A method of and a system for ranking users by activity level and achievements within the services exchange medium (SEM) enables better searching for a service provider. An activity score for each service provider is periodically determined. The activity score is based on a point scheme. The point scheme, which is tunable, drives particular behaviors within the SEM by rewarding points for a first set of activities and taking away points for a second set of activities. Upon receiving a query, a total score, which is dependent at least in part on the activity score, is calculated. The results list is sorted based on the total score.
