One of the job postings says that product sampling is an advertising product that “leverages Amazon’s customer data to allow brands to put their products in the hands of the right customers to drive product awareness and conversion.” It also claims the team is operating as “a true start-up” that is “reinventing” how customers discover new products.

The other ad says free samples are more likely to ensure that shoppers will buy a product than traditional display ads. As Axios rightly points out, the sample strategy—which works well for companies like Sephora—gives Amazon a massive advantage in the digital advertising market over its main rivals, Facebook and Google, who don’t have the same infrastructure to ship out a product a user had browsed or clicked on.
