# Segments

***

## Overview

A Segment, in theory, is a group of customers who share some common characteristics. 

Segmentation is widely used in the field of marketing to target the right audience for a marketing campaign. For example, cross-selling a hair conditioner to a set of customers who have purchased shampoo in the past. Or launching a new dry skin-related product to those who have purchased a product for the same concern in the past.

LimeChat's `Segments` tool helps you build such segments using which you can broadcast to the relevant audience or download the list of such customers to perform any other action.

* Based on `CHARACTERISTICS` of the customer's overall purchase history
