What Are VAST Tags?
Definition and Purpose of VAST Tags
VAST tags, or Video Ad Serving Template tags, are essential tools for digital publishers. They serve as a standardized framework that facilitates the delivery of video ads across various platforms. By using XML schema, VAST tags communicate crucial metadata about video advertisements, such as ad type, duration, and tracking information. This ensures a seamless integration of ads into video content, regardless of the publisher’s ad server or network.
How VAST Tags Function
The Process of VAST Tag Operation
VAST tags operate through a straightforward process involving three key steps:
- VAST Request: The video player sends a request to the ad server to retrieve the appropriate video ad.
- VAST Inline Response: The ad server responds with an inline or wrapper response containing the necessary ad details.
- Ad Execution: Finally, the media player executes the ad based on the received VAST tag information.
This process allows for efficient communication between the ad server and video player, ensuring that ads are displayed correctly.

Key Components of a VAST Tag
A typical VAST tag consists of several critical elements:
- Creative: Defines the advertisement itself.
- Tracking: Includes tracking events to monitor ad performance.
- MediaFile: Specifies the media file associated with the ad.
These components work together to ensure that ads are delivered accurately and effectively to viewers.
The Evolution of VAST Tags
Historical Context and Development
Since its inception in 2008, VAST has significantly evolved to address challenges faced by publishers in delivering video ads.
