An advertiser selling products in the Amazon store implements Amazon Ad Tag (AAT) on their external website. What is the primary benefit of this strategy?

The correct answer is Creating custom audiences for Amazon Ads campaigns based on external website behavior because by implementing the Amazon Ad Tag (AAT) on an external website, the advertiser can track user interactions and behaviors on that website, such as page views, clicks, and other actions. This data is then used to create custom audiences that can be leveraged in Amazon Ads campaigns. These audiences are highly relevant because they are based on actual user behavior, allowing the advertiser to retarget or engage with users who have shown interest in their products but have not yet converted. The other options, such as enabling direct purchases or optimizing product prices, are not directly related to the primary benefit of using AAT, which focuses on audience creation and behavioral tracking for more effective targeting in Amazon Ads campaigns.
