Which field could be used to segment customers in an online sales dataset?

• A. City
• B. Shipping method
• C. Campaign code
• D. Order date

Answer: (C)

Segmenting customers means grouping them into meaningful categories based on attributes that influence their purchasing behavior. A campaign code attaches to each order to indicate which marketing effort led the customer to buy. By using campaign code as the basis for segmentation, you can compare how different campaigns perform, measure metrics like conversion rate and revenue per campaign, and tailor marketing strategies accordingly. The other fields describe geography (city), fulfillment (shipping method), or timing (order date) rather than which marketing stimulus influenced the sale, so they’re less direct for segmentation aimed at marketing attribution and optimization.
