The Video Ad Serving Template (VAST) provides a standard XML-based ad response for in-stream video for on-demand video players where the ad response is parsed prior to play.
Details on VAST can be found on the Interactive Advertising Bureau VAST guideline.
This page verifies VAST 2.0 compliance in two ways:
- Provides sample VAST tags for you to test in your player to confirm VAST compliance.
- Verifies your VAST ad response is compliant by testing it within our Media Player.
1. Below are sample VAST tags for you to test in your player to confirm VAST compliance
To check whether your video player is VAST compliant, use the ad tags below. These are generated to verify that your player displays the ads correctly and calls all the appropriate tracking URLs.

2. Below you can verify whether your VAST ad response is compliant by testing it within our Media Player
To check whether your video ad response is VAST compliant, paste your VAST ad tag or VAST ad response into the text field below and then click the "Display Ad" button. Our video player will verify and display the VAST ad response, and will also ping the tracking URLs.
