Systems and techniques are described for splitting user-lists. A described technique includes obtaining a master user-list, the master user-list including object identifiers that are respectively associated with web clients; obtaining a splitting factor that controls a splitting of the master user-list; creating a reduced user-list from the master user-list based on the splitting factor such that the reduced user-list maintains a statistical fidelity of the master user-list, the reduced user-list including fewer than all of the object identifiers included in the master user-list; and providing the reduced user-list. |
