Retail Media Manager vs. Marketplace Manager: What's the Difference?
Two roles that increasingly overlap, and increasingly need to be filled by two different people as retail media budgets grow.
Two roles that increasingly overlap, and increasingly need to be filled by two different people as retail media budgets grow.
As retail media has grown from a line item into its own budget category, we've seen more companies split what used to be a single Marketplace Manager role into two: a Marketplace Manager focused on operations and channel growth, and a Retail Media Manager focused specifically on advertising strategy and spend.
A Marketplace Manager typically owns the health of the channel itself: listings, inventory availability, fulfillment method, and overall channel P&L. A Retail Media Manager owns the paid media layer on top of that channel: Sponsored Products, Sponsored Brands, Display, and increasingly off-platform retail media networks tied to Amazon, Walmart, and Instacart data.
| Marketplace Manager | Retail Media Manager | |
|---|---|---|
| Primary focus | Channel operations and growth | Paid media strategy and spend |
| Owns inventory and fulfillment | Yes | No |
| Owns advertising budget | Sometimes | Yes |
| Reports on | Channel revenue and margin | ROAS, ACOS, and incremental sales lift |
If your marketplace advertising spend has grown to the point where it needs dedicated strategy rather than being managed as a side task by whoever runs the channel, that's usually the signal to split the role. Companies running significant spend across multiple marketplaces, not just Amazon, tend to see the clearest return from a dedicated Retail Media Manager.
Smaller teams often combine both functions into a single Marketplace Manager, which works fine until advertising complexity outgrows what one person can manage alongside operational responsibilities.
Most smaller teams start with a combined Marketplace Manager role and split out a dedicated Retail Media Manager once advertising spend and complexity grow enough to justify it.
Yes, Retail Media Manager is one of the core roles within our Marketplace Management practice area.
We see this most often in Beauty, Electronics, Home Goods, and Consumer Product Goods companies running significant spend across Amazon, Walmart, and Instacart.
