Understanding What a Second-Level Domain Is and Tips for Choosing One for Your Website

A second-level domain is one component of the domain structure. A domain itself can be defined as a URL or website address, such as www.google.com, www.gmail.com, and many others.

A domain consists of three components: the subdomain, the Second-Level Domain (often abbreviated as SLD), and finally the Top-Level Domain (TLD). In this article, you’ll learn more about Second-Level Domains. Read the full discussion below.

What Is a Second-Level Domain?

To understand what a Second-Level Domain is, you first need to understand the overall structure of a domain. As you read at the beginning of this article, a domain consists of the following three components:

  • Subdomain: The very first part or the left side of the URL is called the subdomain; for example, “www.”
  • Second-Level Domain: The SLD is in the middle and is the most important part of a domain. Every website name in the middle—such as google, facebook, twitter, and others—is an example of an SLD.
  • Top-Level Domain: Finally, a domain ends with a TLD. Examples of TLDs include .com, .co.id, and .org.

From the discussion above, if applied to a URL example like www.google.com, you can immediately see that “www” is the subdomain, “google” is the SLD, and “.com” is the TLD. Do you now understand the overall structure of a domain?

The SLD plays a crucial role in a website. You need to find the right name to use as the SLD and later register it as a domain. Sometimes, the chosen domain name may not be available or is already in use by another website, so you’ll have to find a new SLD name.

In addition to choosing a name, you also need to register the SLD through a domain provider or hosting company like Cloudmatika. There are fees involved in registering an SLD, and you must renew it annually.

The SLD usage system is similar to a subscription model where you must renew it annually. Of course, you also need to pay an additional fee once a year to continue using the selected SLD.

What Are Some Tips for Choosing a Second-Level Domain Name?

Choosing a Second-Level Domain name cannot be done haphazardly. If you truly want to increase sales from your website, then consider a suitable and effective SLD name.

How do you choose an SLD name? Here are some tips you can follow.

1. Choose a Domain Name That’s Easy to Remember

The first and most important tip for choosing an SLD name is to select a domain name that’s easy to remember. You’ve probably come across various domain names that are too long and hard to remember, haven’t you? Especially if the domain name contains words with repeated letters, making it prone to typos.

To make it easier for internet users to find your website, you need to create a domain that’s easy to remember. Create a domain name consisting of no more than three words. You can use your company name as the domain name for branding purposes.

2. Check Domain Availability

Before finalizing your choice of a domain, you need to first ensure whether the selected name is available or not. It’s possible that the chosen domain name is already in use by another website. If so, then you’ll need to choose a new domain name, right?

So you don’t have to worry if one domain name isn’t available, create a variety of domain name options as backups. These can be used if the primary domain name you’ve chosen isn’t available.

3. Using a Relevant Domain Name

Sometimes there are many company names that are similar to or the same as other companies.

You certainly can’t avoid this. However, having the same company name will inevitably lead to the same domain name.

As an alternative, you can use a domain name that doesn’t directly include the company name but is still relevant to the business you’re running. For example, you have a company named PT. Anugerah Jaya Sentosa that operates in the animal feed industry. You can focus on “animal feed” as the domain name.

If used as an SLD, you could create www.pakanternakmurah.com or something similar. So, you still have various options for creating a domain name that is easy to remember and also aligns with the business you operate. Remember, the domain will affect your website’s search results on the SERP (Search Engine Results Page).

4. Include the Regional Name

In which region do you operate your business? If you run a business outside the capital city or in a specific region, you can include that regional name as part of your domain.

Using a regional name helps internet users identify your business’s location. This allows them to immediately consider shipping distances for purchased products or plan a visit to your location.

5. Avoid Unnecessary Symbols

Excessive use of symbols like (-) or (.) makes the domain difficult to type and may lead many internet users to make mistakes when entering it. Therefore, avoid using symbols for your SLD as much as possible.

6. Include Keywords

SEO plays a crucial role in boosting your brand or website’s ranking on Google’s first page. If possible, you can include relevant keywords to help improve your SEO score.

7. Choose the Right Top-Level Domain

In addition to the SLD, you also need to select the appropriate TLD that aligns with the purpose of your website. A TLD doesn’t always have to be .com. You can use .co.id for business activities conducted in Indonesia. Additionally, you can use .net if your website is technology-related.
