Multiple Users/Same Visitor ID

Trying to deterine machine usage behavior.

Hi People,

I have a client that wants to understand individuals rather than just visitors, ...

So that brings up some questions:

Yes, one can use email addresses or have them sign up for something. But, without that... I have not found much discussion of multiple users on a machine to know roughly the % of this that is going on.

When tracking visitors, one is obvisously tracking machine usage as there may be more that one user. In a home, husband, wife and kids,.. at work could be many users on one machine,... etc. I would think in most cases it is just one user per machine, but do not really know.

Has anyone seen any statistics on multiple users per machine? When looking at visitor data, how much of it is individuals? How much isn't?

And, how would you identify visitors data that could be from mulitple users within the existing site visit data?

Thanks for any thoughts you have!

Here's the other side of the coin - single users who visit from multiple machines (home and work, desktop/laptop, etc). Maybe it evens things out :)

Very, very true. But, I'd like to get some scope of the issue, including your additions which I didn't think of. :(

Once I get an idea of how big a problem it is, there may be some way to understand it better outside of registration requirements. That obviously settles the problem but doen't not lead to better understanding of visitor data without registration.

Thanks for the input! :)
