An advertiser wants to exclude existing customers from their new-to-brand campaign. Which audience solution allows them to do this most effectively?

The correct answer is Advertiser audiences because this audience solution allows advertisers to create custom audiences based on their own customer data, which can include information about whether a customer is new or existing. By using Advertiser audiences, the advertiser can specifically exclude existing customers from their new-to-brand campaign, ensuring that the campaign reaches only new potential customers who have not yet interacted with or purchased from the brand. This level of customization is not easily achievable with Similar audiences or ASIN remarketing audiences, as these solutions focus on broader targeting based on behavioral data or past product interactions, but do not offer the same level of control over customer segmentation based on the advertiser’s specific customer lists.
