We have been using the MC Visitor ID Service for some time now. When we first hooked it up, the advice given regarding setting customer ids was not to bother because they weren't used for anything at that time. I found this same information on some blogs written by Adobe folks and in talking with our internal Adobe contacts.
Is this still the case? It seems that if I associated, say, my customer'd account number with the the call that the service could use that to associate that same user across devices. None of the documentation I can find by searching specifically says how that value is or is not used, other than by detailing the setCustomerIds() function. I have tried asking our internal Adobe contacts the same question and, again, crickets.
So, in a nutshell: If we are not using Audience Manager, is there any benefit to be realized by including customer ids with the MC Visitor ID service?
Thank you.
