Behavior Offset: apply a date offset to your in-line cohorts

Available for all Scholarship, Growth, and Enterprise customers

Behavior Offset helps you track how and when a user transitioned from one cohort into another cohort, by defining the user’s state in a previous time period. This is useful if you want a deeper understanding of how your user base is changing over time. You can track when an active user became a power user, or when a novice user became an engaged user, and then try to inspire that behavior in a larger user base with strategic product investments.

In the chart below, the user definition for the previous period is users who performed Play Song or Video >= 1 time any time in each day offset by 30 days. The user definition for the current period is users who performed Purchase Song or Video >= 1 time any time in each day.

The highlighted data point tells you that on Mon, Mar 30, 23 128 users performed Play Song or Video 30 days prior to performing Purchase Song or Video. For more information on Behavior Offset, check out our .

Apply a rolling window to your in-line cohorts

You can also add a rolling window to your offset in-line cohorts in order to increase the interval of the previous time period.

In the chart below, the user definition for the previous period is users who performed Play Song or Video >= 1 time any time in each day offset by 1 day with a rolling window of 30 days. The user definition for the current period is set as users who performed Purchase Song or Video >= 1 time any time in each day.

The data point in this chart tells you that on Mon, Mar 30, 94 262 users performed Play Song or Video any time during the 30 days prior to performing Purchase Song or Video (i.e., users who purchased a song or video within 30 days of playing a song or video.)
