In one embodiment, the system determines network performance metrics in a number of geographic areas within a communication network based on application data of end users. The system receives, from a client system, a query for geographic areas of interest specifying network performance criteria based on network performance metrics and corresponding thresholds. The system identifies geographic areas of interest matching the network performance criteria of the query. The system determines, for each geographic area of interest, network performance features based on network performance metrics derived from application data collected from the geographic areas of interest. The system generates optimization recommendations for one or more of the geographic areas of interest. The optimization recommendations are customized for the geographic areas of interest based on the performance features associated with the respective geographic areas of interest. The system sends, to the client system, instructions for presenting the optimization recommendations.
