Ursus is interested in expanding reach of their ads beyond Amazon O&O. Which supply source would you recommend they consider?

The correct answer is SSP and exchange inventory and/or Amazon Publisher Direct because both SSP (Supply-Side Platform) and exchange inventory, as well as Amazon Publisher Direct (APD), offer opportunities for expanding ad reach beyond Amazon's owned and operated (O&O) properties. SSP and exchange inventory allow access to a wide range of third-party websites and apps, significantly broadening the scope of an ad campaign. Meanwhile, Amazon Publisher Direct provides access to premium inventory from Amazon's direct partnerships with publishers, enabling advertisers to reach users across both Amazon's O&O properties and external publisher sites. Combining these two supply sources gives advertisers like Ursus the flexibility to maximize their reach across multiple platforms, ensuring a broader and more diverse audience for their campaigns.
