      Hello,

      So I have searched the Q & A , Google, the zen cart forum and at this point I am looking for some one to give a concrete answer on what I should do.  There is a lot of different opinions on " rel=canonical" and how to apply it , since there are many other variable in place.

      I have a zen cart site.  I am using the latest 1.3.9 version.  The default setting ( seem to me) uses the  rel=canonical to point back to the specific link product or category respectively.

      Most of the time I have two scenarios.

      1. Main category --->  Sub category----> Product

      2. Main Category----> Product

      I'll give an example

      http://www.perfectindesign.com/awards ---main category

      http://www.perfectindesign.com/awards/acrylic-awards sub category

      http://www.perfectindesign.com/awards/acrylic-awards/slanted-award  product

      (this example has three sub categories with maybe 12 products in one 4 in the second and 5 in the third)

      From looking at the source code for each url it the rel=canonical just points back to its own url.

      I want to avoid competing against my self, for the example above keyword "acrylic awards" so should the use of the re=canonical be changes site wide to have products point back to sub categories when they exist and have products point back to main categories when no sub categories exist?

      I am very new to seo, specifically eCommerce seo.   If you have experience and have done this to a site you manage for a client or your own please advise how to proceed. Also if I'm missing some thing that will give me a better understanding of the bigger seo picture that would be great.

      Thanks,

      Yevgeny

        Did you end up removing the rel=canonical tag? I don't see it in your source.

        If you did, that is the right move. Canonical link tag should be used as a last resort. And should only really be used if you are currently having canonical issues or the CMS/cart you are using is known to have these problems.

        Ideally canonical problems should be fixed from a technical standpoint first.

          Rel=canonical on Godaddy Website builder

          Hey crew! First off this is a last resort asking this question here. Godaddy has not been able to help so I need my Moz Fam on this one. So common problem My crawl report is showing I have duplicate home pages www.answer2cancer.org and www.answer2cancer.org/home.html I understand this is a common issue with apache webservers which is why the wonderful rel=canonical tag was created! I don't want to go through the hassle of a 301 redirect of course for such a  simple issue. Now here's the issue. Godaddy website builder does not make any sense to me. In wordpress I could just go add the tag to the head in the back end. But no such thing exist in godaddy. You have to do this weird drag and drop html block and drag it somewhere on the site and plug in the code. I think putting before the code instead of just putting it in there. So I did that but when I publish and inspect in chrome I cannot see the tag in the head! This is confusing I know. the guy at godaddy didn't stand a chance lol. Anyway much love for any replies!

          301 redirect: canonical or non canonical?

          Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

          Rel canonical between mirrored domains

          Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...)  So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content.  I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
          -The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
          -The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!

          Adding Rel Canonical to multiple pages

          Hi, Our CMS generates a lot of duplicate content, (Different versions of every page for 3 different font sizes). There are many other reasons why we should drop this current CMS and go with something else, and we are in the process of doing that. But for now, does anyone know how would I do the following: I've created a spreadsheet that contains the following: Column 1: rel="canonical" tag for URL Column 2: Duplicate Content URL # 1 Column 3: Duplicate Content URL # 2 Column 4: Duplicate Content URL # 3 I want to add the tag from column 1 into the head of every page from column 2,3, and 4. What would be a fast way to do this considering that I have around 1800 rows. Check the screenshot of the builtwith.com result to see more information about the website if that helps. Farris bxySL

          Internal search : rel=canonical vs noindex vs robots.txt

          Hi everyone, I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I  know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem. The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!! I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too... The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this) Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless... Is there somebody who can tell me which option is the best to keep this traffic ? Thanks a million

          Delete old site but redirect domain to a new domain and site

          I just have a quick query and I have a feeling about what the answer is so just wanted to see what you guys thought... Basically I am working on a client site. This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?

          Google.ca is showing our US site instead of our Canada Site

          When our Canadian users who search on google.ca for our brand (e.g. Travelocity, Travelocity hotels, etc.), the first few results our from our US site (travelocity.com) rather than our Canadian site (travelocity.ca). In Google Webmaster Tools, we've adjusted the geotargeting settings to focus on the appropriate locale, but the wrong country TLD is still coming up at the top via google.ca. What's the best way to ensure our Canadian site comes up instead of the US site on google.ca? Thanks, Tory Smith
