Customer segmentation divides an audience into groups that share meaningful conditions. Purchase frequency and category interest often connect more directly to action than broad labels.
Change the purchase threshold in the demo and customer dots move in or out of the target group. Check whether each group would actually receive a different message, not only its size.
Overly narrow segments create tiny groups that are hard to operate. Decide what action differs between groups before adding another rule.
When to use
Use it when different customer groups call for different goals or messages.
