VAST Introduction

VAST (Video Ad Serving Template) is a specification defined and released by the Interactive Advertising Bureau (IAB). VAST sets a standard for communication requirements between Ad Servers and Video Players to present video ads, and it is declared using XML.

Note: The default standard served through ExoClick is v3, although VAST Wrappers might redirect to VAST using other versions of the standard.

In this section you will find visual examples of XMLs returned by our ads and detailed explanations of each element within these XMLs:

Our VAST tags correspond to In-Stream and In-video ad zones. For a simple explanation on how to add an In-Stream or In-Video ad zones to your website, please check our tutorials:
