      We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this.

      • Blog subdomain URL is https://blog.example.com/ and
      • destination sub-directory URL is https://www.example.com/blog/

      Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website.

      Following is our Technical Setup

      1. Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/
      2. Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop.
      3. Change all absolute URLs to relative URLs on blog
      4. Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap.

      SEO Risk Evaluation

      We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are.

      Keeping this in mind, I am evaluating SEO Risks factors

      1. Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain?
      2. Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap?
      3. Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property?
      4. Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO?
      5. Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92%

          PS

          tools like CloudFlare & Fastly don’t care what you’re server is .

          https://blog.cloudflare.com/subdomains-vs-subdirectories-improved-seo-part-2/

          https://moz.com/community/q/reverse-proxy-a-successful-blog-from-subdomain-to-subfolder

          frontend ssl_in
          bind :443 ssl crt /etc/haproxy/website.com.combined
          acl root path /
          acl blog path_beg /blog
          acl sitedomain path_beg /leasopedia
          acl glossary path_beg /glossary
          acl wpadmin path_beg /wp-
          acl blog_search query -m reg ^s=.
          $
          acl blog_preview query -m reg ^p=.*$

          use_backend wpengine if blog OR sitedomain OR glossary OR wpadmin OR root blog_search OR root blog_preview
          default_backend main-site

          backend wpengine
          server wpengine examplecompany.wpengine.com:443 ssl ca-file /etc/ssl/certs/ca-certificates.crt

          backend main-site
          server main-site example.examplecompany.com.:443 ssl ca-file /etc/ssl/certs/ca-certificates.crt

          https://blog.examplecompany.com or https://examplecompany.com/blog.

          It’s worth noting that WPEngine does not recommend this practice. 

          For those that want to host at https://site.com/blog and do it with a managed WordPress hosting provider like WPEngine, this article is for you.

          (Note, WPEngine will automatically block your reverse proxy, so you will need to contact customer support and ask them to whitelist its IP address in their firewall. I found this to be a painless process thanks to the friendly support staff at WPEngine.)

          How?

          The trick to getting the blog to look like it’s living on the main site (but actually living elsewhere) is to use a reverse proxy.

          HAProxy is a powerful reverse proxy, though its configuration has a bit of a learning curve compared to Nginx or Apache.

          We use HAProxy internally because it works well with AWS Elastic Load Balancers, which frequently change their IP address. Learn more

          HAProxy config

          | 1 | bind *:443ssl crt/etc/haproxy/website.com.combined |

          You’ll need to use SSL, as all WPEngine installs redirect to SSL.

          Of note is that HAProxy expects your certificate chain and your private key to be combined into one file

          | 1 | acl |

          These are the pattern matching lines that we’ll use to determine which traffic is forwarded to WPEngine

          | 1 |

          use_backend wpengine ifblog orsitename ORglossary ORwpadmin ORroot blog_search ORroot blog_preview

          |

          This directs /blog*, /sitename*, /glossary* and /wp-* to WPEngine.

          You can replace these with your own blog and page paths configured in wordpress.

          This line also directs /?s= and /?p= to wordpress using the combined root and blog_search and blog_preview lines.

          These are necessary to making searching and page previews work in WordPress.

          | 1 | default_backend main-site |

          Everything that doesn’t match one of the above patterns will go to the main site.

          | 1 | backend wpengine |

          Directives in the frontend that resolve to this backed will route to the blog.

          | 1 | backend main-site |

          Directives in the frontend that resolve to this backed will route to your main site.

          I would use Fastly

            Hi I have done this for 20+ websites.

            Following is our Technical Setup

            1. Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/

            please remember that the hosting or reverse proxy on the server is so important. Some managed WordPress hosts do this better then others.

            https://pressidium.com/ now offers reverse proxy's on all plans for free

            https://pressidium.com/blog/2019/wordpress-reverse-proxy-how-universities-corporations-are-benefitting-from-reverse-proxy-setups/

            if you want to do this with out having to worry about it any problem I cannot stress how easy it is done by hosting the blog on Pagely.com it’s now free!

            (don’t worry about the $200 they don’t change it)

            https://support.pagely.com/hc/en-us/articles/213148558-Reverse-Proxy-Setup

            or kinsta for $50 more a month

            https://kinsta.com/knowledgebase/reverse-proxy/

            Pantheo.io (my go to host) now offers the “Advanced Global CDN” it lets you run a reverse proxy & much more via Fastly (my favorite CDN) the cost is very reasonable.

            https://pantheon.io/product/advanced-global-cdn

            Servebolt.com offers reverse proxy & hosts all PHP sites Wordpress too. They use CloudFlare & they will setup everything for you for free. They are also a full enterprise partner

            https://servebolt.com/help/article/cloudflare-workers-reverse-proxy/

            You  can also use Fastly, CloudFlare business, Incapsula, Cloudfront

            2.    Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop.

            This is something that is very easy I would use Fastly

            • Change all absolute URLs to relative URLs on blog

            NO don’t do that it will hurt your site & will not help you change the URLs they need to be rewritten not made relative it’s a very bad way of trying to do this and will not help your site.

            • Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap

            Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website.

            If  you’re website site is YMYL I would use Pagely but Linode , AWS can do this to  with Fastly or  Nginx

            https://thoughtbot.com/blog/host-your-blog-under-blog-on-your-www-domain

            <code>location /blog/ {
                proxy_pass https://blog.example.com;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
            }</code> 
            

            <code>please let me know if you need help
            Tom</code>

              Redirection of 100 domain to Main domain affects SEO?

              domain seo redirecting domain

              Hi guys, An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

              301 Redirecting from domain to subdomain

              We're taking on a redesign of our corporate site on our main domain.  We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

              Multilingual Site and 301 redirection

              Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

              DNS or 301 Website Redirect

              We are running a marketplace site, so we have thousands of vendors selling their products on our site. Each vendor has a Profile page and we are soon to launch a premium store-front that is white label. Many of these vendors will want to point a custom url to their premium store-front (which is a sub domain of the marketplace) and we are trying to get an understanding of how we should instruct them to point their url in a way that will give the main marketplace site the seo juice. We also want to understand what will show up in the address bar.  Will it be their url or our sub domain? Will any of the marketplace seo juice boost their url local listing status?

              Changing a parent category and 301 redirecting

              I have a set of three pages that are subpages of a parent. The structure is as follows: mysite.com/directory/personal-widgets mysite.com/directory/commercial-widgets mysite.com/directory/widgets-services The partent page name "directory" really isn't working for where I want these pages to evolve. So I want to change it to "guides" In a world without worrying about google, I would simply change the parent page to guides, so they look like this, and be done with it: mysite.com/guides/personal-widgets But, the obvious problem is that I have external links to the page now. And the pages have a nice PR. And they also have Facebook page Likes and I don't know if I'll lose those. I know that if I should do this I should redirect the pages to the new pages of course. My question is: Will redirecting the old URL to the new URL with a 301 cause anything negative to happen that I might not be expecting?  Does Google dislike Redirects for any reason, or understand they are sometimes necessary?

              Is it ok to use both 301 redirect and rel="canonical' at the same time?

              Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!
