"Subdomain vs. Subfolder" Yes, this question has been asked many, many times, but I will try to ask it in a way that is not considered a duplicate, as my question is more about some of the features than the more modern billing and systems automated hosting. provide.
Correct me if I'm wrong, but I've read that when it comes to search robots, specifically google, subdomains and subdirectories are the same. But reading some Moz articles shows that there have been cases in conflict with what Google claims; specifically that subdomains can act as their own autonomous website.
Reading a post on Cloudflare puts it this way:
A subdomain is the same and different from a root domain. This means that the keywords for a subdomain are treated separately from the root domain.
Current configuration / Question
Now my question comes from some features that the billing software offers that I would rather not separate from the main domain. Specifically, the Knowledge Base, but also a download and server status section, albeit to a lesser extent.
I currently have a frequently asked questions page setup in my main subdomain which is www.domain.com (redirects other than www to www). Most of my website is on this main site (www.domain.com). I have set up a billing system hosted on a different server under one subdomain, let's call it my.domain.com.
I'd really like to start using the knowledge base that is built into the billing software CMS on the current / FAQ page that doesn't run on any type of CMS. This would make it much easier to manage, add and edit any information in these sections of the site.
But do I risk losing these keywords that would normally be associated with my main website (www.) Because now they would be hosted in my billing CMS subdomain?
One solution I thought of was having my billing software located on the main www. but in a subdirectory instead of a subdomain. For security reasons, the billing CMS would still be hosted on a different server, but you would simply configure a reverse proxy for www.domain.com/billing/etc … to load the billing CMS.
Am I stop thinking this?
Hosting a billing CMS in a subdomain is not a problem, but would the billing CMS knowledge base pages be associated with my primary domain or only the subdomain from which the billing CMS is accessed?
Is it a good idea to use a reverse proxy to allow access to the billing CMS in a subfolder instead of from a subdomain?
Are there issues or problems that I just don't see when it comes to where my FAQ / Knowledge Base, Downloads, Status pages are accessed?
