Canonical Confusion
-
So I have products appearing in several categories, all of which have the correct canonical url. But Moz is flagging up pages I never knew existed, and I don't understand why they exist at all and more so why my canonical fix isn't occurring for them, as below:
SEO Friendly URL: http://thespacecollective.com/nasa-pin-sets/nasa-shuttle-mission-pin-set-no2
Weird URL to same product: http://thespacecollective.com/index.php?route=themecontrol/product&product_id=159
Is this a developer problem rather than an SEO problem?

I understand , you may need an opencart professional to fix the problem.

Hello Vijay,
As discussed previously I already use an extension and the problem is still occurring. I was hopeful with the solution in your 2nd link, tried it, and as with most things gave me an error and took down my site. I'm sure this error is a problem that a good developer could fix but alas I don't have one.

THIs is the common issue with all open cart sites, if you discuss this issue with the developer, he will be able to fix it… no big deal!

Hi spacecollective,
Firstly, I love the site and I'll be buying a gift for my dad's birthday from here!
There are definitely some issues with canonical tag and redirect chains here. I'd say it's an issue with the development of the site that is now causing SEO issues - so it's an issue for both!
I'll use the product you mentioned in my example:
http://thespacecollective.com/index.php?route=themecontrol/product&product_id=159
canonicalizes to
http://thespacecollective.com/nasa-shuttle-mission-pin-set-no2/
which redirects to
http://thespacecollective.com/nasa-pin-sets/nasa-shuttle-mission-pin-set-no2
which canonicalizes to
http://thespacecollective.com/space-memorabilia/nasa-pin-sets/nasa-shuttle-mission-pin-set-no2/All of these URLs should have the same canonical URL. I always prefer to canonicalize products that appear under multiple categories to the root level (it's also what Magento does by default and it works very well).
So, in this example, all variations would have a canonical tag pointing to
http://thespacecollective.com/nasa-shuttle-mission-pin-set-no2/However, in your OpenCart CMS, it may be easier to canonicalize these to the final URL in the chain (http://thespacecollective.com/space-memorabilia/nasa-pin-sets/nasa-shuttle-mission-pin-set-no2/) as this is also the URL that is listed in the XML sitemap.
If you choose to canonicalize to the root level, you will need to make sure that the sitemap is updated to only include this new canonical URLs.
Hope this helps. Feel free to send me a PM if you have any further questions
Cheers,
David

Hi There,
I checked your website, it uses Opencart as a platform for e-commerce. You can search and use an extension from here http://www.opencart.com/index.php?route=extension/extension&filter_search=product canonical url seo
Or this can help you through https://isenselabs.com/posts/how-to-solve-the-duplicate-content-issue-in-opencart
I hope this helps, please feel free to ask further questions.
Regards,
Vijay

Canonical and Alternate Advice
At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?

Google Ignoring Canonical Tag for Hundreds of Sites
Bazaar Voice provides a pretty easy-to-use product review solution for websites (especially sites on Magento): https://www.magentocommerce.com/magento-connect/bazaarvoice-conversations-1.html If your product has over a certain number of reviews/questions, the plugin cuts off the number of reviews/questions that appear on the page. To see the reviews/questions that are cut off, you have to click the plugin's next or back function. The next/back buttons' URLs have a parameter of "bvstate....." I have noticed Google is indexing this "bvstate..." URL for hundreds of sites, even with the proper rel canonical tag in place. Here is an example with Microsoft: http://webcache.googleusercontent.com/search?q=cache:zcxT7MRHHREJ:www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Book/productID.325716000%3Fbvstate%3Dpg:8/ct:r+&cd=2&hl=en&ct=clnk&gl=us My website is seeing hundreds of these "bvstate" urls being indexed even though we have a proper rel canonical tag in place. It seems that Google is ignoring the canonical tag. In Webmaster Console, the main source of my duplicate titles/metas in the HTML improvements section is the "bvstate" URLs. I don't necessarily want to block "bvstate" in the robots.txt as it will prohibit Google from seeing the reviews that were cutoff. Same response for prohibiting Google from crawling "bvstate" in Paramters section of Webmaster Console. Should I just keep my fingers crossed that Google honors the rel canonical tag? Home Depot is another site that has this same issue: http://webcache.googleusercontent.com/search?q=cache:k0MBLFcu2PoJ:www.homedepot.com/p/DUROCK-Next-Gen-1-2-in-x-3-ft-x-5-ft-Cement-Board-172965/202263276%23!bvstate%3Dct:r/pg:2/st:p/id:202263276+&cd=1&hl=en&ct=clnk&gl=us

Dealing with Canonical tag in volusion
Hi We have an ecommerce site where we have some returns/scratch /dented products identical to the original one. The onpage content of the damaged/original is pretty much identical with the damaged just having a describing the damage. I had wanted to make a canonical tag on the damaged product to the original so it would not be a problem of duplicate content but as it is a volusion site we dont have that option - it only canonicalizes back to itself! Any ideas what else I can do - cant really change the content much and I dont really want to deindex it so people find it? Thanks!

Dealing with non-canonical http vs https?
We're working on a complete rebuild of a client's site. The existing version of the site is in WordPress and I've noticed that the site is accessible via http and https. The new version of the site will have mostly or entirely different URLs. It seems that both http and https versions of a page will resolve, but all of the rel-canonical tags I've seen point to the https version. Sometimes image tags and stylesheets are https, sometimes they aren't. There are both http and https pages in Google's index. Having looked at other community posts about http/https, I've gathered the following: http/https is like two different domains. http and https versions need to be verified in Google Webmaster Tools separately. Set up the preferred domain properly. Rel-canonicals and internal links should have matching protocols. My thought is that we will do a .htaccess that redirects old URLs regardless of the protocol to new pages at one protocol. I would probably let the .css and image files from the current site 404. When we develop and launch the new site, does it make sense for everything to be forced to https? Are there any particular SEO issues that I should be aware of for a scenario like this? Thanks!

Do I need to use canonical tags if I'm 301 redirecting pages?
I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/
Intermediate & Advanced SEO | | Omnipress
http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx (I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!0 -
Is there a reason to put a canonical to yourself? Interesting case...
Hi, I was looking at BlueNile (biggest diamonds online dealer in the world) since I was wondering how they dealt with similar products and with sold products. Each diamond that is sold is unique. Once it is sold it is unavailable for sale. Also, all diamonds are VERY similar so they should also find a way to handle duplication in content. Look at the following 2 pages: http://www.bluenile.com/round-diamond-1-carat-or-less-ideal-cut-g-color-vs1-clarity_LD02360835 http://www.bluenile.com/round-diamond-1-carat-or-less-ideal-cut-g-color-vs1-clarity_LD02366155 The pages are practically identical and in the "view source" I noticed that they add a canonical tag to themselves... Any thoughts on that? Thanks

Canonical tag question
Suppose a site has two pages ( Page A ) and Page B. Both of them have pagerank, but duplicate content. The page A is ranked for keyword "seo india" and page B is ranked for keyword "seo services". If i implement canonical tag on page B, does 1. The pagerank of page B will be transfered to Page A ? 2. Does the site A now ranks for keyword "seo servicies " ( for which Page B was ranking earlier )
