What is offsite retail media?
Offsite retail media refers to advertising that a retailer sells using its first-party audience data but serves outside of its owned properties — on the open web, social platforms, streaming services, or third-party publisher sites. Unlike onsite retail media (ads on a retailer's own website or app), offsite retail media extends the retailer's data advantage beyond their walled garden to reach consumers wherever they are.
Onsite vs. offsite retail media
Onsite retail media reaches consumers who are already shopping on a retailer's platform — high intent, but limited to that retailer's owned audience. Offsite retail media applies the retailer's purchase and behavioral data to reach consumers in contexts outside the retailer's owned environment, dramatically expanding reach while maintaining the data precision that makes retail media valuable.
