‘VAST to RTB’, ‘VAST to VAST’, and ‘VAST To All’ Trading Is Now Available in SmartHub

8 reviews

We know that it can be a challenge when you have different kinds of demand and supply partners in your marketplace. Each of them may trade according to particular standards and protocols. For instance, most often partners trade within the same connection type – RTB to RTB or let’s say VAST to VAST. However, if your system also supports VAST to RTB, RTB to VAST, and VAST to all connections it gives your partners much more flexibility and media-trading convenience. Let’s see how it becomes possible in your SmartHub.

Getting down to basics

There’s no need to go on about the technical subtleties of each protocol or explain how each one can be very important for media trading and rendering certain creatives. At the same time, we’d like to give you a little reminder of those protocols that we are going to talk about:

  • Video Ad Serving Template (VAST) is a video serving protocol developed by IAB. In simple words, VAST helps ad servers and video players communicate with each other to effectively serve video ads. VAST uses XML Schema as a markup language and VAST Tags are the bits of code used in this language.
  • Real-time bidding (oRTB) is the most commonly used protocol that automates inventory buying and selling within different programmatic auction types. RTB also offers a lot of capabilities including support of VAST types of inventory.

Step beyond the limitations of connection types

Now, let’s see how these standards can work for you. In the latest update, we’ve simplified it for our customers and made sure that those different connections “understand” each other. For those looking to optimize their ad delivery, understanding prebid server to server integration can be a game-changer in the programmatic advertising landscape. No need to whitelist every endpoint on the platform to create a VAST to RTB or VAST to VAST connections – media buying and selling are practically universal. 

You can trade not only VAST to VAST or RTB to RTB but also in a VAST to RTB, RTB to VAST, and VAST to all ways. Leveraging the capabilities of the prebid server can significantly enhance real-time bidding processes, ensuring optimal ad performance.

What else about the server to server integration? After doing several tests and investigations our team has pinpointed several important nuances. We found a difference in VAST Tags performance when trading with an Open RTB endpoint, or a VAST Tag only. So we have also added a new feature on SSP and DSP sides. By using this feature you can select how/which connection type you want your VAST tag to trade with: both VAST tags and RTB endpoints, only RTB endpoints, or only VAST tags.

Here’s how you can do it in the dashboard while adding supply or demand endpoints:

Here’s how to set it up and what it means:

  • VAST to ALL – when you select option VAST to ALL, this will allow your tag to trade with both Open RTB endpoints and VAST tags.
  • VAST to RTB – when you select option VAST to RTB, this will allow your tag to trade with Open RTB endpoints only.
  • VAST to VAST – when you select option VAST to VAST, this will allow your tag to trade with VAST tags only.

When generating a new VAST tag, fill in the standard fields and choose the VAST connection that suits your platform.

To sum up

In programmatic advertising B2B industry it is very important for the partners to maintain a consistent ad serving environment, that’s why making these standards compatible is an important step.
