A system and method to optimize storage of activities performed by a user over a network are further described, wherein activity information related to an activity performed by a user over a network is received. The activity information is further processed based on associated schema information to extract primary property information related to the user and containing an activity identification parameter related to the activity and secondary property information related to additional aspects of the activity. Finally, the primary property information and the secondary property information are transmitted to respective storage modules for subsequent storage. A method to retrieve optimized activity information is further described, wherein a request to retrieve user activity information is received from advertising servers. Schema information related to the user is further retrieved from a schema module. The user-specific primary property information and the secondary property information are further retrieved from the respective storage modules. The primary property information and the secondary property information are further processed and transmitted to the advertising servers in response to the received request.
