Targeting Microsoft video inventory

Each video inventory type can be targeted using RTB or Deals. To target Microsoft video inventory, follow the guidelines listed in the table below:

Targeting Method Guideline
RTB - For MSN: In your inventory list, include the domain. For more information, see Buying MSN Inventory.
- For Windows: In your inventory list, target Windows AppNetwork (348882). For more information, see Buying Microsoft Windows 3rd Party AppNetwork Inventory.
Depending on market availability, buyers can also target the In-stream and Outstream video position as described in Video Targeting.
Deals - Contact your Verizon representatives if you want to target deals in the following markets: US, Canada, UK, Germany, Spain, Italy, France, Brazil, and Japan.
- Contact your Microsoft Advertising account representative if you want to target deals in the following markets: Austria, Belgium, Denmark, Finland, Ireland, Netherlands, Norway, Portugal, Sweden, Switzerland, and all emerging markets.
External Bidder - When targeting, add to the targeted domain list using the Inventory List Item Service. All MSN domains will be captured by the parent domain.
- When targeting video bid requests, we highly recommend that bidders listen to the Video AppNexus Object within the Video Extension Object to distinguish In-stream, Outstream, and Bannerstream bid requests. Without listening to this object, it is difficult to differentiate Bannerstream inventory since Bannerstream is a proprietary Microsoft Advertising format.


Information the user should notice even if skimming If you choose to filter by creative size, the list of creative sizes must be exhaustive. Include 1x1 as a permitted size since all of our video inventory appears as 1x1. For more information, see our Bidder Profile - FAQ.
