when I look at the Target Activities Report regarding our recent A/B Tests, I have a varying amount of visitors marked as "unspecified". This number ranges sometimes between 25% and 80% (of unique visitors who are counted as "unspecified"). I am aware, that Adobe Target might take up to 36 hours until traffic is correctly classified regarding one of the experiences. But then, at least for a test which has been deactivated already 1 week ago, the classification should be complete, shouldn't it?
Any idea where this comes from or how to solve it?
There are a number of reasons why visitors would show as "Unspecified"
Per Troubleshoot A4T
There are several reasons why this could happen:
If data is still coming as unspecified, kindly open a clientcare ticket so that it can be debugged further.
If you have waited for 36 hours and the activity data still shows up as unspecified, there might be something else causing the issue: ranging from implementation to activity set up, etc. I encourage you to open a Client Care ticket so we can take a look, especially if this happens across multiple activities.
