Your client’s CEO asked their CMO for the revenue contribution and ROI of last year’s total marketing budget. The CMO’s annual marketing portfolio included online and offline channels, across both brand and performance media. Which measurement solution should the client use?

Marketing Mix Modeling (MMM) is the correct measurement solution for this scenario because it is specifically designed to provide a high-level, holistic view of a company's total marketing portfolio, capturing the revenue contribution and ROI of both online and offline channels. Unlike attribution models that are limited to digital click-path data, MMM uses advanced statistical analysis to correlate historical marketing spend with sales outcomes while accounting for external variables like seasonality and economic trends. This makes it the ideal "top-down" approach for a CMO to justify an annual budget to a CEO, as it can evaluate the long-term effectiveness of broad brand-building efforts alongside direct performance media across all touchpoints in a unified report.
