YouTube will provide more information about video viewers.

Authors uploading their videos to YouTube will be able to get more information about the people watching the video. The new program YouTube Insight will show videos per day, as well as provide information about the location of the audience. For those who work with YouTube on a commercial basis, the program will also show information about how many people watched the video to the middle and to the end.

It is assumed that the new program will help advertisers to receive statistics, which may be important for ad placement. For example, a studio that posts a trailer on YouTube can see in which countries it is most popular and, possibly, purchase television advertising aimed at users from this region. The program can also be useful for music groups that can plan their tour based on this information. YouTube Insight is also useful for those who post videos constantly: they can see which days of the week are the most visitors, and also calculate at what intervals it’s best to publish new videos.
