      Hello,

      We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content.

      What we have done so far:

      • Choosing the best-selling color variation (our "master product")
      • Adding a rel="canonical" to every variation (with our "master product" as the canonical URL)

      In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do?

      Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change)

      Thank you in advance

        Thank you for your answer. I would love to do it this way, unfortunately our current system wouldn't allow it. With more than 5000 products on our website, different content for each color variation would be time consuming.

        My question was about "noindex,follow" on children products (with the proper canonicalisation) and its SEO impact. But my guess is that canonicalisation should be enough to address the issue.

          Hello,

          If color is the main variation in the products, can you just set those as options, so each color is not a separate page? Then you just have one item and the user just selects a different color from that page. That is really the way this should be done to avoid any duplicate content issues. The other idea would just be to write different content for the pages, which if they are different products, they should already have different content already.

          Hope that helps.

            Thank you for your answer. Great job on this guide! Actually, we already did this on our product listing pages (a combination of next/prev, noindex/follow and canonicals). It worked great.

            However, our current issue is about our product pages. I'm wondering if a combination of canonicalisation and noindex on secondary content would be relevant.

              Hi there,

              You may have a more complex pagination issue. My former colleague wrote a good guide to this sort of e-commerce pagination / canonicalisation problem a few months ago. It may qualify as one of the non-boring reads on the subject 😉 Do you see a solution here that looks good for you? - http://www.ayima.com/seo-knowledge/conquering-pagination-guide.html

                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 %}

                Disallow: /jobs/? is this stopping the SERPs from indexing job posts

                Hi,
                I was wondering what this would be used for as it's in the Robots.exe of a recruitment agency website that posts jobs. Should it be removed? Disallow: /jobs/?
                Disallow: /jobs/page/*/ Thanks in advance.

                Same content, different languages. Duplicate content issue? | international SEO

                Hi, If the "content" is the same, but is written in different languages, will Google see the articles as duplicate content?
                If google won't see it as duplicate content. What is the profit of implementing the alternate lang tag?Kind regards,Jeroen

                Same product in different categories and duplicate content issues

                Hi,I have some questions related to duplicate content on e-commerce websites. 1)If a single product goes to multiple categories (eg. A black elegant dress could be listed in two categories like "black dresses" and "elegant dresses") is it considered duplicate content even if the product url is unique? e.g www.website.com/black-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/elegant-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/black-elegant-dress unique url > this is the way my products urls look like Does google perceive this as duplicated content? The path to the content is only one, so it shouldn't be seen as duplicated content, though the product is repeated in different categories.This is the most important concern I actually have. It is a small thing but if I set this wrong all website would be affected and thus penalised, so I need to know how I can handle it. 2- I am using wordpress + woocommerce. The website is built with categories and subcategories. When I create a product in the product page backend is it advisable to select  just the lowest subcategory or is it better to select both main category and subcategory in which the product belongs? I usually select the subcategory alone.  Looking forward to your reply and suggestions. thanks

                Duplicate content on URL trailing slash

                Hello, Some time ago, we accidentally made changes to our site which modified the way urls in links are generated. At once, trailing slashes were added to many urls (only in links). Links that used to send to
                example.com/webpage.html Were now linking to
                example.com/webpage.html/ Urls in the xml sitemap remained unchanged (no trailing slash). We started noticing duplicate content (because our site renders the same page with or without the trailing shash). We corrected the problematic php url function so that now, all links on the site link to a url without trailing slash. However, Google had time to index these pages. Is implementing 301 redirects required in this case?

                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.

                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.

                Duplicate Titles caused by multiple variations of same URL

                Hi. Can you please advise how I can overcome this issue. Moz.com crawle is indicating I have 100's of Duplicate Title tag errors. However this is caused because many URL's have been indexed multiple times in Google. For example. www.abc.com
                www.abc.com/?b=123 www.abc.com/ www.abc.com/?b=654 www.abc.com/?b=875 www.abc.com/index.html What can I do to stop this issue being reported as duplictae Titles, as well as content? I was thinking maybe I can use Robots.txt to block various query string parameters. I'm Open to ideas and examples.
