      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!

          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.

                  Is there a limit to Internal Redirect?

                  I know Google says there is no limit to it but I have seen on many websites that too many 301 redirects can be a problem and might negatively affect your rankings in SERPs. I wanted to know especially from people who worked on large ecommerce site. How do they manage internal redirect from one URL to other and how many according to you are too many. I mean if you get a website that contain 300 plus 301 redirections within the website, how will you deal with that? Please let me know if the question is not clear.

                  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!

                  How do I deindex url parameters

                  Google indexed a bunch of our URL  parameters. I'm worried about duplicate content. I used the URL parameter tool in webmaster to set it so future parameters don't get indexed. What can I do to remove the ones that have already been indexed? For example, Site.com/products and site.com/products?campaign=email have both been indexed as separate pages even though they are the same page. If I use a no index I'm worried about de indexing the product page. What can I do to just deindexed the URL parameter version? Thank you!

                  XML Sitemap and unwanted URL parameters

                  We currently don't have an XML sitemap for our site. I generated one using Screaming Frog and it looks ok, but it also contains my tracking url parameters (ref=), which I don't want Google to use, as specified in GWT. Cleaning it will require time and effort which I currently don't have. I also think that having one could help us on Bing. So my question is: Is it better to submit a "so-so" sitemap than having none at all, or the risks are just too high? Could you explain what could go wrong? Thanks !

                  Old URL redirect to New URL

                  Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe

                  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?

                  How best to redirect URL from expired classified ads?

                  We have problem because our content are classifieds. Every ad expired after one or two mounts and then ad becomes inactive and we keep his page for one mount latter like a same page but we ad a notice that ad is inactive. After that we delete the ad and his page but need to redirect that URL to search results page which contains similar ads because we don't want to lose the traffic form that pages. How is the best way to redirect ad URL? Our thinking was to redirect internal without 301 redirection because the httacces file will be very big after a while  and we are thinking to try a canonicalization because we don't want engine to think that we have to much duplicate content.
