      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://cloudz.click/learn/seo/redirection

              Best way to link to multiple location pages

              I am a Magician and have multiple location pages for each county I cover. I currently have them linked off the menu under locations/ <county>and also in the footer</county> However I have heard that a link from the page is much stronger, so I am experimenting with removing the Menu & Footer link and just linking to these pages from within the content. It's not really a navigation item and most people come in through search to the right page. Am I diluting the link by having it in the Menu/Page and Footer? I read a long time ago that Google only considers the first link to a page and ignores the rest - is that the case? Thanks Roger https://www.rogerlapin.co.uk/

              Adding https version of website: how best to redirect

              If I have 4 versions of my site http://www
              http://
              https://www
              https:// What is the best way to redirect without losing seo positions? i have been mainly using http://www but have recently added my ssl so https works also. I heard at Moz Con that I should get the https working. All of my marketing and ads are going to http://www 301 redirect 3 of them? Which 3? If https is becoming important, should that be my main url? will it hurt my seo to switch? Thank you so much in advance!

              Best practices for types of pages not to index

              Trying to better understand best practices for when and when not use a content="noindex".  Are there certain types of pages that we shouldn't want Google to index?  Contact form pages, privacy policy pages, internal search pages, archive pages (using wordpress).  Any thoughts would be appreciated.

              Best practice for URL - Language/country

              Hi, We are planning on having our website localized into more languages. We already have an English and German version. The German version is currently a sub-domain: www.example.com --> English version de.example.com --> German version Is this recommended? Or is it always better to have URLs with language prefixes such a: www.example.com/de www.example.com/es Which is a better practice in terms of SEO?

              What is the best way to deal with an event calendar

              I have an event calendar that has multiple repeating items into the future. They are classes that typically all have the same titles but will occasionally have different information. I don't know what is the best way to deal with them and am open to suggestions. Currently Moz anayltics is showing multiple errors (duplicate page titles, descriptions and overly dynamic urls). I'm assuming that it's showing duplicate elements way into the future. I thought of having the calendar no followed at all but the content for the classes seems valuable. Thanks,

              Image Height/Width attributes, how important are they and should a best practice site include this as std

              Hi How important are the image height/width attributes and would you expect a best practice site to have them included ? I hear not having them can slow down a page load time is that correct ? Any other issues from not having them ? I know some re social sharing (i know bufferapp prefers images with h/w attributes to draw into their selection of image options when you post) Most importantly though would you expect them to be intrinsic to sites that have been designed according to best practice guidelines ? 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?
