What is VAST Ads
VAST (Video Ad Serving Template) is a widely adopted XML-based standard used to deliver video ads across players, devices, and platforms. It defines how a video ad should load, track impressions, fire events, and interact with the player. VAST tags allow advertisers to run linear, non-linear, and companion video ads in environments like desktop, mobile apps, CTV, OTT, and streaming platforms. Using VAST ensures consistency, reliable tracking, and compatibility across the digital video advertising ecosystem.
