While YouTube Insight already provided detailed feedback about the performance of videos to their creators, a (seemingly) recent development has made this information now public and for all to see. Well, I could not find any other online medium reporting on this, so either this has been around since quite some time, or was not deemed newsworthy enough.
Each YouTube movie now features a detailed data visualization dashboard, which shows the number of views over time, including the exact occurrences when the movie was embedded at an external source. While competitor Vimeo has since long listed the number of views and 'likes' in bottom right corner, the YouTube version takes a more contextual approach.
In the usage statistics of great infographic movie "Growing Up", for example, one can clearly perceive the impact of different design blogs on the number of views, next to the effect on the movie's Ratings, Comments and Favorites, plus a breakdown on age and geographical location. This feature can be revealed by simply clicking next to the arrow icon near the number of views.
In other social media statistics developments, YouTube now also features a speed dashboard, which contrasts the performance of your online connection, while popular link shortener bit.ly has recently rolled out a sophisticated analytics dashboard as well.
