Patent ID: 7890451

Claim:
A method of estimating Internet traffic, the method comprising: taking a size and demographic composition of a target population; identifying a group of participants within a target population; determining demographic information for each member of the group of participants; receiving click-stream data at a host processing facility from the group of participants that connotes Internet activity of individual members of the group of participants, wherein the data are from a plurality of sources; producing, at the host processing facility, an estimate of a target population's Internet activity by scaling the data for each member of the group of participants to the relative size and demographic composition of the target population and the group of participants, wherein scaling comprises applying a weight to the clickstream data in view of the demographic information; and refining the estimate of the population's Internet activity by applying a domain-specific bias adjustment to the estimate, wherein applying the domain-specific bias adjustment to the estimate comprises applying a weight to a subset of the data from the group of participants, the subset of the data that connotes a specific domain.
