SEO Implications of Subdomain structures.

I have a in-house server in which I run a few websites from, now I've never really done any SEO on these websites as they were just there for demonstration purposes to show off some work that I've done in the past. The server is setup in a structure like so:

| Root
--- | Website1
--- --- ...
--- | Website2
--- --- ...
--- | Website3
--- --- ...
--- | Website4

All of which have subdomains so: website1.domain.com website2.domain.com etc.

I'm working on a Business Project that I've kept on my local system currently with port 8080 blocked (Because I was running my server on port 8080), a modified Robot.txt file and a "DO NOT INDEX" Wordpress setting just for sanity.

Lets say I set up a subfolder on my local server, such as: public/mybusiness

Then I link the domain I purchased to mybusiness.domain.com, so that "mybusinessdomain.com" is actually "mybusiness.domain.com" would that have any effect on SEO? Would the other websites in different folders on the website effect SEO?

TL;DR: WILL HAVING MULTIPLE WEBSITES ON THE SAME HOST ON SEPERATE SUBDIRECTORIES EFFECT SEO

You'll have to be a bit more clear cause that's totally unreadable.

Is that a folder structure? Domain structure?

Where is hosted domain.com ? is that the root folder you referred to? Does it have a static IP, is it using the static IP of your connection?

So only this website is in local? Why would you block the port 8080? is your local & server somehow connected ?

is your local server connected to the internet and resolved by a domain name?

That makes no sense at all, you're referring to domains you never mentionned.

This was explained fairly clearly from what I can read in the OP. It's the folder structure on the server. Doman.com is linked to the "Root" directory. Subdomains are pointing to the Subdirectories. The answer to your question is both.

We have a 1Gbit/s Business connection as a personal network. The server is connected to the same network as our home computers. "Domain.com" is the domain that points to a static address for the Server on the network.

Because my Personal Computer and Server are on the same network. I blocked port 8080 so it could not be accessed from the internet. My Apache configuration is set to listen to port 8080.

See above.

The question was, would a domain that is linked to a subdirectory (EG: Root/website1) suffer from the other websites on the server. (EG: Root/website2 and Root/website3)

For example, if I purchased a domain called: MyBusinessWebsite.com and My server currently uses MyLocalServer.com; Would setting up MyBusinessWebsite.com to link to a Subdirectory (EG: Root/Website1) have any effect on the SEO considering (Root/Website2, etc) exists. Since MyBusinessWebsite.com would be linked to a separate address on the same server(Our server has three static IP addresses) it would be accessible by Both: MyBusinessWebsite.com and website1.MyLocalServer.com as the Subdirectory for the business website would be a child of Root.

In your case, having subfolder of Root resolving to sudomain or mylocalserver.com is a bad idea, even if convenient when your create new project.

In this specific case, if MyBusinessWebsite.com & website1.MyLocalServer.com are both the same website and both indexable, you will have a duplicate content problem, and there is no real way to prevent that or to tell which one will take over. Your solution is to rething the automated structure you implemented so that it doesnt create a subdomain.
