Meredith Corp. announced today it has partnered with The Trade Desk Inc., a global technology platform for buyers of advertising, to launch a data analysis tool the companies say will be the “next phase of data-driven marketing.” In pilot ad campaigns, the new service for digital shopper marketing delivered up to 19 times higher return on advertising and significant in-store sales increases across multiple retailers, Meredith said in a release. The Trade Desk will have exclusive access to Meredith’s programmatic shoppable display inventory on Allrecipes.com, with more than 45 million monthly unique visitors, as well as across Meredith Digital’s network of sites, including Bhg.com, Shape.com, and MarthaStewart.com.
