Onsite, Offsite, and In-Store Retail Media: The Ad Format and Channel Playbook (2026)
Retail media runs across three channels. Onsite is advertising on the retailer's own website, app, or search results. Offsite is the retailer's first-party shopper data activated on inventory the retailer does not own, including social platforms, the open web, and connected TV. In-store is advertising inside the physical store, including digital screens, retail audio, and QR-linked experiences. Each channel carries different ad formats, a different buying model, a different pricing basis, and a different way of proving that an ad drove a sale.
