      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.

              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.

              Duplicate content in Shopify - subsequent pages in collections

              Hello everyone! I hope an expert in this community can help me verify the canonical codes I'll add to our store is correct. Currently, in our Shopify store, the subsequent pages in the collections are not indexed by Google, however the canonical URL on these pages aren't pointing to the main collection page (page 1), e.g. The canonical URL of page 2, page 3 etc are used as canonical URLs instead of the first page of the collections. I have the canonical codes attached below, it would be much appreciated if an expert can urgently verify these codes are good to use and will solve the above issues? Thanks so much for your kind help in advance!! -----------------CODES BELOW--------------- <title><br /> {{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>
              {% if page_description %} {% endif %} {% if current_page != 1 %} {% else %} {% endif %}
              {% if template == 'collection' %}{% if collection %}
              {% if current_page == 1 %} {% endif %}
              {% if template == 'product' %}{% if product %} {% endif %}
              {% if template == 'collection' %}{% if collection %} {% endif %}

              Duplicate Content through 'Gclid'

              Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

              Real Estate MLS listings - Does Google Consider duplicate content?

              I have a real estate website. The site has all residential properties for sale in a certain State (MLS property listings). These properties also appear on 100's of other real estate sites, as the data is pulled from a central place where all Realtors share their listings. Question: will having these MLS listings indexed and followed by Google increase the ratio of duplicate vs original content on my website and thus negatively affect ranking for various keywords? If so, should I set the specific property pages as "no index, no follow" so my website will appear to have less duplicate content?

              Duplicate Content on Wordpress b/c of Pagination

              On my recent crawl, there were a great many duplicate content penalties.  The site is http://dailyfantasybaseball.org. The issue is: There's only one post per page.  Therefore, because of wordpress's (or genesis's) pagination, a page gets created for every post, thereby leaving basically every piece of content i write as a duplicate. I feel like the engines should be smart enough to figure out what's going on, but if not, I will get hammered. What should I do moving forward? Thanks!

              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?

              How to resolve Duplicate Page Content issue for root domain & index.html?

              SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
