Where you acquired a customer from can have a dramatic influence on their behavior, both in the initial purchase and all later purchases.
These acquisition channels lay down their expectations which can persist for a long time.
Anytime you begin to optimize any metric, take a look at it through the different channels (Repeat Customer Insights will compare them for you automatically). Look for higher than normal, lower, and outlier values.
