Different products will create different customer behavior.
Some products will produce customers that order more frequently.
Some products will produce customers that place larger orders.
Some products will produce customers that defect and go to competitors.
A large part of product analysis is finding out how each product influences customers. Then you can promote the products that best match your goals.
The Product Reorders and Nth Product Analysis in Repeat Customer Insights will do these sorts of analyses for you to see the long-term customer behavior metrics from each product.
Directive: Promote the products that create the customer behavior you want.
