Web Survey Bibliography
Kantar Media in partnership with Safecount produced a test of a passive, direct, and involuntary approach for the collection of visitation behavior focused primarily on health-related websites. The approach involved a single read of available cookie data. The results were matched back to survey data that include website visitation behavior collected via respondent recall. The results did not produce strong agreement between data collected passively versus recalled. There exists attrition of cookie-based usage history as that history moves farther into the past.
