          I’m an SEO for an ecommerce site that sells shoes

          I have duplicate pages for different colors of the same product (unique URL for each color),

          Conventionally I have added canonical tags for each page, which direct to a specific product URL

          My question is what happens when a product which the googlbot is direct to, is out of stock but is still listed in the canonical tag ?

            If the canonical page disappears when it's out of stock, the user will get a 404 error when they try to access that URL. You'll need to canonicalize duplicates to a generic product or category page that won't disappear when the product is out of stock.  Furthermore, if a product goes out of stock and you'll have more in stock later, it's best (for SEO purposes) to leave the page with an "out of stock" notice rather than remove it completely from the website.

              I have a similar query. However in my case if the out of stock item is discontinued the page is removed but available product variations may remain.

              What happens in the case where my canonical is out of stock and the page removed but other product variations are available?

              Thanks,

                To my knowledge, the behavior of the googlebot is not influenced by whether or not the product is out of stock. Is the page still accessible when the product is out of stock, or does it not display at all?

                If the product page remains with an "out of stock" message, that's what users from search will see. If the product page becomes inaccessible when it goes out of stock temporarily, users from search will likely see a 404 page.

                You may want to canonicalize to a higher level category page rather than one of the product variation pages.  That way, it won't be an issue if one product variation goes out of stock.

                May I ask which ecommerce software you are using?

                  Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO.  It is coming up as an error in site crawls 'Pages with 404 errors'  Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag.  Seems a bit of a strange approach to me.

                  Duplicate Page Titles For Paginated Topics In Blog

                  Hello, I've just run a site audit and it has come up with a duplicate title tag issue for the topics section of our blog. For example it is flagging that the following have the same page title. https://blog.companyname.com/topic/topic-name https://blog.companyname.com/topic/topic-name/page/2 How significant is this as an SEO issue and what are the ways we can go about fixing this? I look forward to any suggestions and guidance that can be provided. Thanks, John

                  Duplicate content through product variants

                  Hi, Before you shout at me for not searching - I did and there are indeed lots of threads and articles on this problem. I therefore realise that this problem is not exactly new or unique. The situation: I am dealing with a website that has 1 to N (n being between 1 and 6 so far) variants of a product. There are no dropdown for variants. This is not technically possible short of a complete redesign which is not on the table right now. The product variants are also not linked to each other but share about 99% of content (obvious problem here). In the "search all" they show up individually. Each product-variant is a different page, unconnected in backend as well as frontend. The system is quite limited in what can be added and entered - I may have some opportunity to influence on smaller things such as enabling canonicals. In my opinion, the optimal choice would be to retain one page for each product, the base variant, and then add dropdowns to select extras/other variants. As that is not possible, I feel that the best solution is to canonicalise all versions to one version (either base variant or best-selling product?) and to offer customers a list at each product giving him a direct path to the other variants of the product. I'd be thankful for opinions, advice or showing completely new approaches I have not even thought of! Kind Regards, Nico

                  Removing a large number of unnecessary pages from a site

                  Hi all, I got a big problem with my website. I have a lot of page, duplicate page made from various combinations of selects, and for all this duplicate content we've be hit by a panda update 2 years ago. I don't want to bring new content an all of these pages, about 3.000.000, because most of them are unnecessary. Google indexed all of them (3.000.000), and I want to redirect the pages that I don't need anymore to the most important ones. My question, is there any problem in how google will see this change, because after this it will remain only 5000-6000 relevant pages?

                  Adding Rel Canonical to multiple pages

                  Hi, Our CMS generates a lot of duplicate content, (Different versions of every page for 3 different font sizes). There are many other reasons why we should drop this current CMS and go with something else, and we are in the process of doing that. But for now, does anyone know how would I do the following: I've created a spreadsheet that contains the following: Column 1: rel="canonical" tag for URL Column 2: Duplicate Content URL # 1 Column 3: Duplicate Content URL # 2 Column 4: Duplicate Content URL # 3 I want to add the tag from column 1 into the head of every page from column 2,3, and 4. What would be a fast way to do this considering that I have around 1800 rows. Check the screenshot of the builtwith.com result to see more information about the website if that helps. Farris bxySL

                  How to structure rel=canonical for a e commerce site

                  Hello, So I have searched the Q & A , Google, the zen cart forum and at this point I am looking for some one to give a concrete answer on what I should do.  There is a lot of different opinions on " rel=canonical" and how to apply it , since there are many other variable in place. I have a zen cart site.  I am using the latest 1.3.9 version.  The default setting ( seem to me) uses the  rel=canonical to point back to the specific link product or category respectively. Most of the time I have two scenarios. 1. Main category --->  Sub category----> Product 2. Main Category----> Product I'll give an example http://www.perfectindesign.com/awards ---main category http://www.perfectindesign.com/awards/acrylic-awards sub category http://www.perfectindesign.com/awards/acrylic-awards/slanted-award  product (this example has three sub categories with maybe 12 products in one 4 in the second and 5 in the third) From looking at the source code for each url it the rel=canonical just points back to its own url. I want to avoid competing against my self, for the example above keyword "acrylic awards" so should the use of the re=canonical be changes site wide to have products point back to sub categories when they exist and have products point back to main categories when no sub categories exist? I am very new to seo, specifically eCommerce seo.   If you have experience and have done this to a site you manage for a client or your own please advise how to proceed. Also if I'm missing some thing that will give me a better understanding of the bigger seo picture that would be great. Thanks, Yevgeny
