After I clicked the embedded video, I got to the video’s homepage and noticed control panel for “owner” (notice: you can only see this if you are the author of the video – in other words: have uploaded the video in your youtube account).
There I saw the button “insight”:
I moved on and started checking what other stuff could be found behind the “Insight”. There was some information about the demographics (for one of my zombie game videos): 83% male, 17% female have been watching the video. Most of them are within 18 to 34 years, but there’s also quite many 13-17 years old (20+%) and also 35 to 54 years old (25%).
There was also other information such as discovery (which sounds how people found the video: embedded on a site, external links, through youtube’s “relevant videos” link etc.), popularity, hot spots and views. You can also see from which countries people have watched the video.
I found this to be pretty nice addition for tracking information about who is watching your game videos.
