Ha Yoon is an advertiser at a cold brew coffee manufacturer.Which audience would be best for her to use to reach these shoppers on Amazon that herbrand already has a direct relationship with off Amazon?

Advertiser hashed audiences are the best choice because they allow Ha Yoon to upload her existing customer data (e.g., email addresses) directly to Amazon in a privacy-safe, hashed format. Amazon then matches these hashed identifiers to its user base, enabling Ha Yoon to target her known off-Amazon customers on the Amazon platform. This directly addresses the need to reach shoppers with whom her brand already has a direct relationship. Demographic audiences (like age, gender, or income) are too broad and don't specifically target existing customers. Lifestyle audiences (based on interests or behaviors) are also too general and don't leverage the direct relationship Ha Yoon's brand already has with these shoppers.
