VAST Definition
The Video Ad-Serving Template (VAST) is an industry-standard XML format that allows ad servers to deliver video ads to different video players across platforms. VAST ensures ads load correctly, track performance, and support formats like pre-roll or mid-roll ads.
How VAST Works
- Advertisers generate VAST-compliant ad tags from their ad server.
- Video players on websites or apps request ads via the VAST tag.
- The ad is served with instructions on tracking, creative type, and duration.
- Engagement and impression data is reported back to the ad server.
Example of VAST
A media site uses a VAST tag from Google Ad Manager to display a 15-second video pre-roll ad before streaming content.
Why VAST Matters in Advertising
- Ensures consistent video ad delivery across platforms
- Supports tracking for impressions, clicks, and viewability
- Reduces compatibility issues between ad servers and video players
- Essential for scalable, programmatic video advertising
