      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

              Our clients Magento 2 site has lots of obsolete categories. Advice on SEO best practice for setting server level redirects so I can delete them?

              magento nginx

              Our client's Magento website has been running for at least a decade, so has a lot of old legacy categories for Brands they no longer carry. We're looking to trim down the amount of unnecessary URL Redirects in Magento, so my question is: Is there a way that is SEO efficient to setup permanent redirects at a server level (nginx) that Google will crawl to allow us at some point to delete the categories and Magento URL Redirects? If this is a good practice can you at some point then delete the server redirects as google has marked them as permanent?

              Best strategy to handle over 100,000 404 errors.

              I recently been given a site that has over one-hundred thousand 404 error codes listed in Google Webmasters. It is really odd because according to Google Webmasters, the pages that are linking to these 404 pages are also pages that no longer exist (they are 404 pages themselves). These errors were a result of site migration that had occurred. Appreciate any input on how one might go about auditing and repairing large amounts of 404 errors. Thank you.

              What is the best way to refresh a webpage of a news site, SEO wise?

              Hello all, we have a client which is a sports website. In fact it is a veyr big website and has a huge number of news per day. This is mostly the reason why it refreshes some of its pages with news list every 420 seconds. We currently use meta refresh. I have read here and elsewhere that meta refreshes should be avoided. But we don't do it to send to another page and pass any kind of page authority / juice. Is in this case javascript refresh better? Is there any other better way. What do you think & suggest? Thank you!

              Best URL-structure for ecommerce store?

              What structure will recommend to the product pages? Lets make an example with the keyword "Luxim FZ200" With category in url:
              www.myelectronicshop.com/digital-cameras/luxim-FZ200.html With /product prefix:
              www.myelectronicshop.com/product/luxim-FZ200.html Without category in url:
              www.myelectronicshop.com/luxim-FZ200.html I have read in a blog post that Paddy Moogan recommend /lluxim-FZ200.html - i think i prefer this version too. But I can see that many of the bigger ecommerce stores are using a /product prefix before the product name. What is the reason for this? and what is best practice?

              What is the best URL designed for a product page?

              Should a product page URL include the category name and subcategory name in it? Most ecommerce platforms it seems are designed to do have the category and sub-category names included in the URL followed by the product name. If that is the case and the same product is listed in more then 1 category and sub-category then will that product have 2 unique urls and as a result be treated as 2 different product pages by google?   And then since it is the same product in two places on the site won't google treat those 2 pages as having duplicate content? SO is it best to not have the category and sub-category names in the URL of a product page? And lastly, is there a preferred character limit for a URL to be less than in size? 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?

              What is best practice for redirecting "secondary" domain names?

              For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.
