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

Why isn't the canonical tag on my client's Magento site working?
The reason for this mights be obvious to the right observer, but somehow I'm not able to spot the reason why. The situation:
Intermediate & Advanced SEO | | Inevo
I'm doing an SEO-audit for a client. When I'm checking if the rel=canonical tag is in place correctly, it seems like it: view-source:http://quickplay.no/fotball-mal.html?limit=15) (line nr 15) Anyone seing something wrong with this canonical? When I perform a site:http://quickplay.no/ search, I find that there's many url's indexed that ought to have been picked up by the canonical-tag: (see picture) ..this for example view-source:http://quickplay.no/fotball-mal.html?limit=15 I really can't see why this page is getting indexed, when the canonical-tag is in place. Anybody who can? Sincerely 🙂 GMdWg0K0 -
Use Canonical or Robots.txt for Map View URL without Backlink Potential
I have a Page X with lots of unique content. This page has a "Map view" option, which displays some of the info from Page X, but a lot is ommitted.

Multiply domains and duplicate content confusion
I've just found out that a client has multiple domains which are being indexed by google and so leading me to worry that they will be penalised for duplicate content. Wondered if anyone could confirm a) are we likely to be penalised? and b) what should we do about it? (i'm thinking just 301 redirect each domain to the main www.clientdomain.com...?). Actual domain = www.clientdomain.com But these also exist: www.hostmastr.clientdomain.com www.pop.clientdomain.com www.subscribers.clientdomain.com www.www2.clientdomain.com www.wwwww.clientdomain.com ps I have NO idea how/why all these domains exist I really appreciate any expertise on this issue, many thanks!

Canonical tag
Hi all, I have an ecommerce client and on the pages they have a drop down so customers can view via price, list etc. Natrurally I want a canonical tag on these pages, here's the question. as they have different pages of products, the canonical tag on http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7/?sort=price_asc,searchterm=,layout=grid,page=1 is to http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7. now, because the page=7 is a duplicate of the main page, shouldn't the canonical just be to the main page rather than page=7? Even when there is a canonical tag on the /Christmas/page=7 to the /Christmas page? hope that makes sense to everyone!

I get warnings for overly dynamic urls, but have canonical links in place.
Hi, Seomoz gives me warnings for overly dynamic urls. This is mostly caused by a crumbtrail system. I have a canonical link in the header for all the urls I receive warnings on, should I still worry about this? Thanks!

HTTP Header Canonical Tags
I want to be able to add canonical tags to http headers of individual URL's using .htacess, but I can't find any examples for how to do this. The only example I found was when specifying a file: http://www.seomoz.org/blog/how-to-advanced-relcanonical-http-headers N.B. It's not possible to add regular canonical tags to the of my pages as they're dynamically generated. I was trying to add the following to the .htaccess in order to add a canonical tag in the header of the page http://frugal-father.com/is-finance-in-the-uk-too-london-centric/, but I've checked with Live HTTP headers and the canonical line isn't showing : <files "is-finance-in-the-uk-too-london-centric="" "="">Header add Link "<http: frugal-father.com="">; rel="canonical"'</http:></files> Any ideas?

Use of rel=canonical to view all page & No follow links
Hey, I have a couple of questions regarding e-commerce category pages and filtering options: I would like to implement the rel=canonical to the view all page as suggested on this article on googlewebmastercentral. If you go on one of my category pages you will see that both the "next page link" and the "view all" links are nofollowed. Is that a mistake? How does nofoolow combines with canonical view all? Is it a good thing to nofollow the "sorty by" pages or should I also use Noindex for them?

Category Pages - Canonical, Robots.txt, Changing Page Attributes
A site has category pages as such: www.domain.com/category.html, www.domain.com/category-page2.html, etc... This is producing duplicate meta descriptions (page titles have page numbers in them so they are not duplicate). Below are the options that we've been thinking about: a. Keep meta descriptions the same except for adding a page number (this would keep internal juice flowing to products that are listed on subsequent pages). All pages have unique product listings. b. Use canonical tags on subsequent pages and point them back to the main category page. c. Robots.txt on subsequent pages. d. ? Options b and c will orphan or french fry some of our product pages. Any help on this would be much appreciated. Thank you.
