Weird Categories

Every one of you managed Weird Categories.

In the data I'm analyzing, a customer could buy from a category last year or not ... then buy other merchandise (or not). This creates three twelve-month buyer segments. I segment based on behavior 13-24 months ago, then measure rebuy rates in the past year.

Here's what a normal category looks like:

• Buy From Category 2 and Buy From Anything Else = 15.2% Category Rebuy Rate.
• Buy From Category 2 no Purchase From Anything Else = 8.1% Category Rebuy Rate.
• No Order From Category 2 and Buy From Anything Else = 2.4% Category Rebuy Rate.

Normal categories benefit from purchases in other categories, but benefit most from a purchase within the category. Duh!

Here's what a weird category looks like.

• Buy From Category 6 and Buy From Anything Else = 12.4% Category Rebuy Rate.
• Buy From Category 6 no Purchase From Anything Else = 16.2% Category Rebuy Rate.
• No Order From Category 6 and Buy From Anything Else = 0.8% Category Rebuy Rate.

Very weird. The customer is less likely to repurchase from the category if the customer buys something else in the past year from other categories ... and ... the customer has virtually no chance of buying from Category 6 if the customer only bought from other categories last year.

If you are responsible for Category 6, you don't send batch-and-blast emails to customers who haven't bought from Category 6 very often because those customers just don't want to buy from this Weird Category! There are seasons that likely cause customers to consider Category 6, that's when you try to cross the customer over into this category.
