      How is the best way to handle all the different variations of a website in terms of www | non www | http | https?

      In Google Search Console, I have all 4 versions and I have selected a preference.

      In Open Site Explorer I can see that the www and non www versions are treated differently with one group of links pointing to each version of the same page. This gives a different PA score.

      eg.

      1. http://mydomain.com DA 25 PA 35
      2. http://www.mydomain.com DA 19 PA 21

      Each version of the home page having it's only set of links and scores.

      Should I try and "consolidate" all the scores into one page?

      Should I set up redirects to my preferred version of the website?

      Thanks in advance

            Hi Samantha,

            What you have is what are called "canonical issues." By allowing multiple versions of your domain open and crawlable to search engines you "split" your ranking authority and result in the issues you are seeing right now.

            The best practice is to choose one version of your domain as the "true canonical" and then 301 redirect the others at the server level by means of mod_rewrite code. Doing so will consolidate your content, incoming links and PageRank and greatly increase the root domain authority of your site.

            To search engines, if your site hasn't instituted 301 redirect commands at the server level, all of these versions of your site home page would be treated as "separate pages" and each would accumulate authority individually:

            http://yoursite.com/
            http://www.yoursite.com/
            http://yoursite.com/index.php
            http://www.yoursite.com/index.php
            https://yoursite.com
            https://www.yoursite.com

            You get the idea.

            Most websites are run on one of three different types of servers...

            • Unix-based servers running Apache.
            • Unix-based servers running Nginx.
            • Microsoft Windows-based servers running IIS or similar.

            If you're unsure of what kind of server runs your site, ask your hosting company. Most sites are run on Unix-based servers with Apache. In that case, the server's behavior is configured using something called the .htaccess file.

            If your site's root domain already contains a .htaccess file, you can simply scroll to the end of whatever code is already there and append your 301 redirect code at the bottom of the file, starting on a new line. While this may sound complicated, it's actually very, very simple to do. If you can upload files to and from your Web server, then chances are you'll have no trouble managing (i.e. altering or creating and uploading) your .htaccess file(s).

            But yes, bottom line, you ALWAYS want to consolidate URLs and present one uniform "preferred" URL format to search engines and users. In your case, that would appear to the be the non-www domain which has the higher Domain Authority.

            You can learn all about redirection best practices at the Moz resource here: https://moz.com/learn/seo/redirection

              Best redirect destination for 18k highly-linked pages

              redirect redirect chain technical seo 301 redirects

              Technical SEO question regarding redirects; I appreciate any insights on best way to handle. Situation: We're decommissioning several major content sections on a website, comprising ~18k webpages. This is a well established site (10+ years) and many of the pages within these sections have high-quality inbound links from .orgs and .edus. Challenge: We're trying to determine the best place to redirect these 18k pages. For user experience, we believe best option is the homepage, which has a statement about the changes to the site and links to the most important remaining sections of the site. It's also the most important page on site, so the bolster of 301 redirected links doesn't seem bad. However, someone on our team is concerned that that many new redirected pages and links going to our homepage will trigger a negative SEO flag for the homepage, and recommends instead that they all go to our custom 404 page (which also includes links to important remaining sections). What's the right approach here to preserve remaining SEO value of these soon-to-be-redirected pages without triggering Google penalties?

              Google tries to index non existing language URLs. Why?

              Hi, I am working for a SAAS client. He uses two different language versions by using two different subdomains.
              de.domain.com/company for german and en.domain.com for english. Many thousands URLs has been indexed correctly. But Google Search Console tries to index URLs which were never existing before and are still not existing. de.domain.com**/en/company
              en.domain.com
              /de/**company ... and an thousand more using the /en/ or /de/ in between. We never use this variant and calling these URLs will throw up a 404 Page correctly (but with wrong respond code  -  we`re fixing that 😉 ). But Google tries to index these kind of URLs again and again. And, I couldnt find any source of these URLs. No Website is using this as an out going link, etc.
              We do see in our logfiles, that a Screaming Frog Installation and moz.com w opensiteexplorer were trying to access this earlier. My Question: How does Google comes up with that? From where did they get these URLs, that (to our knowledge) never existed? Any ideas? Thanks 🙂

              Disallow: /404/ - Best Practice?

              Hello Moz Community, My developer has added this to my robots.txt file: Disallow: /404/ Is this considered good practice in the world of SEO? Would you do it with your clients? I feel he has great development knowledge but isn't too well versed in SEO. Thank you in advanced, Nico.

              Having www. and non www. links indexed

              Hey guys, As the title states, the two versions of the website are indexed in Google. How should I proceed? Please also note that the links on the website are without the www. How should I proceed knowing that the client prefers to have the www. version indexed. Here are the steps that I have in mind right now: I set the preferred domain on GWMT as the one with www. I 301 redirect any non www. URL to the www. version. What are your thoughts? Should I 301 redirect the URL's? or is setting the preference on GWMT enough? Thanks.

              Rel=Canonical, WWW vs non WWW and SEO

              Okay so I'm a bit of a loss here.  For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar.  I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise?  Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same?  Or am I wrong and all that link juice and authority passes just the same?

              Found a Typo in URL, what's the best practice to fix it?

              Wordpress 3.4, Yoast, Multisite The URL is supposed to be "www.myexample.com/great-site" but I just found that it's "www.myexample.com/gre-atsite" It is a relatively new site but we already pointed several internal links to "www.myexample.com/gre-atsite" What's the best practice to correct this? Which option is more desirable? 1.Creating a new page I found that Yoast has "301 redirect" option in the Advanced tap Can I just create a new page(exact same page) and put noindex, nofollow and redirect it to http://www.myexample.com/great-site OR 2. htacess redirect rule simply change the URL to http://www.myexample.com/great-site and update it, and add Options +FollowSymLinks RewriteEngine On
              RewriteCond %{HTTP_HOST} ^http://www.myexample.com/gre-atsite$ [NC]
              RewriteRule ^(.*)$ http://www.myexample.com/great-site$1 [R=301,L]

              What is the best website structure for SEO?

              I've been on SEOmoz for about 1 month now and everyone says that depending on the type of business you should build up your website structure for SEO as 1st step. I have a new client click here   ( www version doesn't work)... some bugs we are fixing it now. We are almost finished with the design & layout. 2nd question have been running though my head. 1. What would the best url category for the shop be    /products/     - current url cat ex:   /products/door-handles.html 2. What would you use for the main menu as section for getting the most out of SEO. Personally i am thinking of making 2-3 main categories on the left a section where i can add content to it (3-4 paragraphs... images maybe a video).So the main page focuses on the domain name more and the rest of the sections would focus on specific keywords, this why I avoid cannibalization. Main keyword target is "door handles" Any suggestions would be appreciated.

              Double byte characters in the URL - best avoided?

              We are doing some optimisation on sites in the APAC region, namely China, Hong Kong, Taiwan and Japan. We have set the url generator to automatically use the heading of the page in the URL which works fine for countries using Latin characters, but is causing problems, particularly in IE, when it comes to the double byte countries. For some reason, IE struggles with double byte and displays URLs in their rather ugly, coded form. Anybody got any suggestions on whether we should persist with the keyword URLs or revert to the non-descriptive URLs for the double byte countries? The reason I ask is it's a balance of SEO benefit vs not scaring IE users off with ugly URLs that look dreadful and spammy.
