VAST (Video Ad-Serving Template) is an XML-based standard that is used by digital video publishers to serve and manage video ads on their websites, apps, or platforms. VAST was developed by the Interactive Advertising Bureau (IAB) to address the challenges and limitations of video advertising, such as the lack of compatibility, complexity, or scalability. VAST provides a consistent, interoperable, and scalable framework for video ads, and it enables publishers, advertisers, and ad networks to exchange and track information, such as ad creative, duration, tracking, or companions. VAST also supports different video ad formats, such as linear, non-linear, in-stream, or out-stream, and it allows for the integration of video ad content with video player technology. VAST is widely adopted and supported by the industry, and it is an important part of the programmatic ecosystem for video advertising.
