Currencies

Currently, all transactions (bids and invoicing) in the Triton Digital exchange are in USD.

Buyers cannot provide a bid in a different currency. If a bid is provided with a different currency it will be ignored from the auction.

Categories & Brands

For frequency capping and industry separation (crucial for ad breaks with multiple ads), the ad category (seatbid.bid.cat attribute) is required. The IAB24 category ("Uncategorized") is not allowed.

For ad quality purposes, a valid advertiser domain (seatbid.bid.adomain attribute) is required.

Bids that don't provide both a category and a valid advertiser domain will be ignored from the auction.

The "cat" field should only contain the value of the category (i.e., IAB1-1), not the name of the category (as per OpenRTB specification). The Triton Digital exchange will drop any bid that has anything other than valid category values in this field.

Buyer Identification

Buyer identification (seatbid.seat attribute) is required. When using numerical IDs, DSPs must provide Triton Digital with a map of ID-to-name.

Bids that don't provide a buyer ID will be ignored from the auction.

Audio Formats

  • MP3, WAV, WMA, or OGG format
  • 15- to 60-second duration (15 and 30 are most commonly used)
  • At least 128 kbps bit rate / 44100 Hz sample rate
  • Trimmed of slate/silence
  • Tracking: 1x1 pixel only

Banner Formats

Because of the variety of players in the marketplace, there is no guarantee that companion banners will be supported with all audio impressions. If displayed, banners don't incur any additional cost to the buyer because billing is based on the audio impression only. Banner views and click reporting are also not guaranteed.

Unlike the audio, banners are forwarded to the players as received by Triton Digital. All banner formats are supported (StaticResource, HTMLResource and IFrameResource).

For optimum player compatibility, we recommend the formats shown below:

Widely Used:

  • Medium Rectangle (300x250px) This is the most commonly used format for companion banners across all player formats.

Generally Used:

  • Leaderboard (728x90px) This common format is typically used for desktop (browser-based) players.

Occasionally Used:

(These less common formats are only used in mobile apps.)

  • Smartphone Static Banner (300x50px)
  • Smartphone Static Wide Banner (320x50px)
  • Spotify custom size  (640x640)

Banner formats:

  • GIF
  • JPEG
  • PNG
  • HTML, JavaScript,  or rich media (such as Flash)

Flash Restrictions:

  • Looping: 3 Times per served ad
  • Animation speed: 24 FPS
  • Maximum animation time: 7 seconds
  • Flash banners can be tracked when the industry standard "ClickTAG" tracking layer is used

Tracking:

  • 1x1 pixels only (no JS support)
