We have an PR3 e commerce site with some 40,000 pages. Most being in the suplemental index.
We use quite a few pay per click sites and have a referer string in their linking url to monitor click traffic. When the user clicks through to our site the referer string is removed and the user gets a 301 redirect to the required page. This was done to avoid any possible duplicate page issues.
What we are now thinking is that even with the redirect there are many versions of the page name linking in. i.e. example.com?product=xyz&Refererid=abc which redirects to example.com?product=xyz so we are not getting any credit for all these referers.
Does this sound like a credible theory? and has anybody ever overcome this problem? If we used a href instead would google only see the desired url? example.com?product=xyz#Refererid=abc
