Retail Media Advertising platforms manage paid advertising on retail-media networks — Amazon Ads (Sponsored Products, Sponsored Brands), Walmart Connect, Instacart Ads, Target Roundel, and the growing universe of retailer-owned ad networks. The category emerged as eCommerce brands shifted advertising spend to where consumers actually shop. Core capabilities include unified campaign management across multiple retail networks, automated bidding for retail-media ad units, keyword and product targeting, share-of-voice and ranking analysis, and attribution to in-marketplace sales. The market spans retail-media specialists (Pacvue, Perpetua, Skai for retail/Commerce Media, Teikametrics) and broader retail-media networks and DSPs (Criteo, Topsort, Quotient).
