS change, I've said we're in a world of aggregated data. Apple's latest move is the final knife in user-level tracking.

If your plan depends on rebuilding the individual journey, you're funding a fool's errand with better plumbing.

Responding to Apple’s Safari crackdown pushes ad tech toward server-side solutions, but doubts remain, Digiday
