Types of Customer Segmentation: Micro-Audiences

  • Spend Groups (Average Order Value, Total Spend, etc)
  • Geographic Differences
  • Use Cases or Solutions
  • High Profit (Margin) customers

FAQ

What are the main types of customer segmentation?

The main types include demographic segmentation (age, gender, income), geographic segmentation (location-based), behavioral segmentation (purchase history, engagement patterns), psychographic segmentation (values, interests, lifestyle), and micro-segmentation based on specific attributes like product categories, spend groups, or use cases. Modern CDP approaches often focus on micro-audiences for more targeted and effective personalization.

How does customer segmentation improve marketing ROI?

Customer segmentation improves marketing ROI by allowing brands to deliver targeted experiences and messages to specific groups rather than broad audiences, reducing wasted ad spend and increasing conversion rates. It helps identify high-value customer segments for priority targeting, enables personalized next-best action recommendations, and allows marketers to optimize campaigns based on behavioral and transactional trends within each segment.

What is the difference between customer segmentation and personalization?

Customer segmentation is the process of grouping customers into audiences based on shared characteristics, while personalization uses those segments (and individual data) to deliver customized experiences to each customer. Segmentation is the foundational step that organizes customers, and personalization is the execution that tailors content, offers, and messaging to individuals or groups based on their segment membership and unique behaviors.
