• Amazon DSP multichannel products

The correct answer is: Amazon DSP multichannel products

Explanation: To reach shoppers who’ve browsed coffee makers, Shirley should use Amazon DSP multichannel products. Unlike Sponsored Products, which primarily target shoppers through keyword and product listing ads within Amazon, Amazon DSP (Demand-Side Platform) enables advertisers to reach audiences based on their browsing behavior both on and off Amazon. DSP utilizes Amazon’s rich first-party behavioral and purchase data, making it possible to retarget people who have looked at coffee makers, even as they browse other websites or apps. This extends engagement beyond Amazon’s retail platform, creating more touchpoints and improving conversion rates by following up with interested shoppers wherever they spend time online.
