Sell-Side Hierarchy Overview

This guide details Commerce Grid's sell-side hierarchy.

Knowing how sell-side objects are connected on our platform will help you make the right decision in mapping your domains/app bundles with ad units.


  1. Account is the highest-level hierarchy entity representing an end client (supply partner) for Commerce Grid, a publisher, or a publisher network.

  2. Accounts sort inventory into Inventory Groups to break up their supply by any of the following principles:

    • Integration type - Each integration connection with Commerce-Grid will have a separate inventory group. Amazon TAM integrations should run under a separate Inventory Group vs. Prebid.js, Prebid Server, or any other integration types.

    • Ads.txt entry - If you want to run a portion of inventory under a separate Pub ID, this is a viable use case for Pub Networks with some major publishers willing.

    • Inventory types or media type - though Commerce Grid provides granular reporting that allows accessing these dimensions, some publishers may still want to create separate Inventory Groups

  3. Ad Unit is the smallest sell-side object. An ad unit represents an ID mapping to a single physical slot or, in some cases, multiple physical slots that ads can run on. The ad unit IDs need to be populated in the bid request (either the integration type is header bidding or tags) for our platform to identify the source of the traffic.

  4. Domains/App Bundles correlate 1:1 with the domains or app bundles you monetize.
