Clickstream analysis methods and systems related to modifying an offline promotion for a consumer good

A system comprising:

• one or more processors;
• a memory bearing instructions that, when executed, cause the one or more processors to:
• identify demographic information about members of a target population;
• based at least in part on the demographic information, identify a group of participants in the target population;
• identify Uniform Resource Locators (URLs) in one or more clickstreams of the group of participants;
• decompose and hash each URL in the one or more clickstreams;
• calculate, based at least in part on the decomposed hashed URLs, a metric of cross-shopping behavior of the group of participants between different consumer goods;
• and
• transmit the metric through a communication facility to a remote machine for use in an offline process to determine where consumer goods should be presented in a retail store.
