If you’re still trying to understand domains, you may have questions like, what is a top-level domain (TLD)?
In the Domain Name System (DNS) hierarchy, TLD refers to the highest level of a domain name. It’s what follows after the final dot in any given web/internet address. Examples of common TLDs are .com, .org, .gov, .edu, and .net. Read on to learn more about top-level domains, their types, and their importance.
Understanding top-level domains
Top-level domains are also known as URL extensions, domain suffixes, and domain extensions. TLDs are essential in the DNS hierarchy. Whenever a user types in a domain name in their web browser, DNS resolvers communicate with the TLD server. Then, the DNS server gives the resolver the IP address of the origin server where the domain that the user is asking for is hosted.
TLDs also help you easily determine and organize sites according to their purpose, location, or content. For example, .gov is meant for government agencies, and .com is designated for commercial businesses.
Types of top-level domains
The two common types of top-level domains are generic top-level domains and country code top-level domains:
Generic top-level domains (gTLDs)
Generic TLDs or gTLDs are the most common TLDs, which contain three or more characters. Examples include .net, .org, .com, and .edu. Before, the Internet Corporation for Assigned Names and Numbers (ICANN) put restrictions on the use of new gTLDs. However, they’ve been eased since 2010. Examples of less popular gTLDs are .loan, .top, .design, even .dog.
Country code top-level domains (ccTLDs)
Country code top-level domains or ccTLDs are meant for countries, territories, and sovereign states. Those types of TLDs were intended for websites from a specific country or territory or those with businesses in the region to use those given ccTLDs. Nowadays, however, the practical applications of these rules aren’t so strict, and most users can register most country code TLDs easily.
Generally, though, ccTLDs can help you guide customers on where you’re based and what countries you serve. Examples of ccTLDs are .ca for Canada, .de for Germany, .au for Australia, and .br for Brazil.
Beyond what is a top-level domain (TLD): importance of TLDs
Aside from understanding what is a top-level domain (TLD), you should also recognize its importance. For instance, TLDs help you communicate your brand message and market your brand. Using a common TLD like .com helps build trust and credibility as well. Users can be confident that the TLD is legitimate.
Moreover, TLDs are beneficial for search engine optimization (SEO). They may not have a direct impact on your Google ranking, but they influence people’s perceptions of your brand. Using simple and popular domain extensions can also help you drive traffic compared to complex and unfamiliar TLDs. ccTLDs usually rank well in local search results compared to gTLDs.
You can also get a trademark for your domain names, including TLDs, for better protection of intellectual property.
Top-level domains help with branding and marketing, SEO, protection of intellectual property, and building trust and credibility. To choose the right TLD for your website, consider your goals, like targeting a global audience or targeting an audience per country. More importantly, pick a TLD that captures what your website or brand is all about.
