Ana wants to run a campaign to audio publishers around the world. Which ad channel should she use?

The correct answer is Amazon Publisher Direct because this ad channel is specifically designed for advertisers looking to reach audio publishers and their audiences globally. It provides a platform for distributing audio ads effectively across various channels, allowing advertisers like Ana to connect with listeners in a targeted manner. In contrast, Amazon Music is focused on music streaming and its advertising options primarily cater to that medium, while Amazon Prime Video is centered around video content, making Amazon Publisher Direct the most suitable option for running a campaign targeting audio publishers.
