A top-level domain (TLD) is the last part of a web address, coming after the final dot. Common examples include “.com,” “.org,” and “.net.”
TLDs help organize the internet by categorizing websites based on their purpose or geographic location. They’re an essential component of a website’s domain name, which serves as a unique identifier for your site on the internet.
Top-Level Domain Examples
Top-level domains were created in the 1980s when the internet started to grow. They played a key role in the Domain Name System (DNS), which was designed to organize and manage the increasing number of websites.
The first TLDs were split into three groups: Categories, Multi-Organizations, and Countries. Each TLD had a special purpose, helping to classify websites based on their function or location.
Most Common Top-Level Domains
- .com - Commercial websites
- .org – Organizations
- .int – Intergovernmental organizations
- .edu - Educational institutions
- .gov – Government agencies
- .mil – U.S. military
These early TLDs made it easier for users and search engines to understand a website’s purpose. As the internet has grown, new TLDs have been introduced, giving website owners more choices and flexibility.
New Top-level Domains
Google Registry launched new top-level domains in May 2023:
- .Foo: A secure domain for developers, great for various programming projects
- .Zip: A secure domain symbolizing speed, ideal for fast content hosting
- .Mov: A secure domain for moving pictures or anything dynamic
- .Nexus: A secure domain to serve as a hub for various online activities
- .Dad: A secure domain for dads or fatherhood-related content
- .Phd: A domain for those with a doctorate to showcase their skills
- .Prof: A domain for professors to display their credentials, research, and publications
- .Esq: A secure domain for lawyers or distinguished individuals to highlight their achievements
Types of Top-Level Domains
The Internet Corporation for Assigned Names and Numbers (ICANN) manages the Internet Assigned Numbers Authority (IANA), which regulates and assigns domain names on the internet.
Here’s a breakdown of the main types of TLDs and what they’re used for:
Generic Top-Level Domains (gTLDs)
These are the most common TLDs and include .com, .org, and .net. They’re open for use by anyone in the world and can be used for a wide range of purposes. As of April 2023, there are 1,249 generic top-level domains, providing you with many options for selecting a TLD that suits your needs.
Generic-Restricted Top-Level Domains (grTLD)
TLDs like .biz, .edu, and .gov are reserved for specific purposes. For instance, .biz is intended for businesses, .edu is for educational institutions, and .gov is for government entities. Other TLDs also have dedicated purposes, so it’s crucial to choose a TLD that aligns with your website’s goals and audience.
Sponsored Top-Level Domains (sTLDs)
These TLDs are sponsored by specific organizations or communities and are often restricted to members of that group. Examples include .aero for the aviation industry and .museum for museums.
Country Code Top-Level Domains (ccTLDs)
ccTLDs are country-specific TLDs, like .us for the United States, .uk for the United Kingdom, and .ca for Canada. They’re useful for targeting a specific country but may limit your website’s visibility in other places. For a global brand, it’s better to use a gTLD like .com, .org, or .net that aren’t restricted by geography.
Test Top-Level Domains (tTLD)
tTLDs are for testing and experimental purposes only, like .test, .invalid, and .localhost. They’re not available for public registration and can’t be used as a production domain. If you’re developing new software or a website, using this TLD to test it before launching it to the public can be helpful.
Infrastructure Top-Level Domain
Infrastructure Top-Level Domains (TLDs) are used for technical infrastructure purposes like reverse domain name resolution. They’re not available for public registration and are used only for internet infrastructure tasks. For example, .arpa is used for Address and Routing Parameter Area, .int is used for international treaty organizations, and .root is used for the DNS root zone.
Do Top-Level Domains Matter for SEO?
Country or region-specific TLDs (ccTLDs) often rank better in their respective local search results compared to generic TLDs (gTLDs).
While having keywords in your TLD doesn’t directly boost rankings, the choice of TLD can affect user perception and trust.
Certain TLDs, such as .xyz or .biz, may be associated with spam or less credible practices, potentially impacting the reliability seen by users.
How to Choose the Right Top-Level Domain for Your Website
Choosing the right top-level domain is important for your website’s success and visibility. Follow this guide to help you select the best TLD that matches your website’s purpose and target audience:
- Consider Your Website’s Purpose—Think about the main goal of your website, whether it’s commercial, informational, or focused on a specific industry. Choose a TLD that reflects your website’s purpose, such as .com for a commercial site or .org for a non-profit organization.
- Target Your Geographic Audience—If your website targets users in a specific country or region, consider using a country code TLD (ccTLD) like .us for the United States or .uk for the United Kingdom. This can help improve your website’s local search rankings and relevance.
- Research Availability and Restrictions—Some TLDs have eligibility requirements or restrictions. Ensure the TLD you choose is available for your website and that you meet any criteria needed to register it, such as being an educational institution for .edu or a government agency for .gov.
Benefits of Choosing The Right Top-Level Domain
Picking the right domain for your website is important. A top-level domain that matches your business or brand has many benefits. Here’s why using a TLD is good for your website:
- Establishes Credibility and Authority—For 75% of people, a company’s credibility is influenced by its website. This is why having a custom TLD can increase your brand or business’s credibility and authority. It shows your audience that you value your online presence and are dedicated to creating a strong brand.
- Boosts Brand Recognition—Choosing a TLD that fits your brand or industry can help people remember your website and boost its visibility. This attracts more visitors and engages them with your brand.
- Improves Search Engine Rankings—A domain that matches your industry or location can help you appear higher in search results. Choosing a ‘.com’ TLD is common. It’s the most popular top-level domain with 161.3 million domain name registrations.

The Future of Top-Level Domains
In the future, top-level domains are expected to continue to evolve. Here are some potential developments we may see:
- Expansion of TLDs—As the internet continues to grow, more TLDs will likely be added. This means website owners will have more options to choose from, but it may also make it more difficult to select the right TLD for their website.
- Localization of TLDs—TLDs may be tailored to specific regions or countries, making them more meaningful to local users. This could boost visibility and relevance for businesses in those regions, but it may also make the domain name system more complicated and pose challenges for website owners aiming for a global audience.
- Integration with Emerging Technologies—TLDs may integrate with emerging technologies like blockchain and the Internet of Things (IoT). This could open up new opportunities for businesses but may also bring challenges in standardization and compatibility.
