Owing to multi-layered benefits, it comes as no surprise that 359.8 million domain names were registered in 2023! If you’re in the process of setting up a website and want to choose the perfect domain name extension, this guide is for you.

We’ll explore everything you need to know about domain name extensions, from why they are important to how to choose the right oneLet’s go!

What Is Domain Name Extension?

A domain name extension is the part of a URL address that comes after the last dot—technically known as top-level domains (TLDs). It typically indicates the type or purpose of the website. Here are some examples of common domain extensions:

  • .com — One of the most widely recognized domain name extensions for commercial websites
  • .org — For non-profit organizations or informational websites (not intended for commercial use)
  • .net — For tech companies or other network-related websites
  • .co — A shorter version of .com that speaks directly to a younger audience

When you add the second-level domain (SLD) or website name (the unique name chosen by the website owner) to the domain name extension, you get the complete website address. An example of this would be

5 Types of Domain Extensions You Must Know About

Domain extensions help categorize websites by type. Here are the five most common ones in use:

1. Generic domain extensions (gTLDs): Most people are familiar with generic top-level domains such as .com, .org, .net, and .info. The advantage of using this domain extension type is that anyone can use it—irrespective of the location or country of operation. So, if you need a global website, a gTLD is a good fit.

2. Sponsored domain extensions (TLDs): These top-level domains are sponsored by a specific organization or a community and are not used by the general public. They indicate a specific purpose or affiliation. Some examples include .gov for government websites, .edu for educational institutions, .mil for U.S. military websites, and .int for international organizations (WHO, for instance):


If you want to register your domain name extension, such as .motorola, for instance, the Internet Corporation for Assigned Names and Numbers (ICANN) now allows you to do so under the brand TLD category.

3. Country code domain extensions (ccTLDs): These domain extensions are assigned to specific countries and indicate a website’s geographic location. Some examples include .uk (United Kingdom), .ca (Canada), and .jp (Japan). Naturally, this type of domain name extension is ideal if you want to target a specific audience in a particular country or region.

Remember that the ccTLD rules will differ for each country, so check the rules before you apply. Some countries allow the general public to use ccTLDs, whereas some countries only allow government agencies to use them.

4. Restricted domain extensions: Some generic URL extensions have restrictions, meaning users wanting to use them need to register first. For example, only U.S. government agencies can use .gov, and .jobs is limited to job listing websites. We recommend consulting with a domain specialist to help you get a valuable and meaningful domain extension.

5. Special use domain extensions: ICANN reserves certain domain name extensions for specific technical purposes. For example, extensions like .local and .test are reserved to curb confusion or misuse.

Why Are Domain Extensions Important?

We’ve laid down the basics. Let’s now understand why domain extensions are important.

1. Right domain name = instant recognition

Your domain extension holds the power to ensure top-of-mind recall.

Domain extensions influence why visitors will visit your website. The popular ones boost familiarity and recognition, so people trust them by default. To make the most of your domain extensions, choose one that is:

  • Most active in your industry
  • Aligns with your brand’s personality
  • Maps to your customer’s expectations

2. Right domain name = greater trust = positive first impression

First things first know that domain name extensions help gain trust from the customer and create a positive impression. It also represents your branding in a more professional light. For instance, visitors would be more likely to click a website with a .com. extension than a .zip extension.

3. Right domain name = improved website categorization

Depending on your website and niche audience, a domain name extension categorizes your site using country code or sponsored TLDs as markers. By extension, you’ll be able to attract the right kind of target audience to your website.

Moving on, let’s address the elephant in the room:

“Does Domain Extension Affect SEO?”

The short answer? No.

Contrary to popular opinion, newer TLDs like .space are as credible as compared to .com in the eyes of Google when it comes to SEO—according to John Mueller, a Search Advocate at Google.

This means that your choice of domain extension is not a direct ranking factor in Google’s search algorithm. Instead, Google focuses on the relevance, quality, and authority of your website content when determining search rankings.

6 Most Common Domain Extensions: An In-depth Lowdown

Familiar domain extensions feed credibility and trust. Here are six common domain extensions you can choose from:

1 .com — Most popular choice for businesses

It is true that .com is the most trusted domain extension and, unsurprisingly, the most popular top-level domain as well, with 46% of global websites using it:


For-profit commercial businesses mostly use this domain extension. Considering humans are driven by habits, it makes sense to opt for this domain extension and capitalize on this extension’s popularity.

Think about it – we associate all websites with the .com domain extension because we’re most accustomed to seeing it. So, if your website wants to cater to a global audience and improve its footprint quickly, .com is your best bet.

Sometimes, you may have typed in a website’s domain extension as .com only to realize it’s .co. This kind of mistake is common and demonstrates the influence .com has on visitors today.

Even hackers are buying .com domain extensions with slightly misspelled domain names to deceive unsuspecting customers and engage in fraudulent activity.

If the cost of .com does not fit your budget, don’t worry. There are other options you can select from.

2 .co — A shorter, newer version of .com

Want to validate your website immediately with a fresh and original domain extension? Use the .co domain extension, a popular choice for global domains today.

In the visitor’s eyes, .co could stand for company, corporation, or commercial business. However, is a forward-thinking startup that targets early-stage startups and wants to cater to a younger target audience:


In this case, .co presents a sleek and modern image and is best suited for the brand’s intended target audience (a younger demographic).

While not as popular as .com, .co is gaining recognition and is a great choice for those who want a shorter, newer domain extension.

3 .net — Great for tech companies

This domain extension is open to all users and is a great alternative to the .com domain extension. Short for network, this extension translates to all-things technology. So, if you’re in the tech space, it’s worth looking into this domain extension. If not, stay away, or else you risk confusing customers with your product, as most visitors associate .net with strictly tech-based services.

If you need more proof, know that global brands like Behance (, SlideShare (, etc., use .net. Moreover, since .net is not as in demand as .com, you won’t have to compromise with your domain name as shown below:


Since Artelogic is in the IT space, it makes perfect sense to use this domain and build credibility within the tech community.

4 .gov — Best for government agencies

When it comes to establishing trust and authority, nothing beats the .gov domain extension:


A .gov domain is reserved exclusively for government agencies and instantly conveys credibility and reliability. It’s the gold standard for government entities looking to build a strong online presence.

5 .edu — Ideal for educational websites

As you might have guessed, .edu instantly lets the visitor know that your website is educational, as the Harvard website highlights below:


If your website is dedicated to learning and knowledge sharing, the .edu domain is the perfect choice.

Recognized worldwide as a symbol of educational excellence, a .edu domain lends instant credibility to universities, schools, and other educational organizations.

6 .org — A go-to choice for NGOs

One of the original TLDs, along with .com and .org, was created for non-profit organizations, though anyone can use this domain extension today. It is also actively used by political parties, online communities, and non-governmental organizations.

A word of caution: People associate .org as an educational and trustworthy site; therefore, it does not fit into the commercial big picture. For example, you’ll be hard-pressed to find eCommerce stores with a .org extension. In terms of SEO ranking, .org holds the same importance as .com.

Generally speaking, people also associate .org with knowledge bases like Wikipedia:
