      Hey Guys,

      I had a quick look around however I couldn't find a specific answer to this.

      Currently, the SEOmoz tools come back and show a heap of duplicate content on my site. And there's a fair bit of it.

      However, a heap of those errors are relating to random capitals in the urls.

      for example.

      "www.website.com.au/Home/information/Stuff" is being treated as duplicate content of "www.website.com.au/home/information/stuff" (Note the difference in capitals).

      Anyone have any recommendations as to how to fix this server side(keeping in mind it's not practical or possible to fix all of these links) or to tell Google to ignore the capitalisation?

      Any help is greatly appreciated.

      LM.

        The IIS url-rewrite addon works great!

          From my memory Google does treat urls as case sensitive.

          Best to keep al urls as lower case.

            Thanks for your reply Alan!

            Bing is irrelevant in Belgium 🙂 Maybe marketshare of 0,00005 or so 🙂

            When I look at the SEOMoz crawling reports I panic, but when I look at GWT, I'm happy... The difference is huge.

            So, no sure I will keep on using these reports..

                If Google ignores the mixed usage of capitals in URL's, then why is the SEOMoz reporting it? If it is irrelevant, why not leaving it out?? It takes quite some work to filter out the irrelevant stuff!

                  Thanks Semil - The same duplicates are not showing in Google Webmaster Tools, for instance SEOMoz is showing 639 duplicate page content and 646 duplicate page titles. Webmaster tools is 88 and 37 respectively.

                  Looking into the numbers in SEOmoz again (and they've risen since the original post) there's a huge number which fall under the capitalisation discussed but also some which seem to register as HTTPS and HTTP.

                      Yes its seen as too different urls

                      http://perthseocompany.com.au/seo/reports/violation/the-page-contains-multiple-canonical-formats

                      If you are uisng a windows server (IIS), you can fix this easy by using the IIS url-rewrite addon. it had a rewite as lowercase preset

                        Google does count this as duplicate content. Semil is right. You want to have someone do url rewrites on the server side to 301 these to lowercase.

                          Hi LucasM,

                          Yes its possible by server side that you cant open a url with capital letters if you are using small letters.

                          But I dont think google will talke capitalisation in consideration.

                          Is it showing you in Google webmaster tool in duplicate titles and duplicate descriptions ?

                          If its showing then ask your coder to play with .htaccess to stop opening a url with different small - capital letter combination.

                          Thanks,

                            Will I be flagged for duplicate content by Google?

                            Hi Moz community, Had a question regarding duplicate content that I can't seem to find the answer to on Google. My agency is working on a large number of franchisee websites (over 40) for one client, a print franchise, that wants a refresh of new copy and SEO. Each print shop has their own 'microsite', though all services and products are the same, the only difference being the location. Each microsite has its own unique domain. To avoid writing the same content over and over in 40+ variations, would all the websites be flagged by Google for duplicate content if we were to use the same base copy, with the only changes being to the store locations (i.e. where we mention Toronto print shop on one site may change to Kelowna print shop on another)? Since the print franchise owns all the domains, I'm wondering if that would be a problem since the sites aren't really competing with one another. Any input would be greatly appreciated. Thanks again!

                            Upper and lower case URLS coming up as duplicate content

                            Hey guys and gals, I'm having a frustrating time with an issue. Our site has around 10 pages that are coming up as duplicate content/ duplicate title. I'm not sure what I can do to fix this. I was going to attempt to 301 direct the upper case to lower but I'm worried how this will affect our SEO. can anyone offer some insight on what I should be doing? Update:  What I'm trying to figure out is what I should do for our URL's. For example, when I run an audit I'm getting two different pages: aaa.com/BusinessAgreement.com and also aaa.com/businessagreement.com. We don't have two pages but for some reason, Google thinks we do.

                            Country Code Top Level Domains & Duplicate Content

                            Hi looking to launch in a new market, currently we have a .com.au domain which is geo-targeted to Australia. We want to launch in New Zealand which is ends with .co.nz If i duplicate the Australian based site completely on the new .co.nz domain name, would i face duplicate content issues from a SEO standpoint?
                            Even though it's on a completely separate country code. Or is it still advised tosetup hreflang tag across both of the domains? Cheers.

                            Woocommerce SEO & Duplicate content?

                            Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

                            Duplicate Content www vs. non-www and best practices

                            I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess Rule for duplicate content removal : www.domain.com vs domain.com RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
                            RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC] The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com I wonder if this is causing issues in SERPS.  If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites. -----Can you comment on whether this is a best practice for all domains?
                            -----I've run a report for backlinks.  If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?

                            Could you use a robots.txt file to disalow a duplicate content page from being crawled?

                            A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO. I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?

                            Duplicate Content | eBay

                            My client is generating templates for his eBay template based on content he has on his eCommerce platform. I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay? Update: I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content. The question is now: should I add it or not? UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting. Anyone else have feedback?
