The authors explain that current methods to measure marketing impact either give broad channel-level results or detailed but less reliable campaign data due to privacy limits. They introduce Integrated Marketing Attribution (IMA), which combines the strengths of both methods by using broad-level insights to guide detailed campaign analysis. This approach provides more accurate and privacy-friendly campaign measurements while staying consistent with traditional methods. Essentially, their work helps marketers see which campaigns work without tracking individual users.

Abstract
Retail marketing measurement increasingly requires granular campaign-level insights without relying on user-level tracking. However, the two dominant approaches, Marketing Mix Modeling (MMM) and Multi-Touch Attribution (MTA), often produce fragmented insights. MMM is privacy-safe and robust for channel-level planning but is too coarse for campaign optimization, while MTA provides granular attribution but has become less reliable under increasing privacy restrictions. We propose Integrated Marketing Attribution (IMA), a unified framework that combines MMM with channel specific Bayesian attribution models to derive campaign-level effects from aggregated data. By leveraging MMM-informed priors, IMA delivers granular, privacy-safe attribution while preserving consistency with MMM.
