Amazon does targeted advertising through a variety of methods, most notably through its Amazon Advertising Services platform. This self-service platform allows businesses to create and run ads on Amazon.com and across Amazon’s network of sites. Advertisers can target shoppers based on their search terms, purchase history, and demographics. Amazon also offers Sponsored Products, which are ads that appear in search results and on product pages, as well as Amazon Advertising Brand Registry, which helps brands reach Amazon shoppers with more relevant ads.
