Description: Browsing and buying behavior of a panel of 100,000 internet users in the United States.

The comScore Web Behavior Database captures detailed browsing and buying behavior by 100,000 Internet users across the United States at the domain level. The panel is based on a random sample from a cross-section of more than 2 million global Internet users who have given comScore explicit permission to confidentially capture their Web-wide activity.

The unique panelist identifier is Machine ID and there are cases where multiple configured machines exist within a household, but all demographic information is based upon the associated household. All sessions are aggregated by machine in the household, so that individual breakdowns are not available and a particular individual could use more than one machine. The items below are associated with each machine-household.

Note: Access through WRDS contains annual data for 2013 only and summary historical data for 2004-2008. The data are the raw data from the sample and are not projections for the total population. See WRDS for additional details.
