Subdomain
A subdomain is a division or extension of the main domain. It is used to organize and divide the content of the website into distinct sections that can be navigated separately. Subdomains are preceded by the main domain and separated by a period.
Typically, a subdomain is used to create areas of the site dedicated to specific content or functionality, such as a blog, online store, or events section.
For example, if the domain is “www.example.com,” a subdomain might be “blog.example.com.”
Unlike subfolders, subdomains function almost like separate domains within a main domain and are used to organize content that has some autonomy or that targets different audiences. For example, a company might have a subdomain “store.example.com” for its online store and another “blog.example.com” for its corporate blog.
Search engines may treat subdomains as separate entities from the main domain, which means that traffic, authority, and links to subdomains may not directly benefit the main domain.
Therefore, the decision to use subdomains should be weighed against the SEO goals and overall site structure.
