Segmentation
customer segmentationSegmentation means dividing a market or customer base into groups that differ in needs, behaviour or value. After the split, each group can get its own messages, channels and investment instead of everyone hearing the same thing.
Good to know
Segmentation’s value comes from differences: if the groups do not lead to different actions, the split is an academic exercise. A working segment is identifiable (you know who belongs), reachable (found in channels) and valuable enough to serve separately. Behaviour and need-based splits predict buying better than demographics alone.
Segmentation ties into choices: it leads to prioritising target audiences and giving each its own treatment. In practice the most effective start is your own customer data: your best customers reveal which segment produces, and marketing is aimed at more of their kind.
IN PRACTICE
The most common segmentation bases
Need and use case
Why people buy and for what: the same product solves different problems for different groups. The strongest basis for differentiating messages.
Value and behaviour
Purchase frequency, order size and lifetime value split customers into investment classes: who gets personal care, who automation.
Firmographics and demographics
Industry, size, location and role make a segment reachable in channels. Necessary but insufficient alone.
PITFALLS
Two segmentation mistakes
Segments without consequences
If every segment gets the same message and budget, the split is decoration. Segmentation’s output is different doing.
Too many groups
Ten segments exceed most teams’ capacity to serve. Three well-served groups beat ten nominal ones.
FREQUENTLY ASKED
Frequently asked questions
What is the difference between a segment and a target audience?+
Segmentation splits the whole market into parts; the target audience is the choice of which parts to pursue. First the split, then the choice and priorities.
How many segments is the right number?+
For most, 2–4 actively served. Every segment needs its own messages and content, so the count is sized to capacity.
What data is segmentation built on?+
Your own customer data: purchase history, relationship value and sales’ observations. Surveys and interviews deepen the understanding of needs.
How is segmentation taken into email?+
Lists are split by purchase history and interest, and messages differentiated: different content for new, active and fading. Open and click rates typically improve at once.
How often is segmentation refreshed?+
A light check yearly: do the segments buy as expected, have new groups emerged. In a market shift, more often.
