Which is the most significant benefit of using Amazon DSP for brands that do not sell their products in the Amazon store?

The selected answer Reach incremental audiences by serving ads across a wide network of websites and apps is correct because one of the most significant benefits of using Amazon DSP for brands that do not sell products on Amazon is its ability to reach new, incremental audiences. Through Amazon DSP, brands can serve ads across a broad network of third-party websites, mobile apps, and other digital platforms. This allows them to expand their reach beyond the Amazon ecosystem, targeting potential customers who may not have interacted with the brand on Amazon. This is particularly valuable for brands that do not have a presence on Amazon's marketplace, as it enables them to drive awareness and interest among a wider audience, helping to grow their customer base and build brand recognition across the web.
