Video Web Ads Guide

What are Video Web Ads

There are two types of Video Web Ads: in-stream and out-stream. 

  • In-stream video ads play within video-based content, such as Dailymotion. Ads pop-up pre-roll, mid-roll, and post-roll. 
  • Out-stream video ads appear within non-video-based editorial content. Outstream video ads appear outside of any streaming content, similar to standard display ads.
