      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.

              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!

              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.

              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

              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?

              Tabs and duplicate content?

              We own this site http://www.discountstickerprinting.co.uk/ and just a little concerned as I right clicked open in new tab on the tab content section and it went to a new page For example if you right click on the price tab and click open in new tab you will end up with the url
              http://www.discountstickerprinting.co.uk/#tabThree Does this mean that our content is being duplicated onto another page? If so what should I do?

              Best practice for duplicate website content: same root domain name but different extension

              Hi there I have a new client who has two websites: http://www.bayofislandsteambuilding.co.nz
              http://www.bayofislandsteambuilding.org.nz They are the same in every regard apart from the domain extension (.co.nz & .org.nz) which is likely to be causing them issues with Google ranking given the huge amount of duplicate content. What is the best practice approach to fixing this? Normally, if I was starting from scratch, I would set one of the extensions as an alias which redirects to the main domain. Thanks in advance. Laurie

              International SEO - cannibalisation and duplicate content

              Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant  drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian

              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.
