Activity collisions

The Collisions tab on the Activity Overview page in Adobe Target lists activity collisions on your site.

An activity collision occurs when multiple activities are set up to deliver content to the same page. If an activity collision occurs, you might not see the expected content on your page.

The Collisions tab is available on the activity overview page and can inform you if your activity contains potential collisions.

To access the Collisions tab, click Activities > click the desired activity from the list > then click Collisions in the left rail.

All activities on the same URL are listed, regardless of any audience targeting in each activity. Open this tab for a list of activities that might be colliding. If the collision alters the expected experience, edit the activity.

The Collisions list helps you:

The Collisions list shows every Target scenario where the mbox is used and that uses the same URL. For each potential collision, the list shows the Activity URL, the mbox name where the collision might occur, and any activities that match both of those criteria. If there are multiple mboxes, they are each listed.

The list shows the status and priority of each potential collision, along with other information. You can use the status and priority to help you determine the likelihood of a collision occurring. Consider two activities that might collide. If one activity is not currently active, a collision cannot occur. A collision is only possible if the inactive activity becomes active. If the potential collision is between two live activities with the same priority and the same audience, a collision occurs. You can change the priority or status to prevent the collision.

If the audiences are different, there is still a potential collision because it’s possible a particular visitor could belong to multiple audiences.
