# 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. *** ## Types of Segmentation Filters * Based on `WHAT` activity they have performed in the past * Based on `WHEN` they performed a certain activity * Based on `CHARACTERISTICS` of the activity they performed * Based on `CHARACTERISTICS` of the customer's overall purchase history *** ## Limitations * Currently, only historical data from Shopify brands can be imported *Let's understand how to use the above filters to create segments!* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
