  • Create attribution models that factor in a multi-device, multi-step consumer journey, with multiple engagement points contributing to conversion.
  • Partner with brand teams and agencies to ensure campaigns have the right level of measurement planning, aligning on KPIs and success criteria, as well as consulting on in-flight optimizations.
