Hi guys i have a friend of mine who has a site i noticed once tested with moz that there are 80 duplicate content warnings, for instance Page 1 is http://yourdigitalfile.com/signing-documents.html the warning page is http://www.yourdigitalfile.com/signing-documents.html another example Page 1 http://www.yourdigitalfile.com/ same second page http://yourdigitalfile.com i noticed that the whole website is like the nealry every page has another version in a different url?, any ideas why they dev would do this, also the pages that have received the warnings are not redirected to the newer pages you can go to either one??? thanks very much
