      I implemented rel=canonical on our pages which helped a lot, but my latest Moz crawl is still showing lots of duplicate page titles (2,000+).

      There are other ways to get to this page (depending on what feature you clicked, it will have a different URL) but will have the same page title.

      Does having rel=canonical in place fix the duplicate page title problem, or do I need to change something else? I was under the impression that the canonical tag would address this by telling the crawler which URL was the URL and the crawler would only use that one for the page title.

        Hello,

        I also have a similar problem. Please can you tell me if having duplicate page titles in Moz is an issue as I also have rel= canonical in place.

        Thanks

          If you can direct message me which campaign you're talking about, I can take a look.

            Hi there,

            Any news on this topic yet?
            I also have a lot duplicate page titles.
            Even dough we use canonical tags on the pages. Moz sees them as duplicate page titles.

            Even if the search engines recognize these canonical tags and don't see those pages as duplicate page titles, I still see them in my Moz reports. Which makes it difficult to see legitimate duplicate page titles.

            Any suggestions?

              Can you private message me (via the site) and tell me the URL - I'll check the campaign and ask the team, in case we've got a bug.

                Any word from the SEOMoz product team on this issue? We recently added a number of "view all" category pages within an e-commerce site that our weekly crawl report is now reporting as having duplicate titles, even though we have rel=canonical tags in place.

                  From a broader sense, in terms of Google, yes - the canonical tag will also help alleviate duplicate META data. In our system, though, I'm honestly not 100% sure - I'm going to check with the product team.

                        Rel Canonical should help with the issue. You should also go into google webmaster tools and put in all your URL parameters, so the crawler has a better idea of whats going on with being able to get to a particular resource with several URL variations.

                          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 %}

                          What are best page titles for sub-folders or sub-directories? Same as website?

                          Hi all, We always mention "brand & keyword" in every page title along with topic in the website, like "Topic | vertigo tiles". Let's say there is a sub-directory with hundreds of pages...what will be the best page title practice in mentioning "brand & keyword" across all pages of sub-directory to benefit in-terms if SEO? Can we add "vertigo tiles" to all pages of sub-directory? Or we must not give same phrase? Thanks,

                          Switching from HTTP to HTTPS: 301 redirect or keep both & rel canonical?

                          Hey Mozzers, I'll be moving several sites from HTTP to HTTPS in the coming weeks (same brand, multiple ccTLDs). We'll start on a low traffic site and test it for 2-4 weeks to see the impact before rolling out across all 8 sites. Ideally, I'd like to simply 301 redirect the HTTP version page to the HTTPS version of the page (to get that potential SEO rankings boost). However, I'm concerned about the potential drop in rankings, links and traffic. I'm thinking of alternative ways and so instead of the 301 redirect approach, I would keep both sites live and accessible, and then add rel canonical on the HTTPS pages to point towards HTTP so that Google keeps the current pages/ links/ indexed as they are today (in this case, HTTPS is more UX than for SEO). Has anyone tried the rel canonical approach, and if so, what were the results? Do you recommend it? Also, for those who have implemented HTTPS, how long did it take for Google to index those pages over the older HTTP pages?

                          Case Sensitive URLs, Duplicate Content & Link Rel Canonical

                          I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

                          When is it recommended to use a self referencing rel "canonical"?

                          In what type of a situation is it the best type of practice to use a self referencing rel "canonical" tag? Are there particular practices to be cautious of when using a self referencing  rel "canonical" tag? I see this practice used mainly with larger websites but I can't find any information that really explains when is a good time to make use of this practice for SEO purposes. Appreciate all feedback. Thank you in advance.

                          How do I get rel='canonical' to eliminate the trailing slash on my home page??

                          I have been searching high and low. Please help if you can, and thank you if you spend the time reading this. I think this issue may be affecting most pages. SUMMARY: I want to eliminate the trailing slash that is appended to my website. SPECIFIC ISSUE: I want www.threewaystoharems.com to showing up to users and search engines without the trailing slash but try as I might it shows up like www.threewaystoharems.com/ which is the canonical link. WHY?  and I'm concerned my back-links to the link without the trailing slash will not be recognized but most people are going to backlink me without a trailing slash. I don't want to loose linkjuice from the people and the search engines not being in consensus about what my page address is. THINGS I"VE TRIED: (1) I've gone in my wordpress settings under permalinks and tried to specify no trailing slash. I can do this here but not for the home page. (2) I've tried using the SEO by yoast to set the canonical page. This would work if I had a static front page, but my front page is of blog posts and so there is no advanced page settings to set the canonical tag. (3) I'd like to just find the source code of the home page, but because it is CSS, I don't know where to find the reference.  I have gone into the css files of my wordpress theme looking in header and index and everywhere else looking for a specification of what the canonical page is. I am not able to find it. I'm thinking it is actually specified in the .htaccess file. (4) Went into cpanel file manager looking for files that contain Canonical. I only found a file called canonical.php . the only thing that seemed like it was worth changing was changing line 139 from $redirect_url = home_url('/');  to $redirect_url = home_url('');       nothing happened. I'm thinking it is actually specified in the .htaccess file. (5) I have gone through the .htaccess file and put thes 4 lines at the top (didn't redirect or create the proper canonical link) and then at the bottom of the file  (also didn't redirect or create the proper canonical link) :   RewriteEngine on
                          RewriteCond %{HTTP_HOST} ^([a-z.]+)?threewaystoharems.com$ [NC]
                          RewriteCond %{HTTP_HOST} !^www. [NC]
                          RewriteRule .? http://www.%1threewaystoharems.com%{REQUEST_URI} [R=301,L] Please help friends.

                          Artist Bios on Multiple Pages: Duplicate Content or not?

                          I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution?  Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

                          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?
