Rather than registering a new domain name, you can always create a subdomain using a domain you already own.
A subdomain is a second website, with its own unique content, but there is no new domain name. Instead, you use an existing domain name and . The subdomain name looks like —— forums.domain.com
.com is top level domain or the domain extension
domain.com (wpcug.org) – is the 2nd level domain (SLD)
anything to the left of the SLD is the subdomain (even www)
a subdomain that points to a unique IP address
so you could have blog.wpcug.org if we had a blog page
subdomains vs subdirectories
Here’s the fact, if you set up your blog as a subdomain instead of a subdirectory, the ranking of your blog will suffer.
The Path: wpcug.org/folder/file.html
A path will usually refer to a file or folder (directory) on the
webserver (for example “/folder/file.html”)
If we talk about a URL, we usually mean the concrete path to a directory (http://www.domain.com/a-directory/) or a file (http://www.domain.com/documents/study.pdf) on a website.
It is, of course, not completely wrong to talk about a URL and simply mean the host- or domain name of a website, but we should try to use the correct terminology.
—- asubdomain is the subdomain of the site, asitename is the domain, and afolder is the subdirectory (also known as a folder).
A sub-domain is treated by the search engines as a truly unique website. So if you have one domain with 3 different subdomains established, each is treated differently by Google. Any “link juice” that has been established for the main site (or any of the sub-domains) isn’t necessarily passed onto the sub-domains. This is an important fact to remember, especially if you have a well-established site with a number of back-links. You’ll be starting over in terms of link building if you create a subdomain.
