Now I can only see the "Traffic Sources" of "Visits". But what I would like to know is the number of "Unique Visitors" from each referrals. But when I go to "Traffic Sources" -"Referrals" from the left side menu bar it only shows the number of "Visits" Any idea? Or if google analytics doesn't provide this are there other similar tools for it? Thanks.
The same screen shows you the
% New Visits which gives you an indication of how many of the total visits are unique. You can also click
secondary dimension and add
visitor type which will show you new vs returning, again giving you a metric to judge uniques.
