¿Cuál de las siguientes audiencias puede crearse a partir de las audiencias actuales de los anunciantes, y aprovechar los algoritmos de aprendizaje automático para ayudar a llegar a nuevas audiencias con características similares?

Similar audiences, also known as lookalike audiences, are created by Amazon's machine learning algorithms to identify new customers who share characteristics with an advertiser's existing customer base or other seed audiences. This allows advertisers to expand their reach to prospects likely to be interested in their products. Demographic audiences are based on general characteristics like age, gender, and income, not derived from existing customer data in the same way. Amazon audiences are broad categories of users based on their shopping and browsing behavior on Amazon, but "similar audiences" specifically refers to the algorithmic expansion of an existing audience.
