Email Forward Link: If there was one category of links I would wish to move higher on this list, this would be it. These are the referral URLs that come through with very strange configurations, but take you back to a secure network or webmail service, meaning that a URL for a post or my blog was emailed from one person to another and they clicked directly on the link in the email to get to my blog. This is the type of link I strive for – to be viral enough to have a reader send a post to another reader. Obviously, it’s not fool proof as many folks might cut and paste the URL instead of clicking directly … but this is emblematic of the type of hidden blog traffic that only becomes clear once you delve into your stats.
