Form of Online Video ad placement where the advertisement is played before the content Video plays. Check with the media planner as individual sites will need to be VAST compliant for eyereturn to ad serve pre-roll video. 

If they aren’t VAST compliant, eyereturn can still track impressions, clicks and video start, middle and end. But in this case videos should be produced to publisher specs and delivered directly to the sites.
