Cookies and the Marketing Cloud ID Service

[AEM_Forum]

Hi all,

I am referring to the URL Cookies and the Marketing Cloud ID Service  on this subject.

If MCID is implemented as a cookie, it is limited to the machine used for browsing.

What happens if the same user uses a different machine to access the same site?

Since the cookie does not exist on the new machine, will it crate a new MCID and cookie?

In such a case, the very purpose of MCID is defeated.

Appreciate all your responses.

Thanks,

Rama.

Rama,

Yes, MCID is cookie based. While it isn't perfect, it's a major improvement over the legacy solution specific identification.

You can accomplish cross device targeting if the user logs in and you set the Customer ID. Otherwise, you are correct if a user uses two different devices and does not log in, there is no way to know they are the same user. This problem is not unique to Adobe solutions.

Cheers,
