If the sites share a common domain name (e.g. sitea.company.com and
siteb.company.com) then you can obviously use a 1st party cookie for
company.com to track between the sites.



If this is not the case, but assuming the sites are co-operating then this
is something that we (Site Intelligence) can do through the use of
redirections and a central cookie server.

Subject: [webanalytics] Tracking unique visitors across multiple sites?








Does anyone know of an analytics solution that is capable of tracking
and measuring unique visitors across a network of sites without
relying on 3rd party cookies?

(Apologies for the repost and for the cryptic subject of my initial message)

Thanks,
Kara
