I've been asked to investigate whether it's possible to determine from our website analytics which companies are viewing our site. I've made enquiries and it appeared that no information could be captured about the identity of a visitor as I'd just get an anonymous IP address that would lead me to the ISP's details and not to any details identifying the visitor.
However, I've been looking at the "Clicky Web Analytics" website and they claim to be able to give stats on the "Visitor organizations (e.g. Microsoft Corp)".
Their website is here: http://getclicky.com
So, can anyone tell me definitively whether it is indeed possible to capture information identifying the company of the visitor to my website (and for that matter any similar info!), and if so, how this is possible?
