      Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs.

      1. We've instituted canonical tags site wide.

      2. We are using the parameters function in Webmaster Tools.

      3. We are using 301 redirects on all of the obsolete URLs

      4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals.

      5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed.

      None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical.

      Any ideas on how to clean up the mess?

        Where this is  appearing the most is on cross domain canonicals. We have duplicate content across 2 websites, and we've canonicaled some pages from Site A to Site B, and some from Site B to Site A. In theory, pages that were canonicaled to the other domain should be deindexed. When I run a rankings report, I see pages for the wrong domain ranking, a month later. They are pages with parameters, or old URLs that we've changed. It's like a game of whack a mole. Every time we get a page deindexed, a duplicate with a different parameter takes its place. And this is in spite of calling out these parameters in GWT.

        What I imagine is happening is that we have several URLs for the same page indexed. When Google crawls our site, it is correctly canonicaling the page it crawls. In the rankings, however, Google is probably pulling a duplicate page out of its index, and ranking it without crawling it. If it was crawling it, Google would see the canonical tag, and not rank it. So we have an ongoing battle to get Google to crawl the page it just pulled out of its index to see the the canonical tag.

        The reason for all this is that when a page cross domain canonicals correctly, the rankings for the duplicate page on the other site goes up dramatically. As long as Google keeps ranking the wrong pages, we don't get the rankings bump on the other site.

          Are you basing this on a site: search? It's fairly common for URLs to appear in a site: search that otherwise will not appear for any actual searches. Are the undesirable versions of the URLs getting any search traffic?

            Yes, as Patrick said, surprisingly often something like this is a result of a simple oversight because we have been looking at the same code over and over...

            Do you have access to Screaming Frog? You could crawl your site and see whether redirects/canonicals are behaving as you expected.

            Have you taken a look at the html of one of the incorrectly indexed pages when it is loaded in your browser? Can you see the canonical? If you try going to a redirected page, does it redirect? [I know--way to obvious, but sometimes it is good to start at the beginning again when we can't root out an issue.]

            Another culprit in these cases can be internal links. Do you link internally using any of the undesirable URLs? That can send a message to Google that those URLs are still in play. Again, you can use Screaming Frog to find those strings.

              It sounds like part of the problem may be the sitemaps you're sending. By including duplicates in a sitemap, you're basically telling Google that each version of the page is valid. I would remove them and resubmit a sitemap with only the canonical versions you want indexed and see if that helps.

                Hi there

                Are you sure you are using all of the tools above properly? Not saying you're not but people make mistakes and it's just something to look into.

                When did you implement all of the changes? Was it recently or was it a long time ago?

                How is your organic traffic and rankings? Did you check if you have a manual action at all?

                Let me know - thanks!

                  How can I avoid duplicate content for a new landing page which is the same as an old one?

                  Hello mozers! I have a question about duplicate content for you... One on my clients pages have been dropping in search volume for a while now, and I've discovered it's because the search term isn't as popular as it used to be. So... we need to create a new landing page using a more popular search term. The page which is losing traffic is based on the search query "Can I put a solid roof on my conservatory" this only gets 0-10 searches per month according to the keyword explorer tool. However, if we changed this to "replacing conservatory roof with solid roof" this gets up to 500 searches per month. Muuuuch better! The issue is, I don't want to close down and re-direct the old page because it's got a featured snippet and sits in position 1. So I'd like to create another page instead... however, as the two are effectively the same content, I would then land myself in a duplicate content issue. If I were to put a rel="canonical" tag in the original "can I put a solid roof...." page but say the master page is now the new one, would that get around the issue?

                  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 %}

                  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

                  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!

                  Duplicate Content on Press Release?

                  Hi, We recently held a charity night in store. And had a few local celebs turn up etc... We created a press release to send out to various media outlets, within the press release were hyperlinks to our site and links on certain keywords to specific brands on our site. My question is, should we be sending a different press release to each outlet to stop the duplicate content thing, or is sending the same release out to everyone ok? We will be sending approx 20 of these out, some going online and some not. So far had one local paper website, a massive football website and a local magazine site. All pretty much same content and a few pics. Any help, hints or tips on how to go about this if I am going to be sending out to a load of other sites/blogs? Cheers
