      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.

              Duplicate content due to parked domains

              I have a main ecommerce website with unique content and decent back links. I had few domains parked on the main website as well specific product pages. These domains had some type in traffic. Some where exact product names.  So main main website www.maindomain.com had domain1.com , domain2.com parked on it. Also had domian3.com parked on www.maindomain.com/product1. This caused lot of duplicate content issues. 12 months back, all the parked domains were changed to 301 redirects. I also added all the domains to google webmaster tools. Then removed main directory from google index. Now realize few of the additional domains are indexed and causing duplicate content. My question is what other steps can I take to avoid the duplicate content for my my website 1. Provide change of address in Google search console. Is there any downside in providing change of address pointing to a website? Also domains pointing to a specific url , cannot provide change of address 2. Provide a remove page from google index request in Google search console. It is temporary and last 6 months. Even if the pages are removed from Google index, would google still see them duplicates? 3. Ask google to fetch each url under other domains and submit to google index. This would hopefully remove the urls under domain1.com and doamin2.com eventually due to 301 redirects. 4. Add canonical urls for all pages in the main site. so google will eventually remove content from doman1 and domain2.com due to canonical links. This wil take time for google to update their index 5. Point these domains elsewhere to remove duplicate contents eventually. But it will take time for google to update their index with new non duplicate content. Which of these options are best best to my issue and which ones are potentially dangerous? I would rather not to point these domains elsewhere. Any feedback would be greatly appreciated.

              Case Sensitive URLs, Duplicate Content & Link Rel Canonical

              I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

              No-index pages with duplicate content?

              Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

              Duplicate content on sites from different countries

              Hi, we have a client who currently has a lot of duplicate content with their UK and US website. Both websites are geographically targeted (via google webmaster tools) to their specific location and have the appropriate local domain extension. Is having duplicate content a major issue, since they are in two different countries and geographic regions of the world? Any statement from Google about this? Regards, Bill

              How do I geo-target continents & avoid duplicate content?

              Hi everyone, We have a website which will have content tailored for a few locations: USA: www.site.com
              Europe EN: www.site.com/eu
              Canada FR: www.site.com/fr-ca Link hreflang and  the GWT option are designed for countries. I expect a fair amount of duplicate content; the only differences will be in product selection and prices. What are my options to tell Google that it should serve www.site.com/eu in Europe instead of www.site.com? We are not targeting a particular country on that continent. Thanks!

              News sites & Duplicate content

              Hi SEOMoz I would like to know, in your opinion and according to 'industry' best practice, how do you get around duplicate content on a news site if all news sites buy their "news" from a central place in the world? Let me give you some more insight to what I am talking about. My client has a website that is purely focuses on news. Local news in one of the African Countries to be specific. Now, what we noticed the past few months is that the site is not ranking to it's full potential. We investigated, checked our keyword research, our site structure, interlinking, site speed, code to html ratio you name it we checked it. What we did pic up when looking at duplicate content is that the site is flagged by Google as duplicated, BUT so is most of the news sites because they all get their content from the same place. News get sold by big companies in the US (no I'm not from the US so cant say specifically where it is from) and they usually have disclaimers with these content pieces that you can't change the headline and story significantly, so we do have quite a few journalists that rewrites the news stories, they try and keep it as close to the original as possible but they still change it to fit our targeted audience - where my second point comes in. Even though the content has been duplicated, our site is more relevant to what our users are searching for than the bigger news related websites in the world because we do hyper local everything. news, jobs, property etc. All we need to do is get off this duplicate content issue, in general we rewrite the content completely to be unique if a site has duplication problems, but on a media site, im a little bit lost. Because I haven't had something like this before. Would like to hear some thoughts on this. Thanks,
              Chris Captivate

              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?
