This report lists the referring URLs of the most recent visits to the site.
This allows you to see how people are finding the site. These could be links
from other sites, e-mail messages (read in a browser), search engines, banner ads, or news groups.|
'unknown' is displayed when the user typed the URL directly in their browser
(and so wasn't referred from another site), when a browser fails to report
from where a visitor was referred for security reasons OR referrals from a
link in an email message (not read in a web browser).
Also, if you are a member of a popup (or pop-under) site exchange, your site is usually displayed
in one frame of a 'framed' site on the exchange's domain. When your site is displayed in the frame,
there isn't a referral. In addition, the frame security built into each
web browser will usually block any referral information telling what referred the visitor to
the exchange member's site. Here is a page
that talks more about Site Meter and framed sites.
