Exemplary methods, apparatuses, and systems generate a first candidate list of users that meet a first set one or more characteristics and a second candidate list of users that meet a second set one or more characteristics. When a user appears in both of the first and second candidate lists, the user is selected to receive only the first survey or only the second survey based upon a first priority value for the first survey and a second priority value for the second survey.

Survey targeting

An embodiment of a system and method of surveying users on a social networking system is described which limits the frequency in which any one user is surveyed. Users are assigned into a multi-layered survey pool based on a hash value derived from a user identification number for the online social network that is assigned to the user. Users are randomly offered the opportunity to take a survey, and the subject matter of the survey is at least partially determined by the layer from which the survey obtains its sample populace.
