  • Sampling distinct groups of customers and prospects who have made Search-influenced category purchases both online and off
  • Collect offline purchase data related to online search activity, at a product and category level
  • By probing the level of influence of Search in each product category, calibrate the dollar impact on an individual respondent level and extrapolate dollar amounts back out to the category at large
  • Taken together, these metrics can connect offline behavior with online search activity, and calculate a potential dollar influence Search can have on each category.
  • Historical purchase data appended from customer transaction database gave additional insight into self-reported versus actual purchase data collected in the survey to extrapolate results to the customer universe at large.

Similarly in off-line transactions, those who search 10 or fewer times spend an average of $2,219 through retail locations, while those who search 31+ times spend an average of $3,839.
