What is a subdomain?

A subdomain is a domain that is part of the main domain.

For example asubdomain.example.com is a subdomain of example.com.

Is ‘www’ still a subdomain?

Technically speaking www.example.com is also a subdomain of example.com – there is nothing special about the characters www other than that they are frequently used by companies for their front facing website.

Subdomain or directory, which is best for SEO?

Whether to use a subdomain or directory is a question that gets debated a lot, many SEOs would say there is no right answer – and many have a preference for one or the other depending on the situation.

If you want to have a more separate website, isolated from your main domain, a subdomain could be a good choice. Whereas a directory will share authority with your main domain.
