Daily active users (DAU) is one of the ways used for measuring success of an internet product, e.g., online social games. DAU measures "stickiness" of an online product – how many unique users visit the site daily? Usually the only requirement for a user to be considered "active" is that they somehow view or engage with the product. Examples of this type of usage would range from visiting the splash page of a game or commenting on a post by the game's Facebook page, to actually playing the game itself. The monthly aggregate of DAU is monthly active users (MAU).
