      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

              Non-Existent Parent Pages SEO Impact

              Hello, I'm working with a client that is creating a new site. They currently are using the following URL structure: http://clientname.com/products/furry-cat-muffins/ But the landing page for the directory /products/ does not actually have any content. They have a similar issue for the /about/ directory where the menu actually sends you to /about/our-story/ instead of /about/. Does it hurt SEO to have the URL structure set up in this way and also does it make sense to create 301 redirects from /about/ to /about/our-story/?

              Best practices for controlling link juice with site structure

              I'm trying to do my best to control the link juice from my home page to the most important category landing pages on my client's e-commerce site. I have a couple questions regarding how to NOT pass link juice to insignificant pages and how best to pass juice to my most important pages. INSIGNIFICANT PAGES: How do you tag links to not pass juice to unimportant pages. For example, my client has a "Contact" page off of there home page. Now we aren't trying to drive traffic to the contact page, so I'm worried about the link juice from the home page being passed to it. Would you tag the Contact link with a "no follow" tag, so it doesn't pass the juice, but then include it in a sitemap so it gets indexed? Are there best practices for this sort of stuff?

              ECommerce: Best Practice for expired product pages

              I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

              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?

              Blogs are best when hosted on domain, subdomain, or...?

              I’ve heard the it is a best practice to host your blog within your site. I’ve also heard it’s best to put it on a subdomain.  What do you believe is the best home for your blog and why?

              Hreflang on non-canonical pages

              Hi! I've been trying to figure out what is the best way to solve this dilemma with duplicate content and multiple languages across domains. 1 product info page 2 same product but GREEN
              3 same product but RED
              4 same product but YELLOW **Question: ** Since pages 2,3,4 just varies slightly I use the canonical tag to indicate they are duplicates of page 1. Now I also want to indicate there are other language versions with the_ rel="alternate" hreflang="x" _element. Should I place the _rel="alternate" hreflang="x" _on the canonical page only pointing to the canonical page with "x" language. Should I place the _rel="alternate" hreflang="x" _on all pages pointing to the canonical page with the "x" language? Should I place the _rel="alternate" hreflang="x"  _on all pages and then point it to the translated page (even if it is not a canonical page) ? /Lars
