      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.

                  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?

                  Is 301 redirect the only way when using Vanity URLs?

                  We have been using vanity urls for some of our pages. Mostly the pages that have a vanity URL have a long URL length. But now the problem is, the vanity URL is getting displayed on the search engine when the particular keyword related to the page is entered. I checked the google search console, the vanity URL is indexed and the original URL remains unindexed. What should I do? Is adding 301 redirect to the vanity URLs are solution? Since some of vanity URLs are not redirecting to the original. Some of the original pages are not getting traffic. Also, can using canonical tag help?

                  My homepage redirects to itself?

                  Hi there - I'm not a SEO so help would be appreciated! Moz is telling me we have a redirect loop but the URLs are the same. https://www.example.com/ to https://www.example.com/ Why is my homepage creating a redirect loop to itself? We use Wordpress and I do not have any redirects listed for our homepage. Could this have something to do with switching to https in April? Thanks, Katherine

                  Redirect URLS with 301 twice

                  Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND.  However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS  have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the  "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

                  Removing Redirected URLs from XML Sitemap

                  If I'm updating a URL and 301 redirecting the old URL to the new URL, Google recommends I remove the old URL from our XML sitemap and add the new URL. That makes sense. However, can anyone speak to how Google transfers the ranking value (link value) from the old URL to the new URL? My suspicion is this happens outside the sitemap. If Google already has the old URL indexed, the next time it crawls that URL, Googlebot discovers the 301 redirect and that starts the process of URL value transfer. I guess my question revolves around whether removing the old URL (or the timing of the removal) from the sitemap can impact Googlebot's transfer of the old URL value to the new URL.

                  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

                  Someone is redirecting their url to mine

                  Hello, I have just discovered that a company in Poland www.realpilot.pl is directing their domain to ours www.transair.co.uk. We have not authorised this, neither do we want this. I have contacted the company and the webmaster to get it removed. If you search for the domain name www.realpilot.pl we (www.transair.co.uk) come up top. My biggest worry is that we will get penalised by Google for this re-direct as it appears to be done using some kind of frame. Does anyone know anything about this kind of thing? Many Thanks Rob Martin

                  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.
