Identify users with similar behaviors

In Amplitude, a cohort is a group of users who share a trait or set of traits. There are two different types of cohorts: predictive cohorts and behavioral cohorts.

Behavioral cohort restrictions

• Organizations on the Plus plan have a limit of five behavioral cohorts.

Behavioral cohorts are defined by user actions taken within a specific time period. They group users based on the events they triggered in your product. After you create a cohort, you can add the cohort as a segment in many Amplitude charts.

Examples of behavioral cohorts include:

• Users who watch three consecutive episodes of a TV show in the first day after signing up for a video streaming service
• Users who enable push notifications during onboarding
• Android users who abandoned their carts on an e-commerce site in the last month

Behavioral data reveals how engagement with your product affects retention, conversion, revenue, and other business outcomes.

Cohorts are useful across the Amplitude platform. To segment your data by cohorts, select Cohort in the Segmentation Module, and then choose the cohort from the dropdown list.

For any chart or query that segments on a cohort, the segmented cohort automatically recomputes whenever the chart generates. You can manually recompute the cohort at any time by clicking the refresh icon.

If you have the Accounts add-on, you can apply a group-level cohort instead of a cohort of users. When you select a specific group type, only the cohorts it contains appear in the drop-down list on the right side of the equals sign:

You can also create a chart using the cohort directly from the Cohort page.

Before you use a cohort in a chart, define a new cohort.
