In one embodiment, a method includes determining by a computing device a set of videos that a user may watch. For each video, a coefficient value is determined for each of one or more coefficient factors. At least one of the coefficient factors has a value that would be coincident with the user watching the video. A video coefficient for each video is calculated based on the coefficient values of its coefficient factors, and the videos are ranked based on their video coefficients. The rankings are then provided for presentation to the user.
