Paid Media Attribution in a Cookieless World
Third-party cookie deprecation and iOS privacy changes broke a lot of attribution models that marketing teams still quietly rely on.
Rebuilding measurement around what's actually still reliable is now a prerequisite for spending paid budget responsibly.
Key Points
Server-side tracking
Conversion data sent directly from the server, not dependent on a browser cookie surviving the session.
First-party data foundations
CRM and email data as the anchor for audience building, not third-party pixels.
Media mix modeling
Statistical modeling to fill the gaps that click-based attribution can no longer see.
Realistic incrementality testing
Holdout tests to confirm spend is actually driving incremental revenue, not just claiming credit for it.
