Leer Behavioral Segmentation with Python | Rule-Based Customer Segmentation

Behavioral segmentation is a powerful technique for understanding how customers interact with your business based on their actions, rather than just their characteristics. By analyzing behavioral patterns—such as purchase frequency, average order value, and recency of transactions—you can group customers according to how they engage with your product or service. This approach enables more precise personalization and targeting, as you can tailor communications, offers, and experiences to match the specific habits and preferences of each behavioral segment. For example, frequent buyers may respond well to loyalty programs, while customers who haven't purchased recently might benefit from re-engagement campaigns. Behavioral segmentation moves beyond static attributes to capture the dynamic relationship between your business and its customers.

Behavioral segments are fundamentally different from demographic or rule-based segments. While demographic segmentation organizes customers by static attributes such as age, gender, or location, and rule-based segmentation applies predefined business rules to group customers, behavioral segmentation focuses on how customers actually behave. This means you are segmenting based on patterns like how often someone buys, how much they spend, or how recently they have interacted with your business. As a result, behavioral segments are dynamic and can change as customer actions change, making them especially valuable for real-time targeting and personalized engagement strategies.
