I am showing a lot of errors in my SEOmoz reports for duplicate content and duplicate titles, many of which appear to be related to capitalization vs non-capitalization in the URL.
Case in point, if a URL contains a lower character, such as:
http://www.gallerydirect.com/art/product/allyson-krowitz/distinct-microstructure-i
as opposed to the same URL having an upper character in the structure:
http://www.gallerydirect.com/art/product/allyson-krowitz/distinct-microstructure-I
I am finding that some of the internal links on the site use the former structure and other links use the latter structure. These show as duplicate title/content in the SEOmoz reports, but they don't appear as duplicate titles in Webmaster Tools.
My question is, should I try to work with our developers to create a script to change all of the content with cap letters in the destination links internally on the site, or is this a non-issue since it doesn't appear in Webmaster Tools?
