Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
-
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
- Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/
- 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.
- Change all absolute URLs to relative URLs on blog
- 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
- 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?
- 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?
- Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property?
- Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO?
- 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%

rewrite the URLs do not redirect

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

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
- 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
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>

301 Redirect in breadcrumb. How bad is it?
Hi all, How bad is it to have a link in the breadcrumb that 301 redirects? We had to create some hidden category pages in our ecommerce platform bigcommerce to create a display on our category pages in a certain format. Though whilst the category page was set to not visable in bigcommerce admin the URL still showed in the live site bread crumb. SO, we set a 301 redirect on it so it didnt produce a 404. However we have lost a lot of SEO ground the past few months. could this be why? is it bad to have a 301 redirect in the breadrcrumb.

301 Redirect of subdomain?
Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community. I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them? I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself. If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense. Any thoughts are appreciated. Thanks for your time.

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!

New Site: Use Aged Domain Name or Buy New Domain Name?
Hi,
Intermediate & Advanced SEO | | peterwhitewebdesign
I have the opportunity to build a new website and use a domain name that is older than 5 years or buy a new domain name. The aged domain name is a .net and includes a keyword.
The new domain would include the same keyword as well as the U.S. state abbreviation. Which one would you use and why? Thanks for your help!0 -
Any way to find which domains are 301 redirected to competitors' websites?
By looking at the work from an SEO collegue it became clear that his weak linkbuilding graph probably is not the cause for his good rankings for a pretty competitive keyword. (also no social mentions where found) I was wondering what it could be, site structure and other on page optimization factors seems to be ok and I don't think there will be exceptionally good or bad user behavior... Finally I looked at the competitors and found that they have more links, better content en better design, so I got a little stuck. The only reason I can think of is that he is doing 301 redirects (or is rel=canonical tags). Is there a way to trace these redirects back to the source in order to include this important variable in your competitor research? thnx

How To 301 Redirect .html pages
I need to redirect a page/URL that is purely .html to a new location. I don't know how to do this. All the redirects I can find are for server side code pages .php/.aspx etc. From my understanding I can't put a server side redirect in a .html file. I am hosting on a microsoft server, however the new page I am redirecting to is .php. I am running some WordPress (.php) files on the server. I need to make it redirect before the old page loads so visitors don't start reading something that is about to get redirected Can someone please help me?

How do you implement dynamic SEO-friendly URLs using Ajax without using hashbangs?
We're building a new website platform and are using Ajax as the method for allowing users to select from filters. We want to dynamically insert elements into the URL as the filters are selected so that search engines will index multiple combinations of filters. We're struggling to see how this is possible using symfony framework. We've used www.gizmodo.com as an example of how to achieve SEO and user-friendly URLs but this is only an example of achieving this for static content. We would prefer to go down a route that didn't involve hashbangs if possible. Does anyone have any experience using hashbangs and how it affected their site? Any advice on the above would be gratefully received.
