Shirley is using Sponsored Products to engage shoppers looking for "coffee maker." To reach the shoppers who've previously browsed coffee makers, which of the following products should Shirley use?

The correct answer is Amazon DSP because Amazon DSP (Demand-Side Platform) allows advertisers to target shoppers who have previously browsed or shown interest in specific products, such as coffee makers, even when they are not currently on Amazon. This retargeting capability is ideal for reaching those customers who have already interacted with similar products but may not have made a purchase yet. By using Amazon DSP, Shirley can show her ads to these shoppers across different platforms, increasing the chances of converting previous visitors into buyers, making it a more effective choice than other options like Sponsored Brands or Sponsored Display for retargeting.
