This document discusses using behavioral data from website visitation to target survey respondents more precisely. It describes how a survey panel can be segmented based on how frequently members visit over 150 categories of websites. Combining survey profile data with behavioral data allows for more targeted surveying of customers and prospects. Several case studies are presented that demonstrate how behavioral targeting was used to identify auto intenders, understand competitive shoppers, and gauge intent to purchase cruises. The key benefits are gaining deeper audience insights, informing marketing efforts, and validating audiences.
