A household goods company wants to understand how to allocate marketing spend across its portfolio of brands and media channels. It wants to compare the return on ads spend (ROAS) from Pinterest vs. other media channels. Which measurement solution should the media planner recommend?

To understand how to allocate spend across an entire portfolio of brands and multiple media channels (both digital and offline), Marketing Mix Modeling (MMM) is the industry-standard recommendation. Cross-Channel Comparison: Unlike Lift studies, which typically focus on a single platform in isolation, MMM uses high-level, aggregate historical data to compare the ROI/ROAS of Pinterest against TV, Search, Social, and Print. It provides a "single source of truth" for the entire marketing mix. Top-Down Allocation: MMM helps leadership decide how much to invest in each channel by identifying which platforms are driving the most incremental sales and where spend has reached a point of "diminishing returns." Privacy-First and Holistic: Because MMM does not rely on individual user tracking (cookies), it is resilient to privacy changes. It also accounts for external factors like seasonality, economic trends, and price changes that single-platform tools ignore.
