      We have an ecommerce website with 700 pages. Due to the implementation of filters, we are seeing upto 11,000 pages being indexed where the filter tag is apphended to the URL. This is causing duplicate content issues across the site.

      We tried adding "nofollow" to all the filters, we have also tried adding canonical tags, which it seems are being ignored. So how can we fix this?

      We are now toying with 2 other ideas to fix this issue;

      1. adding "no index" to all filtered pages

      2. making the filters uncrawble using javascript

      Has anyone else encountered this issue? If so what did you do to combat this and was it successful?

        Thank you both Lesley & Jim!

        This tool is exactly what we needed! Fingers crossed now we have resolved the issues we had with all that duplicate content.

        How long has the parameter tool been available?? I never even knew it existed!

          Check your Google Webmaster Tools and see if you need to use the Parameter tool.  There are settings there that you can use to tell google not to index parameters.  You can also confirm that Google is not under-indexing your site, in which case you don't have to worry about the parametered URLs at all. If you have canonical tags in place that will do the trick.

              SEM Rush & Duplicate content

              Hi SEMRush is flagging these pages as having duplicate content, but we have rel = next etc implemented: https://www.key.co.uk/en/key/brand/bott https://www.key.co.uk/en/key/brand/bott?page=2 Or is it being flagged as they're just really similar pages?

              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.

              Trailing Slashes for Magento CMS pages - 2 URLS - Duplicate content

              Hello, Can anyone help me find a solution to Fixing and Creating Magento CMS pages to only use one URL  and not two URLS? www.domain.com/testpage www.domain.com/testpage/ I found a previous article that applies to my issue, which is using htaccess to redirect request for pages in magento 301 redirect to slash URL from the non-slash URL.  I dont understand the syntax fully in htaccess , but I used this code below. This code below fixed the CMS page redirection but caused issues on other pages, like all my categories and products with this error: "This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS" Assuming you're running at domain root.  Change to working directory if needed. RewriteBase / # www check If you're running in a subdirectory, then you'll need to add that in to the redirected url (http://www.mydomain.com/subdirectory/$1 RewriteCond %{HTTP_HOST} !^www. [NC]
              RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301,L] Trailing slash check Don't fix direct file links RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !(.)/$
              RewriteRule ^(.)$ $1/ [L,R=301] Finally, forward everything to your front-controller (index.php) RewriteCond %{REQUEST_FILENAME} !-f
              RewriteCond %{REQUEST_FILENAME} !-d
              RewriteRule .* index.php [QSA,L]

              PDF for link building - avoiding duplicate content

              Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.

              How to Remove Joomla Canonical and Duplicate Page Content

              I've  attempted to follow advice from the Q&A section. Currently on the site www.cherrycreekspine.com, I've edited the .htaccess file to help with 301s - all pages redirect to www.cherrycreekspine.com. Secondly, I'd added the canonical statement in the header of the web pages. I have cut the Duplicate Page Content in half ... now  I have a remaining 40 pages to fix up. This is my practice site to try and understand what SEOmoz can do for me. I've looked at some of your videos on Youtube ... I feel like I'm scrambling around to the Q&A and the internet to understand this product. I'm reading the beginners guide.... any other resources would be helpful.

              Can PDF be seen as duplicate content? If so, how to prevent it?

              I see no reason why PDF couldn't be considered duplicate content but I haven't seen any threads about it. We publish loads of product documentation provided by manufacturers as well as White Papers and Case Studies. These give our customers and prospects a better idea off our solutions and help them along their buying process. However, I'm not sure if it would be better to make them non-indexable to prevent duplicate content issues. Clearly we would prefer a solutions where we benefit from to keywords in the documents. Any one has insight on how to deal with PDF provided by third parties? Thanks in advance.
