Which of the following strategies has been shown to increase reach of high-intent shoppers by 10 times?

Adding display ads to complement a sponsored ad campaign has been shown to increase reach to high-intent shoppers by 10 times. Display ads, particularly those on Amazon DSP, allow advertisers to reach audiences both on and off Amazon, including those who have viewed product detail pages but haven't yet purchased. This broadens the campaign's touchpoints beyond the search results page. While using both Sponsored Products and Sponsored Brands is a good strategy for comprehensive on-Amazon presence, it doesn't offer the same exponential reach expansion as display ads across the broader internet. Out-of-home custom solutions are generally for brand awareness rather than direct reach to high-intent online shoppers.
