Ecommerce Link Juice and Canonical URLs
-
Hello all. I am optimising an E-Commerce site and I have a questions about Products in several categories & Canonical URL's. Using Magento Platform.
site.com/category1/product1/ ( link from category is site.com/product1/ )
site.com/category2/product1/ ( link from category is site.com/product1/ )
site.com/category2/subcategory1/product1 ( link from category is the same , as is the canonical URL )
site.com/product1/ ( this is where other categories link to )Canonical links for all the above is site.com/category2/subcategory1/product1 which takes care of duplicate content correctly.
I just wonder if we would get more link juice if ALL the links from all categories went to site.com/category2/subcategory1/product1 ( instead of some going to site.com/product1/ )
Thanks in advance

Thank you for confirming my thoughts. In the meantime, that's exactly what we've implemented anyway
It didn't seem logical to me either - nice to have a sounding board over here.

Why would you canonically link Product pages to the category page? Of course that is going to disappear the product pages. Why not just link from the product pages to category pages with a normal link <a>to increase page authority on the category page?</a>

Hey Guys
I'm sure I stumbled across a Q&A about canonically linking product pages to appropriate category pages, the theory being that 25 product pages canonically linking to the relevant category page should increase the authority of the category page. By extension, that means that product pages never show up in SERPS, which I'm not quite so keen on.
I'll be damned if I can find the thread, even with a search engine
Any advice or tales of woe gratefully received.

I completely agree. 1 URL is by far the better choice.
-
I still think the better option is to have 1 URL. I was using the root URL for products ( effectively 1 URL ) and not having the category in the URL and my SEO was doing well - BUT I wanted the Categories to be displayed in Google as clickable - so I changed to the canonical method having different URLs with 1 Canonical. Over a couple of months my SEO suffered terribly - some categories in the top 10 down to 20-30 . I have just implemented having 1 URL ( with category in it ) - we will see how we go..

Hello Yusuf,
If you have a link to Jon Mueller saying that, instead of someone else saying he did, I would love to go check it out because the statement is in direct opposition to the one on Google's website here, which says:
"Consolidating link signals for the duplicate or similar content. It helps search engines to be able to consolidate the information they have for the individual URLs (such as links to them) on a single, preferred URL. This means that links from other sites to
http://example.com/dresses/cocktail?gclid=ABCD
get consolidated with links tohttp://www.example.com/dresses/green/greendress.html
."Notice is says "helps" though. As always, the directive is a "hint" to Google, which has the right to ignore the hint if they want to.

Thanks - yes I am actually seeing this first hand.
I used the canonical method - and it is rapidly degrading my SEO . not hugely , but some things that were almost on page 1 are now at the end of page 1 / beginning of page 2. I am currently changing everything to have 1 URL ( with the category this time )

Hi Everett,
Thanks for your response.
I also believed that the rel=canonical merge the link profiles but so far all the evidence I've seen suggests that it doesn't.
Firstly - Jon Mueller from Google stated that the rel=canonical tag doesn't merge the link profile. That's talked about here.
http://moz.com/community/q/quick-rel-canonical-link-juice-question
Secondly, if I look at some examples, you'd expect pages with rel=canonical tags to have zero authority etc. reported for page alternatives in Open Site Explorer.
e.g. on the ASOS website there is a link to the men's section which uses a query string parameter.
http://www.asos.com/men/?via=top
The canonical url is
Both report different levels of authority. If the link profiles were merged, would you not expect either the same levels of authority reported or the non-canonical version to report no authority?
I understand that Moz tools don't work like Google so I'd like to hear from someone who can explain this.
Thanks,
Yusuf

Yusuf,
I do believe rel canonical tags merge the link profile of all non-canonical URLs to the one canonical URL.
Also, relying on redirects in this case could be problematic for breadcrumbs.

Hello Marty,
If you have the opportunity to use only ONE URL, to which you will link from all categories - and which will be the one and only canonical for that product - I would use site.com/product/product1. Note the use of a /product/ directory instead of being off the root. I find that having products in a product directory makes diagnoses of issues (i.e. index count, site:domain.com inurl:product searches, Analytics segmentation...) a lot easier. However, if you want to keep it site.com/product1 then that would be fine as well. It would be preferable to using multiple URLs and relying on 301 redirects or rel canonicals, which are effective band-aids, but band-aids nevertheless. It is better to actually fix the problem, which is products living on multiple URLs.
Of course you're going to still want to either 301 redirect or rel canonical the old ones to your canonical version since the URLs are likely already in Google's system and possibly have external links.
And you should think about what happens to breadcrumbs as well. If a user gets to /product1 from one category vs another, will their breadcrumb change and how will that be done? Is it ok for usability for the breadcrumb on that product page to always reference the canonical category (i.e. Home ---> category 2 ---> category2 ---> product1)? I tend to think so, and this also may help your internal linking be more consistent when Googlebot visits the page.

Thanks for your replys
- I'm not really asking the question whether it should be a 301 or Canonical - I have the opportunity to make all the links go directly to the correct URL - or to go to the category and use Canonical. ( then there would ony be one actual URL ) - just wondering if that is more beneficial as you would have 4-5 links going to the same product page instead of 1 going to the product page and the rest with Canonical URL's .
So if you have any more ideas...???
-
The canonical is the right way of setting the website up. When we take on an E-commerce client that has products accessible via multiple URL's is to Google which one has the authority, so if you are looking at product X then google it and see which URL Google is giving the authority to, look at the path then canonical all other variations to that path.

Hi
I've often wondered about this - whether to use a 301 or leave pages as they are and use the rel=canonical tag.
I would think that a 301 from the duplicate to preferred page would be best. This would mean that any inbound links will pass juice to the preferred page (i.e. site.com/category2/subcategory1/product1). The rel=canonical tag, as far as I know, does not merge the link profile of the duplicate pages.
However, depending on the skill of your developers, other rewrite/redirect rules on your site and your CMS - the rel=canonical might be the only feasible method.
This page explains it very nicely.

Index, follow on a paginated page with a different rel=canonical URL
Hello, I have a question about meta robots ="index, follow" and rel=canonical on category page pagination. Should the sorted page be <meta name="robots" content="index,follow"></meta name="robots" content="index,follow"> since the rel="canonical" is pointing to a separate page that is different from the URL? Any thoughts on this topic would be awesome. Thanks. Main Category Page

I have a lot of spammy links coming to my 404 page (the URLs have been removed now). Should i re-direct to Home?
I have a lot of spammy links pointing at my website according to MOZ. Thankfully all of them were for some URLs that we've long since removed so they're hitting my 404. Should i change the 404 with a 301 and Re-Direct that Juice to my home page or some other page or will that hurt my ranking?

Should we use URL parameters or plain URL's=
Hi, Me and the development team are having a heated discussion about one of the more important thing in life, i.e. URL structures on our site. Let's say we are creating a AirBNB clone, and we want to be found when people search for apartments new york. As we have both have houses and apartments in all cities in the U.S it would make sense for our url to at least include these, so clone.com/Appartments/New-York but the user are also able to filter on price and size. This isn't really relevant for google, and we all agree on clone.com/Apartments/New-York should be canonical for all apartment/New York searches. But how should the url look like for people having a price for max 300$ and 100 sqft? clone.com/Apartments/New-York?price=30&size=100 or (We are using Node.js so no problem) clone.com/Apartments/New-York/Price/30/Size/100 The developers hate url parameters with a vengeance, and think the last version is the preferable one and most user readable, and says that as long we use canonical on everything to clone.com/Apartments/New-York it won't matter for god old google. I think the url parameters are the way to go for two reasons. One is that google might by themselves figure out that the price parameter doesn't matter (https://support.google.com/webmasters/answer/1235687?hl=en) and also it is possible in webmaster tools to actually tell google that you shouldn't worry about a parameter. We have agreed to disagree on this point, and let the wisdom of Moz decide what we ought to do. What do you all think?

A sneaky site? Two URLs with a similar layout linking back and forth.
Hello. I have a competitor that is on the front page of Google (and often at or near the top) for many desirable keywords - almost unbelievably so. I notice that their site has a blog. When I click the blog button, I am taken to a different URL that has a very similar layout with a similar navigation bar, etc. When I click one of the navigation buttons on the blog site, I am taken back to the other URL. This seems strange. Is there some ranking benefit to having two URLs set up like this? Is this a sneaky site? Thank you!

To "Rel canon" or not to "Rel canon" that is the question
Looking for some input on a SEO situation that I'm struggling with. I guess you could say it's a usability vs Google situation. The situation is as follows: On a specific shop (lets say it's selling t-shirts). The products are sorted as follows each t-shit have a master and x number of variants (a color). we have a product listing in this listing all the different colors (variants) are shown. When you click one of the t-shirts (eg: blue) you get redirected to the product master, where some code on the page tells the master that it should change the color selectors to the blue color. This information the page gets from a query string in the URL. Now I could let Google index each URL for each color, and sort it out that way. except for the fact that the text doesn't change at all. Only thing that changes is the product image and that is changed with ajax in such a way that Google, most likely, won't notice that fact. ergo producing "duplicate content" problems. Ok! So I could sort this problem with a "rel canon" but then we are in a situation where the only thing that tells Google that we are talking about a blue t-shirt is the link to the master from the product listing. We end up in a situation where the master is the only one getting indexed, not a problem except for when people come from google directly to the product, I have no way of telling what color the costumer is looking for and hence won't know what image to serve her. Now I could tell my client that they have to write a unique text for each varient but with 100 of thousands of variant combinations this is not realistic ir a real good solution. I kinda need a new idea, any input idea or brain wave would be very welcome. 🙂

Redirect between domains: any real number on how much link juice is lost?
Hi, I'm thinking of rebranding my website and moving it to a new domain. Of course I would implement 301 redirects page to page from old-domain.com to new-domain.com. I wonder if you have any real figure based on your experiments on how much link juice I could lose in the process and if it will take time for Google to re-crawl correctly the new page. I could get some of the backlinks changed as well, so they would point to the new domain. Cutts says it would get changed at least the more important, but how many? which are the more important? Also, what about if I move just a part of the website that has no backlinks? Supposedly it won't have any link juice to pass through but of course all the pages will be hosted on a brand new domain that won't pass domain-power to those internal pages, so will I lose rankings for these pages? Thanks for any help, Best regards
