Market & Targeting

# Customer segmentation

In short

Customer segmentation is the practice of dividing customers and prospects into groups based on shared characteristics, such as industry, size, needs, or behavior. Each group is then treated with its own approach.

In B2B, the goal is to focus on the segments that buy fastest, stay longest, and grow most, and to stop spreading effort evenly across everyone.

## Ways to segment customers

* **Firmographic:** Industry, company size, revenue, and region.
* **Behavioral:** Product usage, purchase history, and engagement with your content.
* **Needs-based:** The problem they hire you to solve or the outcome they want.
* **Value-based:** Revenue, margin, and lifetime value, often used to set account tiers.
* **Lifecycle:** Prospect, new customer, expanding customer, or at-risk customer.

## How to segment step by step

### 1. Start from existing customers

Export customers with retention, expansion, and sales cycle data. Look for groups that behave differently from one another.

### 2. Pick one or two dimensions

Too many dimensions create segments too small to act on. Say you find that mid-sized software firms close in half the time of large manufacturers. Industry and size are then your first cut.

### 3. Test that each segment is usable

A segment must be big enough to matter, identifiable in your data, and different enough to need its own message or motion.

### 4. Act on it

Give each segment its own messaging, offer, and owner. A segment with no changed action is only a label.

## Customer segmentation vs. market segmentation

Customer segmentation groups people or companies you already sell to, using data you hold on them. Market segmentation groups the whole potential market, including companies you have never contacted. Teams often use customer insights to decide which market segments to enter.

## Common mistakes

* Segmenting by what is easy to export instead of what predicts buying behavior.
* Creating so many segments that no team can run a distinct play for each.
* Using stale data, so accounts sit in the wrong group after they change size or industry.
* Building segments that sales and marketing define differently.

## Customer segmentation FAQs

**What is customer segmentation in B2B?**

B2B customer segmentation is dividing customers and prospects into groups that share traits such as industry, company size, needs, or behavior. Each group then gets tailored targeting, messaging, pricing, or sales approach based on how it buys.

**What are examples of customer segmentation?**

Examples include grouping accounts by industry, by employee count, by the problem they want solved, by product usage level, or by lifetime value. A software firm might separate fast-closing mid-sized tech companies from slower enterprise accounts.

**How many customer segments should you have?**

Most teams do best with a small number, often three to six, that they can actually run different plays for. If a segment does not change your message, offer, or owner, merge it into another one.

**What is the difference between customer segmentation and market segmentation?**

Customer segmentation groups the people or companies you already serve using your own data. Market segmentation groups the entire potential market, including companies you have not reached, to decide where to focus.
