Sponsored Display is an advertising campaign that allows your company to reach those shoppers that viewed your product in the past but never ended up buying it. We can consider Sponsored Display ads a way to reach a wider audience, as we can find them both on and off Amazon.
This advertising campaign is based on the audience's interests, their sales behavior, and the fact that they have already visited your product page in the past.
The shopper only has to click on the Sponsored Display ad to be directed on the product detail page, either he finds it on or off Amazon.
