By identifying associations between products, retailers can strategically place related items near each other or offer personalized recommendations to increase sales and customer satisfaction. It helps improve inventory management, optimize product placement, and design effective marketing campaigns.
It also helps identify popular product bundles, improve supply chain management, and make informed decisions on product assortment and stock replenishment. Ultimately, market basket analysis helps businesses maximize revenue and customer loyalty by understanding and catering to customer preferences.
Types
Let us have a look at commonly used types:
- Association Rule Mining: This type identifies associations or relationships between items in a transactional dataset. It involves extracting frequent item sets and generating association rules that capture the dependencies between items. These rules can be used to recommend related products or optimize product placement.
- Sequence Analysis: This type analyzes the sequential order of items in customers' purchase histories. It aims to uncover patterns in the temporal sequence of purchases, such as identifying frequently occurring sequences or predicting the next item a customer is likely to purchase. This technique is particularly useful for understanding customer behavior over time and for personalized recommendations.
- Market Basket Optimization: This type goes beyond identifying associations between products and optimizing product recommendations and pricing strategies. It uses mathematical optimization models and algorithms to determine the most effective product bundles, pricing schemes, or promotional offers to maximize sales and profitability.
