What Is a Subdomain? – A Simple Guide
When activating a hosting plan or registering a domain name, most providers also offer a subdomain purchase. But what exactly is it, and above all when it is important to activate it?
What Is a Subdomain?
We start from the official definition provided by ICANN (Internet Corporation for Assigned Names and Numbers); a subdomain is a domain that resides within another domain.
To better understand the concept; you must think that each domain name is composed of a top-level domain; the extension (for example .co, .com, .org, and so on), a second-level domain, or the real name site and a third-level domain. The latter domain is considered a subdomain of the second-level domain, a subdomain of the top-level domain. In general, the term subdomain indicates a third-level domain.
Subdomain.dopinger.com can represent an example of a subdomain. The “subdomain” string represents a third-level domain of “dopinger.com”. It refers to a particular section of the site dedicated exclusively to the subdomain.
When to Activate a Subdomain?
In general, the usefulness of a subdomain is to refer to a specific section of the site. For example, in the case of a corporate website, it might be useful to have a subdomain dedicated to a particular top product, or assigned to the company blog or still dedicated to customer support and so on.
For large portals, the subdivision into subdomains is very useful. It allows you to manage the information better and facilitates the users’ orientation towards the contents of interest. Think of a multinational company operating in multiple sectors. It would be impossible to believe that we can manage all the information relating to the various sectors within a single site and, therefore, within a single domain. The most obvious thing is to activate as many subdomains as company sectors and manage the various sites separately even under the name of a single brand.
Advantages and Disadvantages of a Subdomain
The main advantage of one consists, based on what has been said so far, precisely in the better management of content. Thanks to the subdomains, it is possible to create different thematic categories, useful for users in the search for information. This possibility brings another intrinsic advantage; the division of content into categories with specific domains does nothing but improves the site’s indexing.
Unfortunately, most search engines consider subdomains as real domains separate from the main one. This means that it is as if you have multiple sites for each subdomain. From an SEO point of view, this division involves a double job. It’s necessary to proceed with the optimization operations not only on the main site but also on the various subdomains. You need to manage them just as if they were separate sites.
To understand if it is appropriate or not to activate one, you need to check if you have the time and resources to be able to cure a double site. If this is not possible, you can always move towards the use of subfolders of the type https://ift.tt/32yshWt. Which, however, offer the same results in terms of positioning.
Another small but somewhat negligible disadvantage is that you will need to treat the subdomains independently. In case you use paid themes or plugins, you will have to buy the tools you are using on the main domain and the subdomain.
This disadvantage is totally up to you, in that you decide whether or not to buy them is not something “mandatory.”
FAQs of Subdomains
It’s a traditional subdomain that states that the website is part of the web, and not other parts of the internet like Gopher or FTP.
Concisely, using www nowadays is time consuming. However, it’s easier to remember and write “www.dopinger.com”, rather than “https://ift.tt/32FaY5Y;
Up to 100 subdomains are allowed per domain.
Conclusion on Subdomains
To summarize, a subdomain is the part of a URL that comes before the “main” domain name and the domain extension.
Subdomains can help you divide your website into logical parts or create separate sites. Such as a separate blog for each sport.
