What advertiser insights can you use to build lookalike audiences?
Explanation: The correct answer is **All of these** because you can use all of the listed advertiser insights to build lookalike audiences. Amazon DSP allows advertisers to create lookalike audiences based on various sources of data, which can include AAt-based audiences (audiences built from the data captured by the Amazon Advertising tag), advertiser hashed-customer lists (lists of customer data that are hashed for privacy protection), and DMP-transferred audiences (audiences transferred from a Data Management Platform). Each of these data sources can be leveraged to find new users who share similar behaviors or characteristics to the advertiser’s existing audience, thereby improving targeting and campaign performance. By combining these insights, advertisers can build more effective and precise lookalike audiences that help expand their reach to relevant, high-potential users.
