BroadSign is a Supplier that provides programmatic access to Digital Out of Home (DOOH) inventory. They provide access to inventory internationally, with the heaviest concentration in US, CA, UK, and Australian markets. Screens are both indoor and outdoor, and support video and image based creatives. Prospective buyers should reach out to their Demand Manager to get connected.

What’s Different About It?

  • DOOH transacts in Plays, each play can be viewed by multiple people, yielding multiple impressions per play. BroadSign auctions plays, and provides information that allows buyers to extrapolate the estimated impressions per play.

  • The impressions-per-play relationship is defined by the publisher (screen owner) via the Audience Schedule tool in the BroadSign UI.

  • The dooh.impmultiply field value sent in the Bid Request is used to calculate the billable media cost to the Buyer and on the invoice. It should not be used to multiply the bid price in the bid response. See the DOOH Object for details.

  • A play will not always occur immediately after the auction. Buyers should expect up to 48 hours to elapse between winning an auction (signaled by a win notification to the buyer within 200ms) and a play occurring on the screen (signaled by an impression notification within 48 hours).

  • BroadSign runs auctions for video or image plays that occur on a particular screen.

  • Video plays will have a 100% completion rate, and screens are considered to be always “in-view”.

  • Creative Approval must be sought in advance of trading, and is handled per publisher. To seek Creative Approval buyers must have a login to the BroadSign UI.

    • BidSwitch is building support for the BroadSign Creative Approval Pre-registration API with an estimated live date of December 2016. This API will allow users to bypass accessing the BroadSign UI for creative submission and approval.

Managing A Campaign

  1. The campaign/line item is set up with the relevant Deal ID. The Deal ID can be found in the BroadSign UI.

  2. The Buyer receives a bid request containing this Deal ID.

  3. The Buyer responds with the standard video or image response format, see the Bid Response JSON Examples section for example.

  4. Buyers will bid on a bid request, which represents a Play; the Audience Schedule translates the Play to impressions based on Time and Date.

  5. For each auction, there will be a single win notification sent (within 200ms). The win notification is not indicative of a served impression, though win notifications and impressions should have minimal or no discrepancy after 48 hours has elapsed.

  6. The impression/play will occur no more than 48 hours following the auction.

  7. An impression notification is fired when the play actually occurs.


  • Buyer and Supplier reporting will have same-day reporting available through the myBidSwitch UI.

  • Same day reporting is reflective of auction wins, not plays.

  • Buyers should allow up to 72 hours for myBidSwitch UI reporting to show accurate impression (play) counts. The impression numbers reported here will not include the impmultiply value.

  • BidSwitch will record an auction win as an impression, even though a creative may not have been served yet. It may not be served for up to 48 hours after the auction win.


  • Financial data for Buyers (“Invoicing Report”) will be accurate, based off of impressions up to 48 hours after wins have occurred.

  • Buyer Finance reporting will record the auction date as the date the ad was served, and will bill based on the auction date.

  • The impmultiply value passed in the Bid Request will be used when calculating your invoice. For example, if you win 3000 bids at a clearing price of $1.50 CPM and impmultiply=4 each, then the invoiced amount is $18 (1.50 / 1000 * 4 * 3000).


On the myBidSwitch UI Reporting page, reporting shows impression figures without multiplying them by the impmultiply value, but the media cost is multiplied. So the above example will be shown as 3000 impressions with $18 media cost and $6 eCPM.
