A server-based system is provided for analyzing and valuating social media campaign performance. The system collects online traffic data from member users of a social media channel, and tracks engagement activity with respect to a social media campaign operating on the channel according to parameters defined with respect to specific activities including: user interactions with media content of the campaign; user transactions as non-commercial data exchanges or commercial purchases conducted via the campaign; and user sharing of the campaign with other member users of the social media channel. The system establishes baseline performance thresholds and aggregates the tracked engagement activity with respect to the defined parameters. A graphical user interface is generated to display client feedback related to a comparison of the aggregated engagement activity with the established baseline performance thresholds for each of the defined parameters.
