I am really not sure wheather it's an appropriate place for the thread... but I see rather strange referrers, bringing traffic to a site, like: b2.mail.yahoo.com mail.google.com mail.lycos.com and so on. What are they? Is this the case when a link to a site was mailed? Thanx in advance for answers
They are when the visitor came from their email account. It can be from PPC adverts or from a link in an email. Maybe even somebody reading your RSS feed by email.
