          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?

                  Duplicate content, although page has "noindex"

                  duplicate content

                  Hello, I had an issue with some pages being listed as duplicate content in my weekly Moz report. I've since discussed it with my web dev team and we decided to stop the pages from being crawled. The web dev team added this coding to the pages <meta name='robots' content='max-image-preview:large, noindex dofollow' />, but the Moz report is still reporting the pages as duplicate content. Note from the developer "So as far as I can see we've added robots to prevent the issue but maybe there is some subtle change that's needed here. You could check in Google Search Console to see how its seeing this content or you could ask Moz why they are still reporting this and see if we've missed something?" Any help much appreciated!

                  Duplicate Content Issues on Product Pages

                  Hi guys Just keen to gauge your opinion on a quandary that has been bugging me for a while now. I work on an ecommerce website that sells around 20,000 products. A lot of the product SKUs are exactly the same in terms of how they work and what they offer the customer. Often it is 1 variable that changes. For example, the product may be available in 200 different sizes and 2 colours (therefore 400 SKUs available to purchase). Theese SKUs have been uploaded to the website as individual entires so that the customer can purchase them, with the only difference between the listings likely to be key signifiers such as colour, size, price, part number etc. Moz has flagged these pages up as duplicate content. Now I have worked on websites long enough now to know that duplicate content is never good from an SEO perspective, but I am struggling to work out an effective way in which I can display such a large number of almost identical products without falling foul of the duplicate content issue. If you wouldnt mind sharing any ideas or approaches that have been taken by you guys that would be great!

                  How to create site map for large site (ecommerce type) that has 1000's if not 100,000 of pages.

                  I know this is kind of a newbie question but I am having an amazing amount of trouble creating a sitemap for our site Bestride.com.  We just did a complete redesign (look and feel, functionality, the works) and now I am trying to create a site map.  Most of the generators I have used "break" after reaching some number of pages.  I am at a loss as to how to create the sitemap.  Any help would be greatly appreciated! Thanks

                  Volusion eCommerce Site 302s and Canonicalization

                  There have been a couple other threads concerning this topic so I apologize, but I have an iteration on the main question that has not been answered. Crawl Diagnostics is giving me a bunch of 302 temporary redirect notices. For example, here is a page title URL:
                  http://store.in-situ.com/Rugged-Conductivity-Meter-p/0073380.htm and here is the redirect:
                  http://store.in-situ.com/Rugged-Conductivity-Meter-p/tape-clt-meter.htm?1=1&CartID=0 The first link is actually a child product of:
                  http://store.in-situ.com//Rugged-Conductivity-Meter-p/tape-clt-meter.htm Volusion tech support told me they believe most of them are meta redirects but could not find any documentation on them. All the other threads concerning this have said to either change the 302s to 301s, which I don't think is possible, or to add a nofollow tag. My question is do I need to do anything if both those pages are canonical to the parent product? Should I be passing on the linkjuice if neither of those pages are of high value?

                  How to prevent duplicate content at a calendar page

                  Hi, I've a calender page which changes every day. The main url is
                  /calendar For every day, there is another url: /calendar/2012/09/12
                  /calendar/2012/09/13
                  /calendar/2012/09/14 So, if the 13th september arrives, the content of the page 
                  /calendar/2012/09/13
                  will be shown at
                  /calendar So, it's duplicate content. What to do in this situation? a) Redirect from /calendar to /calendar/2012/09/13 with 301? (but the redirect changes the day after to  /calendar/2012/09/14) b) Redirect from /calendar to /calendar/2012/09/13 with 302 (but I will loose the link juice of /calendar?) c) Add a canonical tag at /calendar (which leads to /calendar/2012/09/13) - but I will loose the power of /calendar (?) - and it will change every day... Any ideas or other suggestions? Best wishes, Georg.

                  Hreflang on non-canonical pages

                  Hi! I've been trying to figure out what is the best way to solve this dilemma with duplicate content and multiple languages across domains. 1 product info page 2 same product but GREEN
                  3 same product but RED
                  4 same product but YELLOW **Question: ** Since pages 2,3,4 just varies slightly I use the canonical tag to indicate they are duplicates of page 1. Now I also want to indicate there are other language versions with the_ rel="alternate" hreflang="x" _element. Should I place the _rel="alternate" hreflang="x" _on the canonical page only pointing to the canonical page with "x" language. Should I place the _rel="alternate" hreflang="x" _on all pages pointing to the canonical page with the "x" language? Should I place the _rel="alternate" hreflang="x"  _on all pages and then point it to the translated page (even if it is not a canonical page) ? /Lars

                  Google counting numbers of products on category pages - what about pagination ?

                  Hi there, Whilst checking out the SERPS, as you do, I noticed that where our category page appears, google now seems to be counting the number of products (what it calls items) on the product page and displaying this in the 1st part of the description (see image attached). My problem is we employ pagination, so that our category page will have 15 items on it, then there are paginated results for the rest, with either ?page=2 or page-2/ etc. appended to the URL. Although this is only a minor issue, I was just wondering if there was a way to change the number of products displayed on that page to be the entire number of products in that category, is there a microformat markup or something that can over-ride what google has detected ? Furthermore is this system of pagination effective ? I have considered using javascript pagination, such that all products would be loaded on to the one page but hidden until 'paginated', but I was worried about having hidden elements on the page, and also the impact of load times. Although I think this may solve the problem and display the true number of products in a section! Any help much appreciated, Stuart b4urme.jpg
