**These are duplicate URLs that we can't figure out how they are getting created. ** I want to be sure we are talking about the same thing here. When I hear "duplicate URL" I am thinking of multiple URLs which point to the same web page. Depending on how your site is set up it is possible to have many different URLs point to the same web page. Possible examples are: www.mydomain.com/tennis-rackets www.mydomain.com/tennis-rackets/ mydomain.com/tennis-rackets?sort=asc Above are three examples of URLs which can all lead to the same page. You can have dozens of URLs all lead to a page with identical content. How these issues get resolved depends upon how they were created. The best tool to help you figure this out is your crawl report. Use the SEOmoz crawl tool, then examine the crawl report. It can be a bit overwhelming at first, but you can narrow things down real fast if you use Excel. Select the header row for your data (begins with the URL field), then select Data > Filter > Auto Filter from the menu. Then start by looking at fields such as "Duplicate Page Content", "URLs with duplicate content", etc. Simply choose YES in the drop down menu to filter for that particular data. This will help you uncover the source of these issues. The URLs in my example should all be 301'd or canonicalized to the primary page to resolve the duplication issue.
