To build a strategy and segment your customers, follow these steps: 

  1. Define your goals. This will help you prioritize when setting up customer segments.

Customer segmentation tools you will need 

When building out your strategy, decide early on what tools you will use. Some examples of tools needed for segmenting customers are Google Analytics, Hubspot, psychographic data, and visitor cross-shopping analytics.

Google Analytics is the go-to option for many businesses to track customer visits to an online store and better understand their behavior. 

To begin segmenting customers, go to the reports tab and select the segment field. From there, you can create a new segment. Segments can also be added to reports. 

While Google Analytics is a useful tool for marketing and digital customer segmentation, it does miss some key information you will need for segmentation. Consider it the start of the process rather than a pillar. 

2. Hubspot 

Hubspot is a CRM platform perfect for sales and marketing teams. When creating segments, Hubspot lets you choose your criteria from engagement to demographics. 

From there, you can analyze the different segments and even create separate landing pages depending on the customer type.

When designing a marketing campaign, store layout, or developing a new product, psychographic data is an important step in the process of customer segmentation. It can also help you build customer personas. 

This data gives you an anonymized view of income and education levels, allowing you to better optimize your campaigns to suit their interests.
