We've recently started exploring our Adobe Analytics and Adobe Target data at a new level with the addition of a data scientist to our team. She has uncovered something unexpected. She is finding multiple customer ids from our CRM system associated with a single mcvisid. We have a customer portal online where we have conversions. Why would this be?
If you are referring to mboxMCGVID, then the explanation can be that the mboxMCGVID value belongs to a shared device. Every user has its own CRM ID while the Experience Cloud ID identifies all of them as a single device as the method is based on cookies.
To target activities to a persona rather than to a device consider setting CRM ID with one of the following options:
- Audience Manager with Declared ID or Customer ID
