An online system maintains information describing interactions by its users with various applications. To allow evaluation of an application against other applications, the online system identifies additional applications having a threshold measure of similarity to the application and with which at least at threshold number of users interacted during a time interval. Based on a number of users who interacted with various additional applications and amounts of revenue obtained by additional applications, the online system selects a group of additional applications. The online system selects additional applications from the group based on scores for the additional applications determined from user interaction and revenue obtained by the additional applications and provides information about the additional applications selected from the group to an entity associated with the application.
