What is a Video Ad Serving Template (VAST) Tag?

A VAST tag is an XML code snippet that acts as the communication bridge between a video ad server and a video player within a mobile app. It essentially instructs the video player how to fetch, display, and track video ads. The VAST tag specifies details such as:

  • The ad creative: The URL of the video ad file (usually an MP4) to be displayed.
  • Impression tracking: Code snippets that notify the ad server whenever the ad is displayed to a user.
  • Click tracking: Code that tracks user clicks on the ad, allowing for measurement of click-through rates (CTRs).
  • Companion banners: Optional elements specifying companion banner ads to be displayed alongside the video ad.
