Methods and apparatus for predicting network activity are disclosed. In response to a requested value of an independent variable describing a suspected determinant of network activity for a network content provider, a set of predicted values of a dependent variable is displayed. The set of predicted values of the dependent variable is predicted based on a relationship between the independent variable and the dependent variable. The dependent variable reflects an aspect of the network activity for the network content provider. The relationship is derived from a plurality of metric values, and the plurality of metric values includes metric values describing the network activity for the network content provider. A plurality of independent variables is set to the requested value of the independent variable. A plurality of values of the dependent variable is displayed based on a plurality of respective relationships between the plurality of independent variables and the dependent variable.
