      Hi all, I'm assigned a site in Magento. After the first craw, we found almost 15k 302 redirects.

      A sample URL ends with this /stores/store/switch/?SID=qdq9mf1u6afgodo1vtvk0ucdpb&___from_store=default&___store=german&uenc=aHR0cHM6Ly9qdWljeWZsdXRlcy5jb20vP19fX3N0b3JlPWdlcm1hbg%2C%2C

      And they are currently 302 redirecting to the homepage as well as other main pages and also product pages it seems.

      Some of these point to account pages where customers log in. Probably best for me to de-index those so no issues there.

      But I'm worried about the 302 redirects to public pages.

      The extension we have installed is SEO Suite Ultimate by MageWorx.

      Does anyone here have experience here specifically and how did you fix it?

      Thanks,

      JC

        It turned out to be a language extension. We took it out and fixed everything except for a couple of links. I'm opening a new question for those. Thanks for all your help!

          Look at the template, as this is the likely culprit making links to these 302 redirects. If they are not required, simply remove any references to the link on your template?

          If they are necessary links as you say, customer login etc - add a nofollow tag and de-index the page.

          Ensure you have self-referencing canonical tags on the pages with lots of parameters.

          You could also remove the a tag to something less SEO friendly to reduce your potential crawl budget ensuring that your non-vital (product/category) pages exhume more importance.

          If you have so many links/pages, they will get lost within all the nonsense.

            @lasclients Hello, you should debug the redirections in this case. Here's what you can do in Magento 2:

            If you face an unexpected 301 or 302 redirect in Magento 2 and you don't know why it happens or what code causes it, you can easily find this out by temporarily editing the following files:

            /vendor/magento/framework/HTTP/PhpEnvironment/Response.php
            /var/www/html/m2_35ee/vendor/magento/framework/Controller/Result/Redirect.php
            

            Open Response.php and add the following line to the beginning of the setRedirect function:

            var_dump($url); \Magento\Framework\Debug::backtrace(false, true, false); exit();
            

            Example:

            public function setRedirect($url, $code = 302)
            {
                var_dump($url); \Magento\Framework\Debug::backtrace(false, true, false); exit();
                $this->setHeader('Location', $url, true)
                    ->setHttpResponseCode($code);
            
                return $this;
            }
            

            Now you open the second Redirect.php file and add this:

            var_dump($this->url); \Magento\Framework\Debug::backtrace(false, true, false); exit();
            

            After each line containing:

            $this->url =
            

            Example:

            public function setRefererUrl()
            {
                 $this->url = $this->redirect->getRefererUrl();
                 var_dump($this->url); \Magento\Framework\Debug::backtrace(false, true, false); exit(); 
                 return $this;
            }
            
            public function setRefererOrBaseUrl()
            {
                 $this->url = $this->redirect->getRedirectUrl();
                 var_dump($this->url); \Magento\Framework\Debug::backtrace(false, true, false); exit(); 
                 return $this;
            }
            
            public function setUrl($url)
            {
                 $this->url = $url;
                 var_dump($this->url); \Magento\Framework\Debug::backtrace(false, true, false); exit(); 
                 return $this;
            }
            
            public function setPath($path, array $params = [])
            {
                 $this->url = $this->urlBuilder->getUrl($path, $this->redirect->updatePathParams($params));
                 var_dump($this->url); \Magento\Framework\Debug::backtrace(false, true, false); exit(); 
                 return $this;
            }
            

            Save the corresponding changes and open a page that causes an unexpected redirect. You should see a debug backtrace with the information about the code line causing the redirect.

            If you don't see it, it means that the redirect is not caused by Magento code, but the webserver settings, or the third-party module code that uses not-recommended Magento programming practices.

            Hope this helps!

              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?

              Backlinks that go to a redirected URL

              Hey guys, just wondering, my client has 3 websites, 2 of 3 will be closed down and the domains will be permanently redirected to the 1 primary domain - however they have some high quality backlinks pointing the domains that will be redirected. How does this effective SEO? Domain One (primary - getting redesign and rebuilt) - not many backlinks
              Domain Two (will redirect to Domain One) - has quality backlinks
              Domain Three (will redirect to Domain One) - has quality backlinks When the new website is launched on Domain One I will contact the backlink providers and request they update their URL - i assume that would be the best.

              301 Redirects Relating to Your XML Sitemap

              Lets say you've got a website and it had quite a few pages that for lack of a better term were like an infomercial, 6-8 pages of slightly different topics all essentially saying the same thing.  You could all but call it spam. www.site.com/page-1 www.site.com/page-2 www.site.com/page-3 www.site.com/page-4 www.site.com/page-5 www.site.com/page-6 Now you decided to consolidate all of that information into one well written page, and while the previous pages may have been a bit spammy they did indeed have SOME juice to pass through. Your new page is: www.site.com/not-spammy-page You then 301 redirect the previous 'spammy' pages to the new page.  Now the question, do I immediately re-submit an updated xml sitemap to Google, which would NOT contain all of the old URL's, thus making me assume Google would miss the 301 redirect/seo juice.  Or do I wait a week or two, allow Google to re-crawl the site and see the existing 301's and once they've taken notice of the changes submit an updated sitemap? Probably a stupid question I understand, but I want to ensure I'm following the best practices given the situation, thanks guys and girls!

              How to fix Google index after fixing site infected with malware.

              Hi All Upgraded a Joomla site for a customer a couple of months ago that was infected with malware (it wasn't flagged as infected by google).  Site is fine now but still noticing search queries for "cheap adobe" etc with links to http://domain.com/index.php?vc=201&Cheap_Adobe_Acrobat_xi in web master tools (about 50 in total).  These url's redirect back to home page and seem to be remaining in the index (I think Joomla is doing this automatically) Firstly, what sort of effect would these be having on on their rankings?  Would they be seen by google as duplicate content for the homepage (moz doesn't report them as such as there are no internal links). Secondly what's my best plan of attack to fix them.  Should I setup 404's for them and then submit them to google?  Will resubmitting the site to the index fix things? Would appreciate any advice or suggestions on the ramifications of this and how I should fix it. Regards, Ian

              CNAME vs 301 redirect

              Hi all, Recently I created a website for a new client and my next job is trying to get them higher in Google. I added them in OSE and noticed some strange backlinks. To my surprise the client has about 20 domain names. All automatically poiting to (showing) the same new mainsite now. www.maindomain.nl www.maindomain.be
              www.maindomain.eu
              www.maindomain.com
              www.otherdomain.nl
              www.otherdomain.com
              ... Some of these domains have backlinks too (but not so much). I suggested to 301 redirect them all to the main site. Just to avoid duplicate content. But now the webhoster comes into play: "It's a problem, client has only 1 hosting account, blablabla...". They told me they could CNAME the 20 domains to the main domain. Or A-record them to an IP address. This is too technical stuff for me. So my concrete questions are: Is it smart to do anything at all or am I just harming my client? The main site is ranking pretty well now. And some backlinks are from their copy sites (probably because everywhere the logo links to the full mainsite url). Does the CNAME or A-record solution has the same effect as a 301 redirect, from SEO perspective? Many thanks,
              Hans

              What to do with 302 redirects being indexed

              Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/  (there is no content here, and never has been).  This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting.  Alternatively, I'd say a 301 redirect would be preferable.  But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way?  I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!
