Scenario

You work on a shopping platform where a product is featured on-air and digital sales rise shortly after the segment airs. Leadership wants to know whether the lift was actually caused by the on-air feature or just reflected normal demand shifts. You need to separate correlation from causation before the team changes how features are scheduled.

Question

How would you determine whether the lift in digital sales after the on-air feature was actually caused by the feature? What experiment design, metrics, and analysis would you use to make that call?
