The article argues that while Marketing Mix Models (MMMs) are essential for evaluating CTV performance beyond last-click attribution, they lack the granularity to explain specific campaign outcomes. It recommends using MMMs as high-level calibration tools while employing deeper diagnostic data to analyze network, audience, and creative variables.
The shift toward CTV marketing mix models signals a necessary departure from search-based metrics that fail to capture how streaming video influences the broader funnel. By moving away from accidental click data, brands can better justify spend to finance teams through independent incrementality reporting. However, the ecosystem risks oversimplification if executives treat these high-level models as final arbiters rather than diagnostic starting points. As fragmentation increases across inventory paths, the industry must balance broad accountability with specific technical analysis of audience composition and frequency. Watch for whether major platforms provide more granular data exports to improve the accuracy of these third-party models.
Marketers are increasingly adopting marketing mix models (MMMs) to measure CTV performance, moving away from flawed last-click attribution. While these models effectively track incremental growth and marginal impact, they often lack the granularity to distinguish performance between specific platforms, necessitating a two-step approach that combines high-level modeling with detailed diagnostic analysis.
MMMs provide a broader view of incremental impact in non-clickable channels, helping brands move beyond search-based metrics that fail to capture how streaming video influences the broader marketing funnel.
Treating CTV as a single channel in models can obscure performance disparities across hundreds of networks and audience segments, making it difficult to explain specific campaign outcomes.
Effective measurement requires a two-step sequence: using MMMs for high-level contribution analysis followed by granular diagnostics to evaluate specific network and creative variables.
Geo-testing remains vulnerable to contamination caused by imperfect location signals and leakage from cross-device matching.
