Question: Which of these are examples of signal inputs that can used within a clean room?
- Campaign impression logs
- Competitor pricing data
- Aggregated market share reports
Explanation
Amazon Marketing Cloud uses privacy-safe event-level advertising signals for analysis. Impression activity is a valid media signal because it records ad exposure that can be connected to downstream events in aggregated outputs. These signals help answer measurement questions such as reach, overlap, and path to conversion. Clean room workflows depend on available connected datasets rather than unrelated business reports.
Why the other options are incorrect
Competitor pricing data is incorrect because competitor price information is not an AMC advertising signal input.
Aggregated market share reports is incorrect because market share summaries are external business reports, not event-level clean room signals.
