Part 4: Cross-Category Correlation Model
In this fourth installment, we delve into the Cross-Category Correlation Model. This model uses
invoice-level transaction data to reveal how likely one product category is to be purchased
alongside another. By understanding these correlations, businesses can make informed
decisions that enhance marketing, sales, and customer satisfaction.
What is the Cross-Category Correlation Model?
The Cross-Category Correlation Model quantifies the relationships between different product
categories. It identifies which products are frequently purchased together and which are not,
providing valuable insights for strategic decision-making. Here are the key components of this
model:
1. Quantifying Correlations: The model uses statistical analysis to measure the likelihood
that products from different categories will be bought together.
2. Ranking Correlations: It ranks product or category correlations, highlighting the
strongest relationships.
3. Business Applications: The insights from these correlations can drive various business
decisions, from marketing to product placement.
Practical Application
To illustrate how the Cross-Category Correlation Model works, let’s look at an example.
In this example, the analysis shows that customers who purchase products in the Hard Floor
Care category are highly likely to also buy janitorial supplies and skin care, but their purchase of
gloves is significantly down.
We can apply this same analysis across multiple categories to give you a clearer picture of how
your products are correlated – positively or negatively. For example:
Key Insights from the Model
1. Highly Correlated Products: The analysis reveals that gloves, can liners, and skin care
products are frequently bought together with Warewash items. This insight can be used
to create targeted marketing campaigns.
2. Moderately Correlated Products: Cleaners & Degreasers are often purchased with can
liners, skin care, and janitorial supplies. Knowing this can help in designing product
bundles or special promotions.
3. Low Correlation Products: Identifying products with low correlation helps avoid
unnecessary bundling and ensures that marketing efforts are focused on high-impact
areas.
Strategic Benefits of the Cross-Category Correlation Model
Leveraging the information from the Cross-Category Correlation Model can help businesses
develop targeted marketing strategies based on actual purchase behavior of their customers,
developing strategic product bundles and promotions that will resonate with end-users and
move the needle.
1. Targeted Marketing: Develop targeted marketing campaigns that focus on customers
who are likely to purchase correlated products, increasing conversion rates. Use
correlation data to design marketing campaigns that promote products frequently bought
together, increasing the likelihood of multiple purchases.
2. Prompted Purchases: Bundle highly correlated products together in promotions,
creating value for customers and boosting sales. Encourage customers to buy correlated
products through suggestions during the shopping process, such as “You might also like”
sections on eCommerce platforms.
3. eCommerce Checkout Recommendations: Enhance the customer shopping
experience by recommending correlated products at checkout, driving additional sales.
By leveraging the insights provided by the Cross-Category Correlation Model, businesses can
make data-driven decisions that enhance their product strategies and improve overall
performance.
