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. A subdomain name is a piece of information that is appended to the beginning of the domain name of a website. It enables websites to divide and arrange material for a specific purpose, such as a blog or an online store, from the rest of the site.
Let’s use shop.mywebsite.com as an example. In this case, the subdomain is ‘shop,’ the primary domain is ‘mywebsite,’ and the top level domain is ‘.com’. You can use any text as your subdomain, the simpler the name the better so it’s easier to remember.
A domain name usually consists of two parts: The top-level domain (TLD) is the extension of the domain name, such as.com or.org, while the second-level domain (SLD) is the distinctive portion of the domain name, usually a business or brand name. In the case of google.com, the TLD is com and the SLD is google.
The subdomain is the part of the URL that comes before the SLD. www, which stands for World Wide Web, is the most frequent subdomain. The homepage and the most significant pages of a website are located on this subdomain.
