問題文
A marketer's audience reports zero members. The criteria are: purchased in the last 30 days, opted in to email, and located in one city. Each condition on its own returns thousands. What is the diagnosis?
選択肢
- One of the three attributes is not mapped, because an unmapped attribute evaluates as false for every record and therefore reduces the population to zero regardless of the other conditions in the definition.
- The conditions are combined so that all of them must hold at once, and almost nobody satisfies the intersection.
- The segment has not been run since it was saved, because a definition without a completed run reports zero rather than reporting that no evaluation has taken place yet in the builder.
- The marketer is in the wrong data space, so the criteria are being evaluated against records that belong to another brand.
