          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://a-moz.groupbuyseo.org/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?

                  Duplicate Content Issue WWW and Non WWW

                  One of my sites got hit with duplicate content a while ago because Google seemed to be considering hhtp, https, www, and non ww versions of the site all different sites. We thought we fixed it, but for some reason https://www and just https:// are giving us duplicate content again. I can't seem to figure out why it keeps doing this. The url is https://bandsonabudget.com if any of you want to see if you can figure out why I am still having this issue.

                  Best & easiest way to 301 redirect on IIS

                  Hi all, What is the best and easiest way to 301 redirect URLs on IIS server? I got access to the FTP and WordPress back office, but no access to the server admin. Is there an easy way to create 301 redirect without having to always annoy the tech in charge of the server? Thanks!

                  Best Practices for adding Dynamic URL's to XML Sitemap

                  Hi Guys, I'm working on an ecommerce website with all the product pages using dynamic URL's (we also have a few static pages but there is no issue with them). The products are updated on the site every couple of hours (because we sell out or the special offer expires) and as a result I keep seeing heaps of 404 errors in Google Webmaster tools and am trying to avoid this (if possible). I have already created an XML sitemap for the static pages and am now looking at incorporating the dynamic product pages but am not sure what is the best approach. The URL structure for the products are as follows: http://www.xyz.com/products/product1-is-really-cool
                  http://www.xyz.com/products/product2-is-even-cooler
                  http://www.xyz.com/products/product3-is-the-coolest Here are 2 approaches I was considering: 1. To just include the dynamic product URLS within the same sitemap as the static URLs using just the following http://www.xyz.com/products/ - This is so spiders have access to the folder the products are in and I don't have to create an automated sitemap for all product OR 2. Create a separate automated sitemap that updates when ever a product is updated and include the change frequency to be hourly - This is so spiders always have as close to be up to date sitemap when they crawl the sitemap I look forward to hearing your thoughts, opinions, suggestions and/or previous experiences with this. Thanks heaps, LW

                  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?

                  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!

                  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.
