Question: Which of the following best describes brand safety pre-bid targeting?
- Advertisers can choose which categories to reach based on their own brand safety requirements
- The context within which the ad appears
- Viewability of the ad
Explanation
In Amazon DSP, brand safety controls help advertisers avoid inventory that does not meet their suitability standards. Pre-bid targeting applies those controls before a bid is placed, so unsuitable impressions can be filtered out earlier in the buying process. Category selection lets advertisers align delivery with brand-specific tolerance levels. This is different from measuring where an ad appeared after delivery or evaluating whether the ad was viewable.
Why the other options are incorrect
Option B refers to placement context, not the pre-bid control used to filter inventory.
Option C refers to viewability, which measures whether an ad had the opportunity to be seen.
