A subdomain is a component of your primary domain name that is separate from it. Subdomains are used to organize and browse your website's various sections. On your primary domain, you can create many subdomains or child domains.
Consider the following scenario:
In this case, the subdomain is 'blog,' the primary domain is 'yourwebsite,' and the top level domain is '.com' (TLD). You can use any text as your subdomain, as long as it's simple to type and remember.
Subdirectories vs. subdomains
Subdirectories are another type of subfolder that can be applied as an extension of your primary domain. A subdirectory, on the other hand, would come after the main domain in your URL, whereas a subdomain would come before it. If you were to add the store as a subdirectory instead of a subdomain to greenfarms.com, it would display as greenfarms.com/store.
When it comes to arranging your website and its many subfolders, there is a lot of dispute about whether subdomains or subdirectories are better, especially in terms of search engine optimization. Let's take a look at some of the advantages and disadvantages of each.
Subdomain Use Cases
A subdomain is most commonly used to create a testing or staging version of a website. Developers frequently test new plugins and updates on a subdomain staging site before making them public.
A subdomain is also commonly used to construct an online eCommerce store. Because eCommerce sites are often more hard to set up, corporations often desire a distinct subdomain to handle transactions.
Companies have also used subdomains to create mobile websites (m.yoursite.com), location-specific sites (uk.yoursite.com), and website sub-sections.
You can install WordPress on your subdomain and have it function independently of your main website.
Subdomains such as 'guest.yourwebsite.com,' 'user.yourwebsite.com,' and others can be used to serve a specific group of people on your site. Users can create custom websites using website builder platforms such as WordPress.com, Blogger.com, and others.
Subdomains might help you organize your information more effectively on your website. The SEO of your main website is unaffected by the proper use of a subdomain. When in doubt, though, we advise keeping everything on the same domain and avoiding utilizing a subdomain for public webpages.
