We're hoping that this may contain something relating to segments but have not been able to find any examples of what this field would contain when populated.
Given its definition (string 255) it seems unlikely that it would/could contain a full list of segments that a visit had fallen into.
Can someone point at some definitive documentation?
Thanks in advance!
The column is going to contain a list of Audience Manager segment ID's that the visitor belongs to.
