      Does anyone know how to add canonical tags to product pages in Opencart?

      Is this possible to do in htaccess? If so, how specifically should it be written in?

      Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

        Apparently this didn't work. According to the Moz tool I have the same amount of duplicate title tags as before.

          I suggerst you to adopt the following :

          The best way to achieve this is to modify your Document class, set your canonical in your controller, then render it in the header controller.

          Edit system/library/document.php

          add:

          private $canonical; to your class variables up top.

          Then add the following methods:

          <code>publicfunction setCanonical($url){ $this->canonical = $url;}publicfunction getCanonical(){return $this->canonical;}</code>
          

          In your header controller add:

          $this->data['canonical'] = $this->document->getCanonical();

          Then you can set your canonical dynamically in the header controller:

          <code>if(isset($this->request->get['_route_'])): $canonical_route = $this->request->get['_route_'];else: $canonical_route =''; endif; $this->document->setCanonical($this->data['base']. $canonical_route);</code>
          

          Or you can set it manually in your controllers using the setCanonical method.

              Move to new domain using Canonical Tag

              At the moment, I am moving from olddomain.com (niche site) to the newdomain.com (multi-niche site). Due to some reasons, I do not want to use 301 right now and planning to use the canonical pointing to the new domain instead. Would Google rank the new site instead of the old site? From what I have learnt, the canonical tag lets Google know that which is the main source of the contents. Thank you very much!

              Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?

              We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

              Shopify Product Variants vs Separate Product Pages

              Let's say I have 10 different models of hats, and each hat has 5 colors. I have two routes I could take: a) Make 50 separate product pages Pros: -Better usability for customer because they can shop for just masks of a specific color. We can sort our collections to only show our red hats. -Help SEO with specific kw title pages (red boston bruins hat vs boston bruins hat). Cons: -Duplicate Content: Hat model in one color will have almost identical description as the same hat in a different color (from a usability and consistency standpoint, we'd want to leave descriptions the same for identical products, switching out only the color) b) Have 10 products listed, each with 5 color variants Pros: -More elegant and organized -NO duplicate Content Cons: -Losing out on color specific search terms -Customer might look at our 'red hats' collection, but shopify will only show the 'default' image of the hat, which could be another color. That's not ideal for usability/conversions. Not sure which route to take. I'm sure other vendors must have faced this issue before. What are your thoughts?

              Wildcard Redirects & Canonical Tags

              I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
              www.domain.com/red-widgets-cid-1234-1.html
              www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:
              www.domain.com/red-widgets-cid-1234.html New URL:
              www.domain.com/red-widgets-cid-4567.html Current URLs Example2: www.domain.com/red-widgets-cid-1234+10.html
              www.domain.com/red-widgets-cid-1234+10-1.html
              www.domain.com/red-widgets-cid-1234+10-1-1.html Canonical on All Above URLs:
              www.domain.com/red-widgets-cid-1234+10.html New URL:
              www.domain.com/red-widgets-cid-6789.html Current URLs Example3: www.domain.com/red-widgets-cid-1234+10+5.html
              www.domain.com/red-widgets-cid-1234+10+5-1.html
              www.domain.com/red-widgets-cid-1234+10+5-1-1.html Canonical on All Above URLs:
              www.domain.com/red-widgets-cid-1234+10+5.html New URL:
              www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs.  However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?

              H2 Tag Backlink - is this safe?

              I have found that my site is getting a link from a good site, but my concern is that the link is in a H2 tag in the footer of the front page of the site Would getting a link from a site wrapped in H2 tags be safe? The anchor is my sites brand name

              Product URL structure for a marketplace model

              Hello All. I run an online marketplace start-up that has around 10000 products listed from around 1000+ sellers. We are a similar model to etsy/ebay in the sense that we provide a platform but sellers to list products and sell them. I have a URL structure question. I have read http://www.seomoz.org/q/how-to-define-best-url-structure-for-product-pages which seems to show everyone suggests to use Products: products/category/product-name Categories: products/category as the structure for product pages. Because we are a marketplace (our category structure has multiple tiers sometimes up to 3) our sellers choose a category for products to go in. How we have handled this before is we have used: Products: products/last-tier-category-chosen/product-name (eg: /products/sweets-and-snacks/fluffy-marshmallows) Categories: products/category (eg: /products/sweets-and-snacks) However we have two issues with this: The categories can sometimes change, or users can change them which means the links completely change and undo any link building work built up. The urls can get a bit long and am worried that the most important data (the fluffy marshmallow that reflects in the page title and content) is left till too late in the URL. As a result we plan to change our URL structure (we are going through a rebuild anyhow so losing old links is not an issue here) so that the new structure was: Products: products/product-name(eg: /products/fluffy-marshmallows) Categories: products/category (eg: /products/sweets-and-snacks) My concern about doing this however, and question here, is whether this willnegatively impact the "structure" of pages when google crawls our marketplace.Because "fluffy marshmallows" will no longer technically fit into the url structure of "sweets and snacks". I dont know if this would have a negative impact or not. FYI etsy (one of the largest marketplace models in the world) us the latter approach and do not have categories in product urls, eg: listing/42003836/vintage-french-industrial-inspired-side Any ideas on this? Many thanks!

              How to properly link to products from category pages?

              Hi All, We have an e-commerce website and the category pages are built so that there is a product image and below it there is the title. Both the image and the title are in a href (each on its own). I encountered the following unfinished discussion here at MOZ:
              http://www.seomoz.org/q/how-to-optimize-achor-text-links-on-ecommerce-category-page#post-93758 The discussion states that its improper. The question is - if it is wrong then why? (maybe because Google will give its weight to the image anchor instead of the text anchor since it is higher in the page). The other question is how to resolve the matter?
              Should I add nofollow to the image href? Thanks

              Canonical & noindex? Use together

              For duplicate pages created by the "print" function, seomoz says its better to use noindex (http://www.seomoz.org/blog/complete-guide-to-rel-canonical-how-to-and-why-not) and JohnMu says its better to use canonical http://www.google.com/support/forum/p/Webmasters/thread?tid=6c18b666a552585d&hl=en What do you think?
