This document discusses Unruly ShareRankTM, a proprietary algorithm developed by Unruly Media to predict the shareability and virality of video content. The algorithm was created based on over 300 billion video streams analyzed to identify key metrics that influence how likely content is to be shared. These metrics include basic emotions, cognitive responses, social motivations and psychological factors. Unruly ShareRankTM can then be used to optimize content strategies and maximize sharing of new videos.
