The day-to-day work involves auditing existing media measurement practices, building dashboards to track key performance indicators, and presenting data-driven narratives to senior stakeholders to guide future budget allocation and strategy. These experts are often tasked with evangelizing a culture of evidence-based marketing, moving organizations from last-click attribution to more nuanced models that account for cross-channel influence and long-term brand building.

They must have exceptional analytical skills, with experience in statistical analysis, data modeling, and familiarity with analytics platforms and data visualization tools. Crucial soft skills include stellar communication to demystify data, project management to coordinate multifaceted initiatives, and a problem-solving mindset to tackle ambiguous marketing challenges.
