The micro status is used for the evaluation of the short-term reach of goals and shows the cycle between (repeated) first contact and purchase.
"URM - Customer Micro Status" shows the visitor status, a user had had in the respective last visit.
A visitor is always assigned to exactly one status (the one with the highest priority). The assignment is done over all visits.
As soon as a purchase is made, the assignment to a new micro status starts with the next visit.
