h3h3xxIntroduction to the Video SSP Marketplace for Sellers

ppxxThe Video SSP Marketplace provides sellers with a powerful and efficient system to sell online video ad inventory. Anyone with access to video inventory who wants to earn incremental revenue can be a seller: publishers, content management systems, even rep firms.

Sell inventory through marketplaces with a Marketplace Connection. A Marketplace Connection is a pipeline that connects a seller’s inventory to the Video SSP Marketplace and enables buyers to purchase this inventory in a programmatic fashion.


A seller may segment their inventory into multiple connections (even if the inventory is from the same site). 



Example: You could break up inventory by geo and apply different floorCPMs.

Basic ad request in Video SSP

Process Stage



The video player calls the Video SSP Marketplace and requests an ad.


The Video SSP ad player receives metadata for that ad request (including pageURL).


The ad player determines the marketplace connection to select based on that metadata.


The trouble with iFrames

Requests from video players that are received in iframes are not monetized because the page URL cannot be verified (only the iframe URL appears). Contact the Marketplace Team with issues.


Best practices for monetization

Connections approved for the Video SSP Marketplace must only contain sites with the same connection settings - including content type, ad initiation, video quality, placement type, ad sound, and language*.

Video SSP Marketplace publishers must agree to follow the acceptable practices outlined in the Video SSP Code of Conduct.

This table outlines the best practices to monetize and maximize potential marketplace impressions.

Monetize Seller’s Inventory

Monetize Buyer

  • Allow ad durations of at least 30 seconds. 50% of marketplace ads are 30 seconds long with companion banners
  • Accept companion banners
  • Support and use VPAID tags: Many buyers have shifted to VPAID ads because of its interactivity functionality
  • Set your reserve price at a low CPM possible. A lower price floor means more potential marketplace ad impressions are available for your inventory.
  • Accept RTB buyers: Approve all RTB buyers to increase competition from non-RTB marketplace buyers and potential ad impressions.
  • Select Auto Ad Approval for all buyers: Auto Ad Approval saves you time and immediately allows ad campaigns to start bidding on your inventory.
  • Enable RTB Buying
  • Enable Site-Level Reporting



Connections review process by Policy Team

The Video SSP Policy team reviews the connection to ensure the settings specified in the connection match exactly. The Video SSP Policy team must be able to find video content on the listed domain(s) and be able to verify the connection specifications. Connections with blocklisted or restricted sites or apps are automatically rejected.

All sites are vetted against our internal blocklist.

  • If a site listed in a connection is blocklisted, it is removed.
  • If one or more sites do not match the settings specified in the connection, Video SSP Policy will stop reviewing and reject the connection.
  • If a connection is altered or rejected during the approval process, the publisher will be notified by the Supply Operations  team via email. Additional policy related questions regarding video connections may be directed to
