Case Study: The Book Outlet achieves 3.32x ROAS and 27% better eCPA with StackAdapt Dynamic Native Retargeting

Dynamic Native Retargeting drives READ-ICULOUSLY Amazing Return on Ad Spend with Book Lovers

The Book Outlet, a discount bookseller with over 90,000 titles, needed to better engage price-conscious readers and convert browsers into buyers while hitting an eCPA goal of $25. To do this, agency 9thCO ran Site-Wide and Dynamic Native Retargeting on the StackAdapt platform, using Dynamic Native Retargeting to surface relevant inventory and highlight the outlet’s low prices.

Using StackAdapt’s Dynamic Native Retargeting, 9thCO rotated eight personalized creatives that dynamically swapped book covers, headlines and prices to match visitors’ interests; this approach delivered a 3.32x ROAS, achieved 27% better eCPA than the $25 target, and produced those results within just 50% of the campaign flight.
