# Cohorts by first product: find the product that wins customers worth keeping

July 24, 2026 · Updated November 1, 2026

## Overview

Group your customers by the first product they bought and see which
one brings in people who keep spending. Lead your acquisition with
that product, not just the one that wins the first order.

## Which first product keeps customers

The
[Cohorts guide](https://help.tryordinary.com/features/cohort-retention)
explains each way to group customers and what each number means.

### Group customers by their first product

Alongside channel, country and U.S. state, group every customer by the first product they bought. Each product becomes its own cohort, side by side.

### Compare what each group spends over time

A product with a smaller first order can still bring in customers worth far more months later. Groups too new to measure show a dash, so you never compare a few weeks against a full window.

### See who comes back for a second order

Tell a one-and-done product apart from one that starts a habit.

Grouped by channel

## Which channel's customers pay you back

Grouped by channel, each row is a month of new customers. Each cell
shows how they're doing up to twelve months later, so you see which
channel's customers pay for themselves, and how fast.

### Acquisition cost earned back

How much of what you paid to acquire them they've already earned back: your CAC payback period, month by month.
