VAST Macros for Video Ad Monetizations Guide

Ad servers, measurement partners, and buyers seek access to additional data from publishers to enhance their understanding of the environments where ads are served. In 2018, the IAB Tech Lab introduced a standardized set of VAST player macros to promote transparency across various VAST environments. These macros, known as VAST Macros, empower publishers’ media players to convey supplementary data points within ad requests, thereby facilitating Video Ad Monetization.

These macros facilitate the transmission of information such as user agents and app details to the serving VAST ads. They are universally compatible with VAST 2.0 and later environments. A VAST ad tag URL serves as the conduit for players to retrieve video and audio ads. AST (Video Ad Serving Template), a specification by the IAB, structures ad tags for efficient delivery.

Ad servers, including third-party servers such as Google Ad Manager (GAM), SpringServe, Aniview, SpotX, Magnite, PubMatic, Publica, and other video ad servers, leverage ad tag variables to optimize fill rates and ad targeting. These servers utilize ad tag variables within the ad tag URL to enhance the delivery of video and audio ads to target audiences effectively.
