Achieved a 27% lower eCPA than campaign goal

Book Outlet caters to book-lovers who want to be enriched, educated and entertained, but who also love a good bargain! Bibliophiles will find a wide, varied and diverse selection of hidden treasures in new condition and at fantastic prices. Over 90,000 titles are available online at read-iculously low prices.

The Challenge

Book Outlet needed a way to target returning users to their site and encourage them to convert, in a way that was less intrusive and much more appealing than a standard display ad. This new campaign would need to showcase the best book selections Book Outlet has to offer in a way that was personalized and engaging to users.

The Solution

9thCO ran site-wide Native and Dynamic Native Retargeting campaigns and created highly personalized ads to target returning visitors and encourage them to convert. Using this retargeting model, eight creatives remained in rotation, which dynamically replaced the image with the relevant book cover, as well as the headline with a CTA referencing the book title, and the body copy which included the impressively low price. The eCPA goal of this Dynamic Native Retargeting Campaign was $25.
