It's no longer a secret that personalization in eCommerce works. In fact, up to 65% of your customers expect it—not only in your store but as part of your marketing efforts too. Personalized marketing, including customer personalization and customer or audience segmentation, can significantly influence buyer behavior and increase sales and customer loyalty. While they may seem similar, customer personalization and segmentation are different in their approach and business outcomes.

What Is Customer Personalization?

Customer personalization is the process of using data to tailor specific services and products to individual customers to enhance their shopping experience.

Businesses use different customer data points like browsing history, purchase behavior, and geological location to understand each customer. This approach includes customized messages, product recommendations, product bundles, and customer services.

By implementing personalization, businesses can enhance customer satisfaction and loyalty as customers feel more valued by the brand. The personalization experience can also lead to increased sales and revenue, as customers are more likely to shop at a store they feel more connected with.

What Is Customer Segmentation?

Customer segmentation is the practice of dividing a business's target audience into groups based on shared features or behaviors.

Customer segmentation may be classified into three types:

  • Demographic segmentation: based on age, gender, income, and occupation
  • Psychographic segmentation: based on personality, values, and interests
  • Behavioral segmentation: based on browsing and purchase history, average order value, and session frequency

By creating customer segments, stores can better address each group's specific needs and appeal to their preferences based on their shared traits.

Key Differences Between Customer Personalization and Segmentation

Customer Personalization


  • Tailors shopping experiences to the individual
  • Based on each customer's traits, preferences, & behavior
  • Centers around the customer's needs
  • Usually happens after segmentation has been established
  • Requires advanced technology like AI & machine learning

Customer Segmentation

  • Based on characteristics, preferences, & behaviors shared by a group of customers
  • Centers around the marketer's needs
  • Comes before personalization
  • Uses more basic CRM software & marketing tools
