The Digital Video Ad Serving Template (VAST)

The digital video ad serving template (VAST) provides a standardized method for communicating the status of a video ad back to the ad servers in the case where the ad is served from a dynamically selected ad server. It is specifically designed for on-demand video player where the ad response is parsed prior to play.

VAST is applicable to Linear Video Ads (such as "pre-rolls"), Non-linear Video Ads (such as "overlays") and Companion ads as defined in the IAB Digital Video Ad Format Guidelines.

History

Due to both strong industry adoption and an evolving marketplace, VAST has continued to be updated in order to stay relevant.

The initial version of VAST was released in September 2008.

VAST 2.0

Released in November 2009, this formalized support for multiple creatives, linear and non-linear ads, and companion ads.

VAST 3.0

The upcoming version of VAST aims to include extensive industry feedback.

Compliance Program

The IAB allows members who have self attested to compliance with the VAST guidelines to obtain and post a VAST Compliance seal.
