Understand the difference between behavior offset and behavioral cohorts
Determine when using a behavior offset is appropriate, and when it isn't
With Amplitude's behavioral cohorts, you can create groups of users who share a pattern of behavior. The behavior offset feature gives you the power to further segment these users based on behaviors they've displayed in two distinct time periods.
Common use cases for behavior offsets include:
In each of these use cases, there are two cohorts in play, separated from each other by the passage of time. In the second example, they are:
Behavior offsets make it easy to segment the users who appear in both of these cohorts.
This feature is available to users on Growth and Enterprise plans only.
Before getting started, you should read up on behavioral cohorts and rolling windows until you're comfortable with both concepts.
This section follows the first example in the bulleted list above: segmenting for users who made at least one purchase in the current period, but also made two or more purchases in the last 90 days.
To add this behavior offset, follow these steps:
Complete Purchase
.In the rolling over field, enter the number of days you want to allow for the current period event to occur. In this example scenario, that value is 90.
You can change the default durations from per day to weekly, hourly, monthly, or quarterly by changing the setting in the Metrics Module's date picker.
Also, when using a during cohort (as opposed to in each; see this article on in-line cohorts in Amplitude for a more detailed explanation), the offset function allows you to create daily offsets, regardless of the interval you set in the date picker.
From the same menu as in step 4, click Add offset. In the offset field, enter the number of days after the occurrence of the previous period event that you want to wait before the rolling window (see step 4 above) begins.
In this example, the day of the previous period event doesn't belong in the rolling window, so enter 1. If you want to include that day in your analysis, don't include an offset.
Click + Performed again. From the and who performed drop-down, select the current period event. Continuing with the example, this is Complete Purchase
.
Your in-line cohort—in which you’re segmenting for users who completed one or more purchases in the current period, and completed two or more purchases in the previous period (90 days, in this case)—should now look like this:
By applying the rolling window and offset to the previous period event, you've essentially shifted this cohort to a time in the past. This process offsets only the in-line cohort, and not the event selected in the Event Module.
In-line offset for in each cohorts is available on Event Segmentation charts. In-line offset for during cohorts is available on all chart types except Compass. When using a during cohort, you must define your date range in days.
