  • Partner with cross-functional teams and external vendors to develop and evolve Media Mix Models (MMM), translating model outputs into actionable recommendations for budget allocation and long-term investment planning.
  • Develop and apply attribution methodologies, including last-touch and multi-touch attribution, while understanding their strengths, limitations, and appropriate business applications in an increasingly privacy-first ecosystem.
  • Build forecasting models to predict channel performance, customer acquisition, revenue, and marketing efficiency, supporting annual planning and investment decisions.
  • Define measurement frameworks, instrumentation requirements, and success metrics for new campaigns, product launches, and strategic initiatives.
  • Partner with Lifecycle Marketing and CRM teams to measure customer journeys, email performance, retention initiatives, and customer engagement.
  • Measure and optimize organic acquisition strategies across SEO while helping shape measurement approaches for emerging search experiences, including Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO).
  • Translate complex analyses into clear, concise recommendations that influence senior leaders and drive business decisions, even when data is incomplete or evolving.
  • Champion automation, scalable analytics solutions, and continuous improvement across marketing measurement processes.
