      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.

              Should I add no-follow tags to my widget links?

              Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

              Adding a Canonical Tag to each page referencing itself?

              Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self.  I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

              Canonical tag + HREFLANG vs NOINDEX: Redundant?

              Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

              Lowercase VS. Uppercase Canonical tags?

              Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase.  Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue?  Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's?  I'm not too well versed in canonical tags and would love a little insight. Thanks!

              Google and Product Description Tabs

              How does Google process a product page with description tabs?  For example, lets say the product page has a tab for Overview, Specifications, What's In the Box and so on. Wouldn't that content be better served in one main product description tab with the tab names used as (htags) or highlighted paragraph separators? Or, does all that content get crawled as a single page regardless of the tabs?

              How does a canonical work and is it necessary to also have a no index, follow tag in place?

              Across our site, we have canonical tags in place for URLs that contain duplicate content and for URLs without a trailing slash since we are using URLs WITH a trailing slash for all URLs across our site. We also recently added a no index, follow tag to all non-canonical URLs since we noticed a high number of duplicate content URLs in Google Webmaster Tools. The first part of my question is: How does a canonical work? Does the robot read the canonical and immediately go to the canonical URL or does it continue to read past the canonical tag and get to the no index, follow tag if there is one present? The second part of my question is: Is it necessary to have both a canonical tag and no index, follow tag in place? Or should the canonical tag be sufficient to avoid duplicate content? And lastly, if both a canonical tag and no index, follow tag are in place, should they be in a specific order? Canonical tag first then no index, follow tag second or no index, follow tag first then canonical tag second? I would appreciate any insight you can give. Thank you!

              Canonical Tag and Affiliate Links

              Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!

              Why should your title and H1 tag be different?

              Is it dangerous to have your H1 tag and your title the exact same thing?  My thought was that it's not be the best use of space, but that it couldn't cause harm. What do you think?
