Canonical for duplicate pages in ecommerce site and the product out of stock
-
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 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

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

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

Same Video on Multiple Pages and Sites... Duplicate Issues?
We're rolling out quite a bit of pro video and hosting on a 3-party platform/player (likely BrightCove) that also allows us to have the URL reside on our domain. Here is a scenario for a particular video asset: A. It's on a product page that the video is relevant for. B. We have an entry on our blog with the video C. We have a separate section of our site "Video Library" that provides a centralized view of all videos. It's there too. D. We eventually give the video to other sites (bloggers, industry educational sites etc) for outreach and link-building. A through C on our domain are all for user experience as every page is very relevant, but are there any duplicate video issues here? We would likely only have the transcript on the product page (though we're open to suggestions). Any related feedback would be appreciated. We want to make this scalable and done properly from the beginning (will be rolling out 1000+ videos in 2010)

Duplicate canonical URLs in WordPress
Hi everyone, I'm driving myself insane trying to figure this one out and am hoping someone has more technical chops than I do. Here's the situation... I'm getting duplicate canonical tags on my pages and posts, one is inside of the WordPress SEO (plugin) commented section, and the other is elsewhere in the header. I am running the latest version of WordPress 3.1.3 and the Genesis framework. After doing some testing and adding the following filters to my functions.php: <code>remove_action('wp_head', 'genesis_canonical'); remove_action('wp_head', 'rel_canonical');</code> ... what I get is this: With the plugin active + NO "remove action" - duplicate canonical tags

With the plugin disabled + NO "remove action" - a single canonical tag
With the plugin disabled + A "remove action" - no canonical tag I have tried using only one of these remove_actions at a time, and then combining them both. Regardless, as long as I have the plugin active I get duplicate canonical tags. Is this a bug in the plugin, perhaps somehow enabling the canonical functionality of WordPress? Thanks for your help everyone. Robert Dempsey0 -
Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
