Question: Which of the following best describes brand halo?
- Brand halo expands conversion attribution to all ASINs that have the same brand name(s) as the ASINs associated to the purchases
- Brand halo only assesses conversion attribution of ASINs promoted in a campaign
- Brand halo helps you understand which audiences are most likely to engage with your brand
or
- Amazon Publisher Direct
- Goal-based bidding
- Bid optimization models
Explanation
Brand halo measures the broader effect of advertising by including attributed conversions for products under the same brand as the promoted ASINs. This helps show whether media influenced purchases beyond the specific products featured in the campaign. In Amazon DSP, this matters because conversion reporting can distinguish promoted conversions from brand halo conversions. Bid optimization models can use campaign conversion signals to support performance-based delivery decisions.
Why the other options are incorrect
Option B is incorrect because brand halo is not limited to promoted ASINs.
Option C is incorrect because audience engagement analysis is not the function of brand halo.
Option D is incorrect because Amazon Publisher Direct is a supply access program, not a conversion attribution concept.
Option E is incorrect because goal-based bidding is an optimization setting, not the definition of brand halo.
