Processes for determining predicted prices of social media actions from disparate social media types are disclosed. In one example process, campaign attribute data associated with an advertising campaign on a social media service may be received. The campaign attribute data and historical campaign attribute data associated with previously performed advertising campaigns may be used to generate a plurality of predicted prices for the social media action. A weighted sum of the plurality of predicted prices may be calculated to generate a final predicted price for the social media action. Predicted prices for other social media actions performed on other social media services may similarly be generated. Systems and non-transitory computer-readable storage media for performing these processes are also provided.
