For all of those who don’t know yet:
Youtube has upgraded some of their key functions. One interesting new feature is the video owner option called ‘insights’.
You cannot only see where the viewers are coming from and whether they found the ad in a player, via youtube/google search or via related videos…
But also see what part of the video they really liked! Something we should certainly share with our clients! It only works if the video has been online for a bit and gets enough views, though. (data goes back to 2007!).
