      Hello,

      We have a parallel mobile website and recently we implemented a link pointing to the desktop website. This redirect is happening via a javascript code and results in a url followed by this paramenter: ?m=off

      Example:
      http://www.m.website.com                                 redirects to:
      http://www.website.com/?m=off

      Questions:

      • Will the "http://www.website.com/?m=off" be considered duplicate content with "http://www.website.com" since they both return the same content?
      • Is there any possibility that Google will take into consideration the url ending in "/?m=off"? How should we treat this new url?
      • The webmaster tools URL parameter configuration at the moment isn't experiencing problems but should we submit the parameter anyway in order not to be indexed or should we wait first and see the error response?
      • In case we should submit this for removal... what's the best way to do it? Like this?
        • Parameter: ?m=off
      • Does this parameter change page content seen by the user? - doesn't affect page content

      Any help is much appreciated.
      Thank you!

        Hi again!

        It's normal that you feature very similar or even, duplicate content through both your mobile and desktop Website versions, what it is fundamental though is that you use the rel alternate and canonical tags that I shared with you in my previous answer. I've just checked your site and you're not using them.

        If you correctly add these tags in your mobile and desktop URLs as I described in my previous answer you shouldn't have any content duplication or cannibalization issues in Google's search results.

        Thanks!

        Aleyda

          Thanks Aleyda, mobile website development is something new for and since we developed this in house, we are not sure if we have done the right thing, if we have duplicate content. Is there any way we can check for duplicate content? Could you take a look at our website and its mobile version and let us know what you think?

          Thank you!

            Hi there!

            It's ok (and needed) in these circumstances to use a parameter in the URL since you cannot simply add a direct link otherwise your mobile users who select to switch to the desktop version will end-up in a redirection loop. What you can do to avoid any type of content duplication issues in this type of settings is:

            • Add a link rel="alternate" tag in each of the desktop URLs referring to their specific mobile URL versions and a link rel="canonical" tag in all of the mobile URLs referring to their specific desktop URLS versions, as specified here by Google. Take a look at an example here
            • Configure the appropriate canonical tags in your Desktop URLs as specified here by Google, so they always refer to their original URL versions (without parameters). This means that in http://www.website.com/?m=off you should add this canonical tag:```
              pointing to its original URL version... and do this with every URL (referring to its own original URL version).
              
              

            By doing this you won't have any content duplication issues. If you want to learn more about Mobile SEO take a look at the Webinar I did sometime ago in SEOmoz here and this post where I answer the most common Mobile SEO questions.

            Thanks,

            Aleyda

              The page ending in ?m=off is non existent. We are using Joomla and such page does not exist and cannot be configured via canonical tags. Any other suggestion?

              Thank you!

                Query parameters can become indexed by Google and can lead to duplicate content. Just make sure that you are using the canonical tag in your header pointing to the non-query parameter page, that way Google will know to index the proper URL.

                  Redirection chain and Javascript Redirect

                  Hi, A redirection chain is usually defined as a page redirecting to another page which itself is another redirection. URL1 ---(301/302)---> URL2 ---(301/302)---> URL3 But what about Javascript redirect? They seem to be a different beast: URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3 From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain. Most of the tools (such as moz) only see the first redirection. So is that scenario a redirection chain or no?

                  301 redirect adding trailing slash to url

                  I am looking into a .htacess file for a site I look after and have noticed that the urls are all 301 redirecting from a none slash directory to a trailing slashed directory/folders. e.g. www.domain.com/folder gets 301 redirected to www.domain.com/folder/ Will this do much harm and reduce the effect on the page and any links pointing to the site be lessened? Secondly I am not sure what part of my htaccess is causing the redirect. RewriteCond %{HTTP_HOST} !^www.domain.co.uk [NC] RewriteCond %{HTTP_HOST} !^$
                  RewriteRule ^(.*) http://www.domain.co.uk/$1 [L,R,NE] RewriteCond %{THE_REQUEST} ^./index.php
                  RewriteRule ^(.)index.php$ /$1 [R=301,L] or could a wordpress ifmodule be causing the problem? Any info would be apreciated.

                  Numbers in URL

                  Hey guys! Need your many awesome brains. 🙂 This may be a very basic question but am hoping you can help me out with some insights beyond "because Google says it's better". 🙂 I only recently started working with SEO, and I work for a SaaS website builder company that has millions of open/active user sites, and all our user sites URLs, instead of www.mydomainname.com/gallery or myusername.simplesite.com/about, we use numbers, so www.mysite.com/453112 or myusername.simplesite.com/426521 The Sales manager has asked me to figure out if it will pay off for us in terms of traffic (other benefits?) to change it from the number system to the "proper" and right way of setting up these URLs. He's looking for rather concrete answers, as he usually sits with paid search and is therefore used to the mindset of "if we do x it will yield us y in z months". I'm finding it quite difficult to find case studies/other concrete examples beyond the generic, vague implication that it will simply be "better" (when for example looking at SEO checklists and search engine guidelines). Will it make a difference? How so? I have to convince our developers of the importance and priority of this adjustment, or it will just drown in the many projects they already have. So truly, any insights would be so very welcome. Thank you!

                  Does it really matter to maintain 301 redirect after de-indexing of old URLs?

                  Today, I was reading latest blog post on SEOmoz blog about. Uncrawled 301s - A Quick Fix for When Relaunches Go Too Well This is very interesting study about 301 & How it useful to maintain traffic. I'm working on eCommerce website and I have done similar stuff on my website. I have big confusion to manage 301 redirect. My website generates new URLs due to following actions. Re-write dynamic URLs. Re-launch entire website on different eCommerce platform. [osCommerce to Magento Commerce] Re-name category. Trasfer one product from one category to another category. I'm managing my 301 redirect with old practice. Excel sheet data from Google webmaster tools and set specific new URLs for redirect. Hoooo... Now, I have 8.5K redirect in htaccess... And, I'm thinking it's too much. Can we remove old 301 redirect from htaccess or not? This is big question for me. Because, all pages are not hyperlink on external website. Google have just de-indexed old URLs and indexed new URLs. So, Is it require to maintain 301 redirect after Google process?

                  Redirect non-www if using canonical url?

                  I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks

                  Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?

                  Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian

                  Trailing Slashes In Url use Canonical Url or 301 Redirect?

                  I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?
