      I have a question. I was wondering, if it was possible to set up a rel canonical. When I can't access the non canonical pages? For example, my site as at www.site.com , but the non cannocail is at site.com is their any way to set thet up without actually edting it at site.com ? Thanks for your help

        site.com and site.com/index.html are both loading index.html  So open Index.html, add the canonical tag back to your preferred version and you're done.

        If you're saying that you want the link to be something different, that depends on how the site is setup, whether you can change the "home" button or whatnot. In Wordpress's new menus this is simple. In other themes, not so much. In other CMS, I don't know because "it depends."

          Hi Matt,

          Yes the duplicate is coming from index.html . So, when you click back to the homepage it goes to that. How would you suggest I get rid of that? Thanks for your help.

            I'm confused. Assuming your site is at www.site.com and site.com, the duplicate is coming from a file, usually index.html or index.php, yes?  But it's the same index.html file.  So if you setup rel=canonical in index.html, both site.com and www.site.com will have a canonical on it.

            (Or I'm missing something.)

              If there's no way to access site.com why will you set a canonical?

              If, for example, your sites serves the same content on site.com and www.site.com what you need is a "global" 301 redirect from site.com to www.site.com to avoid duplicate issues. As the file is the same in both domains, a canonical would help, but not appropriate in that case.

              Is that what you need?

                How (or if) to apply re canonical tags to Shopify?

                Anyone familiar with Shopify will understand the problems of their directory structure. Every time you add a product to a 'collection' it essentially creates a duplicate. For example... https://www.domain.com/products/product-slim-regular-bikini may also appear as: https://www.domain.com/collections/all/products/product-slim-regular-bikini https://www.domain.com/collections/new-arrivals/products/product-slim-regular-bikini https://www.domain.com/collections/bikinis/products/product-slim-regular-bikini etc, etc It's not uncommon to have up to six duplicates of each product. So my question is twofold: Firstly, should I worry about this from an SEO point of view? I understand the desire to minimise potential duplicate content issues and also in focussing the 'juice' on just one page per product. But I also planned on trying to build the authority of the collection pages. If I request Google not to index the product pages which link off the collections, does this not devalue these collections pages? Secondly, I understand the correct way to fix these is using 'rel canonical' tags, but I'm not clear about HOW to actually do this. Shopify support has not been very helpful. They have provided two different instructions, so just added to the confusion (see below). Shopify instruction #1: Add the following to the theme.liquid file... <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 %} Shopify instruction #2: Add the following to each individual product page... So, can anyone help clarify: The best strategic approach to this inherent SEO issue with Shopify (besides moving to another platform!)? and If 'rel canonical' tags is the way to go, exactly where and how to apply them? Regards, Murray

                Should I set up no index no follow on low quality pages?

                I know it is a good idea for duplicate pages, blog tags, etc. but I remember somewhere that you can help the overall link juice of a website by adding no index no follow or no index follow low quality content pages of your website. Is it still a good idea to do this or was it never a good idea to begin with? Michael

                Attribution of port number to canonical links...ok?

                Hi all A query has recently been raised internally with regard to the use of canonical links. Due to CMS limitations with a client who's CMS is managed by a third party agency, canonical links are currently output with the port number attributed, e.g. example.com/page:80 ...as opposed to the correct absolute URL: example.com/page Note port number are not attributed to the actual page URLs. We have been advised that this canonical link functionality cannot be amended at present. My personal interpretation of canonical link requirements is that such a link should exactly match the absolute URL of the intended destination page, my query is does this extend to the attribution of port number to URLs. Is the likely impact of the inclusion of such potentially incorrect URLs likely to be the same as purely incorrect canonical links. Thanks

                Using Canonical URL to poin to an external page

                I was wondering if I can use a canonical URL that points to a page residing on external site? So a page like:
                www.site1.com/whatever.html will have a canonical link in its header to www.site2.com/whatever.html. Thanks.

                Exact Syntax for Canonical to PDFs for Windows Server

                Hi There, I have got in my web several PDFs with the same content of the HTML version. Thus I need to set up a canonical for each of them in order to avoid duplicate content. In particular, I need to know how to write the exact syntax for the windows server (web.config) in order to implement the canonical to PDF. I surfed the web but it seems I cannot find this piece of info anywhere Thanks a lot!!

                Why is "Noindex" better than a "Canonical" for Pagination?

                "Noindex" is a suggested pagination technique here: http://searchengineland.com/the-latest-greatest-on-seo-pagination-114284, and everyone seems to agree that you shouldn't canonicalize all pages in a series to the first page, but I'd love if someone can explain why "noindex" is better than a canonical?

                Should you use a canonical tag on translated content in a multi-language country?

                A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
                At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???

                Rel=canonical tag on original page?

                Afternoon All,
                We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short. We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself? What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original. We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?
