Who this is for
This guide is for curators who want to discover publisher-created supply packages and activate them by linking them to Demand Deals without rebuilding inventory targeting from scratch.
What you'll achieve
By the end of this guide, you'll know how to:
Discover Marketplace Supply Packages (MSPs) in the Trading UI
Evaluate a package before linking it
Link an MSP to an existing Demand Deal
Create a new Demand Deal from an MSP
Combine multiple MSPs in one deal, or reuse one MSP across multiple deals
Understand what happens when a linked package changes
Before you start
You must have access to the Trading UI in Commerce Grid.
Your account must be enabled for Supply Marketplace. Confirm this with your Criteo representative.
What is the Supply Marketplace?
The Supply Marketplace is a discovery and activation layer inside the Commerce Grid Trading UI that lets you browse publisher-created supply packages and link them directly to your Demand Deals.
Instead of assembling deal inventory manually, you can:
Browse pre-packaged supply from publishers across Commerce Grid
View metadata (seller, format, geo, pricing floor) before committing
Link packages to new or existing Demand Deals in a few steps
Reuse a single package across multiple deals, or combine multiple packages in one deal
This is not a separate platform. It is built into the Trading UI you already use.
Marketplace-enabled deals are also eligible for lower platform fees (4–6%), creating a direct commercial incentive for adoption.
1. Discover Marketplace Supply Packages
Open the Trading UI in Commerce Grid.
Navigate to the Supply Marketplace section.
Browse available packages. Use the search and filter tools to narrow results by:
Seller / publisher
Pricing floor
Inventory type
Geo targeting
2. Evaluate a package
Before linking a package to a deal, review its metadata:
Field | What it tells you |
|---|---|
Publisher / Seller | Who is providing the supply |
Inventory type | Format (display, video, native, etc.) |
Formats | Specific ad formats included |
Geo targeting | Markets or regions covered |
CPM pricing floor | The minimum price accepted by the publisher |
Pricing floors are set and enforced by the publisher. You cannot override them.
3. Activate supply
Once you've identified a package, you can activate it in two ways:
Link to an existing Demand Deal
Select the Marketplace Supply Package.
Choose Add to existing Demand Deal.
Select the deal from your available deals list.
Confirm the linkage.
Create a new Demand Deal from an MSP
Select the Marketplace Supply Package.
Choose Create new Demand Deal.
Configure your deal terms (name, DSP, targeting, etc.).
Save and activate the deal.
4. Combine supply across deals
The Supply Marketplace supports flexible linking patterns:
Pattern | How it works |
|---|---|
Multiple MSPs > One deal | Attach several Marketplace Supply Packages to a single Demand Deal to combine publisher supply |
One MSP > Multiple deals | Reuse a single package across multiple Demand Deals (for example, across different client seats) |
You can also combine Marketplace supply with your own proprietary supply within a single deal.
Monitoring deal status and performance
After linking an MSP to a deal, monitor status and delivery from within the Trading UI:
Performance indicators available- Win rate, eCPM, impressions
Reporting granularity- Available at the deal level for Marketplace-linked supply
What happens if a linked package changes?
Event | What happens to your deal |
|---|
Event | What happens to your deal |
|---|---|
Package is updated by the publisher | Deal remains active; status update is reflected in the UI |
Package is deactivated or unpublished | Deal remains active but supply from that package stops delivering |
Package is deleted by the publisher | Deal remains active; you will need to find alternative supply |
Your Demand Deal is never automatically deactivated by a publisher action. Delivery may stop for the affected supply, but the deal itself stays active.
Frequently asked questions
Is the Supply Marketplace a separate trading platform? No. It is a discovery and activation layer built directly into the Commerce Grid Trading UI.
Can I use one Marketplace Supply Package across multiple deals? Yes. A single MSP can be linked to multiple Demand Deals, including deals across different client seats.
Can I combine multiple MSPs in one deal? Yes. You can attach multiple Marketplace Supply Packages to a single Demand Deal.
What happens if the publisher deactivates a package I'm using? Your Demand Deal stays active, but supply from that package stops delivering. The status change is reflected in your UI.
Can I negotiate the CPM floor with the publisher? No. Pricing floors are set by the publisher and strictly enforced. Deal terms (beyond the floor) are negotiated separately between you and the publisher.
Will my billing change if I use Marketplace supply? No. Existing billing and invoicing rails apply. Marketplace-enabled deals are eligible for lower platform fees (4–6%).
Can I see publisher-specific financial terms? No. Only essential metadata and deal-level performance data are visible to curators in the current release.
