The marketing stack after the cookie: marketing mix modeling, incrementality testing, server-side tracking and agentic analytics — curated for CMOs and performance teams.
In short
Without third-party cookies, measurement rests on three complementary methods: marketing mix modeling for budget allocation, incrementality testing for causal contribution, and server-side tracking for dependable conversion signals. None replaces the others — last-click alone leads systematically to misallocation. The prerequisite is consistent metric definitions so the same figure is identical in every report.
For marketing this is about backing budget decisions again when click paths are incomplete - with models and tests instead of gut feel.
For engineering it is about server-side tracking, data quality, consent and a data foundation models can actually run on.
