Case Study: A Marketing Plan
I ran a logistic regression equation to understand how likely multi-category buyers are to purchase again in the next year ... after controlling for purchase frequency and AOV ... analyzing twelve-month buyers. Here's the results of the Logistic Regression equation ... nerdy stuff you can ignore (though I do want to show my work).
The variable "multicat" has an Exp(B) of 1.361 ... this means that any customer that historically purchased from more than one category was 36% more likely to buy again in the future AFTER controlling for purchase frequency and AOV.
Separately, I was able to demonstrate that "multiple" is important ... whether the number is two categories or seven categories is much less important.
In a prior analysis, we demonstrated that customers are responsive for a few months following a first purchase, then are dormant, then come back at months 11/12/13 and again at 23/24/25 following a first purchase.
A marketing plan becomes obvious.
- Separate email streams for first-time buyers within three months of a first purchase, attempting to generate a quick second order (preferably) within a second category.
- Personalize the merchandise in email campaigns for first-time buyers to increase the probability of a second purchase (preferably) within a second category.
- When a prospect visits via search, the goal is to convert the prospect to a first order and hopefully cross-shop the customer into a second item and/or second category.
- When a customer reaches recency = 11/12/13/23/24/25, we ramp-up messaging and frequency.
- Personalize the home page and/or landing pages to show customers what they "need" to see to maximize their future value.

Case Study: All Paths Lead to Apparel Tops
Yesterday I talked about Entertainment customers shifting dollars over time to Apparel Tops.
By the time the customer orders for the third time, 34% is in Apparel Tops, just 9% in Entertainment.
Does this happen to all categories? In this case, yeah, it happens to all categories.
Here are first order categories and migration through a third order.
Apparel Bottoms: 47% / 21% (Bottoms vs Tops) in first order, 16% / 35% in third order.
Fashion: 34% / 21% (Fashion vs Tops) in first order, 9% / 33% in third order.
Home: 47% / 19% to 18% / 32%.
Jewelry: 40% / 17% to 6% / 35%.
Workplace: 27% / 21% to 3% / 36%.
Outside: 51% / 12% to 17% / 27%.
Having Fun: 37% / 20% to 15% / 32%.
Seasonal: 34% / 19% to 7% / 31%.
Decorations: 31% / 20% to 9% / 32%.
Two interesting things happening, of course. First, customers on a first order do buy from multiple categories, with Apparel Tops being right there at the top. Second, as the customer evolves, the customer spends more and more money with Apparel Tops, less and less money with the category of a first purchase.
As a marketer, tell me how you plan on using this information to make different decisions? If the answer is "I'm not changing anything", that means something.
Tomorrow, we'll explore an email exchange discussing "doing something different" given we have knowledge of customer behavior.

Case Study: Entry Points Into A Brand And Subsequent Migration

Case Study: Off-Season Purchases
We've learned that "Beans: The Internet's Only Variety Store" is heavily skewed to the November/December timeframe.
I've learned across nearly twenty years of consulting project that it's not healthy for a business to skew so heavily to Christmas. You want to offer products that customers purchase all-year. If there's a reason that subscription-centric brands are coveted by investors, there's the opposite reason that Nov/Dec businesses aren't coveted.
When I see a skewed business, I run a regression model to test the dollar contribution of Oct/Nov/Dec orders vs. orders generated during the rest of the year. For twelve-month buyers, spanning four years of purchase history and one year of "prediction", here's the simple regression equation.
- 1.257 + 0.079*($ Spent in Oct/Nov/Dec) + 0.095*($ Spent Jan-Sep).

Case Study: Simple Forecasts
- 9.4% from last year's Apparel Tops AND Other Category buyers.
- 6.4% from last year's Apparel Tops only customers.
- 4.7% from last year's Other Category buyers.
- 79.5% from New/Reactivated buyers this year.
- Category Yes, Other Yes = $5.98 in the next year.
- Category Yes, Other No = $4.58 in the next year.
- Category No, Other Yes = $1.44 in the next year.

Case Study: When The Crabby Merchant Is Right ... And Horribly Wrong At The Same Time
In the email dialogue shared yesterday, the Chief Merchandising Officer suggested that her customers had long repurchase cycles, therefore, it's not fair to measure future value across only twelve months.
For "Beans: The Internet's Only Variety Store", she is both correct and horribly wrong at the same time.
Her customers have long repurchase cycles. I use my Life Table Methodology to measure repurchase activity/cycles. Here is what the data looks like.
The green table shows incremental repurchase probabilities by month, as well as cumulative repurchase probabilities by month, for 1x buyers, 2x buyers, 3x buyers, and 4x buyers. The graph next to the green table maps out incremental repurchase probabilities for first time (1x) buyers. Look at that stupid-high spike at month = 12. What do you think that is?
- It is customers coming back and repurchasing at high rates exactly one year following a first purchase.
- New customers spend maybe $11 in year one, $7 in year two, and $4 in year three. In total, that's $22 of future demand ... it's nothing.
