At a glance: Increase incremental lift by retargeting inactive users. Set inactivity windows by media source.

Inactivity period

Advertisers regain inactive users by retargeting them. These campaigns usually have a good conversion rate and generate significant ROAS. However, many retargeting campaigns underperform as they don't filter out active users. To increase the incremental lift of retargeting campaigns, implement minimum inactivity time to filter out active users.

By setting a minimum inactivity time, Advertisers don't attribute active users. For example, if the minimum inactivity limit is three days, then users active in the previous 0-3 days aren't attributed. Users inactive for four or more days are attributed. The inactivity period applied to both re-attribution and re-engagement scenarios. In the case of re-attribution, the last activity is the last session before performing the uninstall.

Inactivity rules

  • Attributed: Dormant users who haven't used the app for longer than the defined inactivity period. Retargeting re-engagements and reinstalls are attributed.

  • Not attributed: Active users who open the app and don't exceed the minimum inactivity period are disregarded and not attributed to the retargeting campaign.
