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?

Rel=Canonical For Landing Pages
We have PPC landing pages that are also ranking in organic search. We've decided to create new landing pages that have been improved to rank better in natural search. The PPC team however wants to use their original landing pages so we are unable to 301 these pages to the new pages being created. We need to block the old PPC pages from search. Any idea if we can use rel=canonical? The difference between old PPC page and new landing page is much more content to support keyword targeting and provide value to users. Google says it's OK to use rel=canonical if pages are similar but not sure if this applies to us. The old PPC pages have 1 paragraph of content followed by featured products for sale. The new pages have 4-5 paragraphs of content and many more products for sale. The other option would be to add meta noindex to the old PPC landing pages. Curious as to what you guys think. Thanks.

Duplicate title-tags with pagination and canonical
Some time back we implemented the Google recommendation for pagination (the rel="next/prev"). GWMT now reports 17K pages with duplicate title-tags (we have about 1,1m products on our site and about 50m pages indexed in Google) As an example we have properties listed in various states and the category title would be "Properties for Sale in [state-name]". A paginated search page or browsing a category (see also http://searchengineland.com/implementing-pagination-attributes-correctly-for-google-114970) would then include the following: The title for each page is the same - so to avoid the duplicate title-tags issue, I would think one would have the following options: Ignore what Google says Change the canonical to http://www.site.com/property/state.html (which would then only show the first XX results) Append a page number to the title "Properties for Sale in [state-name] | Page XX" Have all paginated pages use noindex,follow - this would then result in no category page being indexed Would you have the canonical point to the individual paginated page or the base page?

How to prevent duplicate content at a calendar page
Hi, I've a calender page which changes every day. The main url is
Technical SEO | | GeorgFranz
/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.0 -
Two different canonical tags on one page
Due to an error, some of my pages now have two canonical tags on them. One is correct and the other goes to a nonsense URL (404 page). I know I should ideally remove the incorrect ones, but it's a big manual job. Are they doing any harm? Can I just leave them there and let Google figure it out? The correct ones are higher up in the code. Will this make a difference? Any help appreciated.

ECommerce: Best Practice for expired product pages
I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

What is the best URL designed for a product page?
Should a product page URL include the category name and subcategory name in it? Most ecommerce platforms it seems are designed to do have the category and sub-category names included in the URL followed by the product name. If that is the case and the same product is listed in more then 1 category and sub-category then will that product have 2 unique urls and as a result be treated as 2 different product pages by google? And then since it is the same product in two places on the site won't google treat those 2 pages as having duplicate content? SO is it best to not have the category and sub-category names in the URL of a product page? And lastly, is there a preferred character limit for a URL to be less than in size? 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

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.
