Which inventory is available for Sponsored Products and Sponsored Brands campaigns?

Sponsored Products and Sponsored Brands campaigns primarily display ads on Amazon retail sites, such as Amazon.com, Amazon.co.uk, and other country-specific Amazon domains. These campaigns are designed to promote products directly to shoppers browsing or searching on Amazon. Third-party sites are generally part of Amazon DSP (Demand-Side Platform) inventory, not directly available for Sponsored Products or Sponsored Brands. Amazon O&O (Owned and Operated) sites can include a broader range of Amazon properties beyond just the retail sites (e.g., IMDb, Twitch), and while some ad formats might appear there, the core inventory for Sponsored Products and Sponsored Brands is specifically the Amazon retail environment.
