Unsegmentation describes processes that disqualify and remove device profiles from segments. Your ability to remove a device profile from a segment depends on the device option used to create a Profile Merge Rule.
As a reminder, the Device Options are available in the Profile Merge Rules Setup section when you create or edit a Profile Merge Rule.
Device Profile is the default device profile option for a Profile Merge Rule. Audience Manager can remove a device profile from a segment when your Profile Merge Rule uses the Device Profile option. Under these conditions, unsegmentation happens when:
Audience Manager can remove a cross-device ID from a segment when your Profile Merge Rule uses the Current Authenticated Profiles + No Device Profile option. Under these conditions, unsegmentation happens when the cross-device ID no longer qualifies for a segment because updates or changes to the cross-device profile disqualify it. This happens when segment qualification criteria change, or you apply an AND NOT operator to a segment rule, or specify recency and frequency conditions that use the less than/equal to settings. Use cases are described in the Instant Cross-Device Suppression documentation.
Audience Manager can remove multiple device profiles from a segment when your Profile Merge Rule uses a device graph option. Unsegmentation happens when the merged profile of the device from the device graph no longer qualifies for the segment because updates or changes to this merged profile disqualify it from the segment. This happens when segment qualification criteria change, or you apply an AND NOT operator to a segment rule, or specify recency and frequency conditions that use the less than/equal to settings. Use cases are described in the Instant Cross-Device Suppression documentation.
100 device limit for segment evaluation and disqualification.
Audience Manager merges up to 100 devices when evaluating segments with a Profile Merge Rule that uses a device graph. Audience Manager evaluates the current device and up to 99 devices linked to the current device by an authenticated profile (cross-device ID). If the unsegment signal is issued, the current device and additional devices will be removed from the segment in the destination.
