Define cross-channel attribution and mention a challenge.

• A. Reach Is The Number Of Unique Individuals Exposed At Least Once; Frequency Is The Frequency Cap Used to Limit Exposures.
• B. Assigning Value Across Multiple Channels to the Same Customer Journey; Challenge: Data Fragmentation and Model Complexity.
• C. Measuring Only the Last-Click Effect; Challenge: Ignoring Upper Funnel.
• D. Tracking Only TV and Print; Challenge: Limited Digital Data.

Answer: (B)

Cross-channel attribution is the process of assigning value to multiple marketing touchpoints across a single customer journey. It recognizes that a consumer may interact with several channels—TV, online search, social, email, and more—before converting, and it aims to credit each touchpoint for its contribution rather than just the final interaction. A key challenge in this approach is data fragmentation and model complexity. Data fragmentation happens when information sits in separate systems and platforms, making it hard to stitch a single, coherent view of the journey. Model complexity involves building attribution methods that fairly allocate credit across many touchpoints while handling the order, timing, overlaps, and cross-device behavior. For example, a shopper might see a TV ad, later search, receive an email, and then convert online; a robust cross-channel model must integrate data from all these sources to determine each touchpoint’s impact. Options focused on exposure counts, last-click credit, or tracking only a subset of channels don’t capture the multi-channel credit that cross-channel attribution seeks to provide.
