Question: Which KPI measures unique exposures from the start of a campaign?
- Click-through rate (CTR)
- Frequency
- Reach
Explanation
Reach measures the number of unique users exposed to an ad during a campaign. It is used for awareness planning because it shows audience scale rather than repeated exposure. Amazon Ads pairs this with frequency to understand both how many people were reached and how often they saw ads. This makes it the relevant KPI when evaluating unique exposure from campaign start.
Why the other options are incorrect
Click-through rate (CTR) measures the percentage of impressions that generated clicks, not unique exposure.
Frequency measures repeated ad exposure per user, not the number of unique users reached.
