      Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load:

      <script> //Inject canonical link into page head
          if (window.location.href.indexOf("/subdirname1") != -1) {
              canonicalLink = window.location.href.replace("/kapiolani", "");
          }
          if (window.location.href.indexOf("/subdirname2") != -1) {
              canonicalLink = window.location.href.replace("/straub", "");
          }
          if (window.location.href.indexOf("/subdirname3") != -1) {
              canonicalLink = window.location.href.replace("/pali-momi", "");
          }
          if (window.location.href.indexOf("/subdirname4") != -1) {
              canonicalLink = window.location.href.replace("/wilcox", "");
          }
          if (canonicalLink != window.location.href) {
              var link = document.createElement('link');
              link.rel = 'canonical';
              link.href = canonicalLink;
              document.head.appendChild(link);
          } script>

        I believe it's a limitation of our CMS. I'll see if we can try it in htaccess or PHP. Thanks for the insight.

          Thanks for the reply. Doesn't appear Google is recognizing the tag because duplicate pages with it are still showing up in SERPs.

            I Wouldn't bet on that working. Why not use the exact same code in .htaccess format, or even PHP? Javascript is a coding language that is parsed after the window starts loading, it's not like PHP where it gets parsed before the load.

            Thanks

              Hi SoulSurfer,

              Read This http://searchengineland.com/tested-googlebot-crawls-javascript-heres-learned-220157

              The google bot was able to read rel=nofollow and links were not followed. So I would think the same for rel=canonical as well.

              Thanks,

              Don

                Canonical or hreflang?

                I have four English sites for four different countries, UK, Ireland, Australia and New Zealand and I want to share some content between the sites. On the pages that share the content, which is essentially exactly the same on all 4 sites, do I use the hreflang tags like: or do I add a canonical tag to the other three pointing to the "origin", which would be the UK site? I believe it is best practice to use one or the other, but I'm not sure which make sense in this situation.

                Rel=canonical Weebly

                My problem is with my website as it says I have duplicate page titles and contents because of a /index.html. It says the duplicate content is due to the fact that my homepage on my website is www.seacandytackle.com but it is also www.seacandytackle.com/index.html because I use weebly. How can I use the tag to fix this? It won't let me do a 301 redirect because it is a home page. How can I fix this? What code would I have to use and which url? Also it says that I have duplicate page content between http://www.seacandytackle.com/index.html and http://www.seacandytackle.comhttp://www.seacandytackle.com but I don't recall having any page that looks like http://www.seacandytackle.com http://www.seacandytackle.com from weebly. How can I fix this issue as well? Thank you for any help. Step by step implementation would be particularly helpful in using the rel= tags to fix these duplicate issues.

                Canonical tag for Home page: with or without / at the end???

                Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL. We have incoming links to the homepage as http://www.mysite.com (without the backslash), and as http://www.mysite.com/ (with the backslash), and as http://www.mysite.com/index.html I know that there should be 301 redirects to just one version, but I need to know more about the canonical tags... Which should the canonical tag be??? (without the backslash) or (with the backslash) Thanks for your help! 🙂

                Google not pulling my favicon

                Several sites use Google favicon to load favicons instead of loading it from the Website itself. Our favicon is not being pulled from our site correctly, instead it shows the default "world" image. https://plus.google.com/_/favicon?domain=www.example.com Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site. Any idea why is this happening? Or how to "ping" Google to update that?

                Should I include tags in sitemap?

                Hello All, I was wondering if you should include tags and categories in your sitemap. In the past on previous blogs I have always left tags and categories out. The reason for this is a good friend of mine who has been doing SEO for a long time and inhouse always told me that this would result in duplicate content. I thought that it would be a great idea to get some input from the SEOmoz community as this obviously has a big affect on your blog and the number of pages indexed. Any help would be great. Thanks, Luke Hutchinson.

                Do I need to add canonical link tags to pages that I promote & track w/ UTM tags?

                New to SEOmoz, loving it so far. I promote content on my site a lot and am diligent about using UTM tags to track conversions & attribute data properly. I was reading earlier about the use of link rel=canonical in the case of duplicate page content and can't find a conclusive answer whether or not I need to add the canonical tag to these pages. Do I need the canonical tag in this case? If so, can the canonical tag live in the HEAD section of the original / base page itself as well as any other URLs that call that content (that have UTM tags, etc)? Thank you.

                Google Off/On Tags

                I came across this article about telling google not to crawl a portion of a webpage, but I never hear anyone in the SEO community talk about them. http://perishablepress.com/press/2009/08/23/tell-google-to-not-index-certain-parts-of-your-page/ Does anyone use these and find them to be effective? If not, how do you suggest noindexing/canonicalizing a portion of a page to avoid duplicate content that shows up on multiple pages?
