Choosing the right domain extension for your site’s purpose and identity can make all the difference in terms of its success.

The History of Domains

Domains have existed since 1983, even though the internet did not become a household utility until the 1990s. Even yet, they weren’t available for public registration until 1986 via the Domain Name System (DNS).

Thanks to increased rules that allow people and organizations to form their own domain extensions, what started with only a few domain extensions has now grown to include hundreds of top-level domains (TLDs).

Domains were created as a remedy to a previously difficult method of accessing a website, which required entering a set of numbers that were nearly impossible to remember. Domains are now a must-have for internet browsing, allowing us to remember our favorite websites by simply typing the domain name into the address bar of our browser.

Categories of Domain name Extension

Your domain registrar can help you identify almost any domain extension, but not all domain extensions are created equal or are relevant to your needs. When choosing on the correct extension for your website, it’s useful to know the differences between domain extensions

  • Generic Domain Extensions (gTLDs): A generic domain extension (gTLD) is a sort of TLD, or domain extension, which is also known as the last portion of a domain name. Generic domain extensions include some of the most popular choices, such,.net,, and always have at least three letters after the dot. These extensions are available to anyone.
  • Restricted Domain Extensions (RDEs) are generic top-level domains (TLDs) that have special registration conditions. For example,.gov is exclusively open to government bodies and agencies in the United States, is only open to websites that provide job vacancies or job advertisements.
  • Country Code Domain Extensions (ccTLDs): Each country has its own set of country code domain extensions (ccTLDs). For example, Thailand’s extension, while the United Kingdom’s extension Although some nation extensions are only available to citizens, businesses, or organizations from that country, the majority of registrants can use them.
  • Domain Extensions for Special Purposes: This category includes extensions like.test and.local, which are limited to certain technical applications. These extensions are maintained by the Internet Assigned Numbers Authority (IANA), which precludes them from being registered openly using the DNS.

What to Look for When Choosing a Domain Extension

While there are numerous domain extensions to pick from, you should exercise caution while selecting one for your website. When determining which domain extension to use, keep the following criteria in mind.


Your domain directs all visitors to your website, which reflects your brand. As a result, your domain name is an extension of your website that must be considered as part of the overall picture. You’ll need to use some human psychology in this section.

Consider a handful of your favorite websites. What are their ramifications? Is the entire domain name, including the extension, visually appealing? Do the extensions make you think, “This site is reliable”?

People that come to your site via a search engine notice your domain name. A domain such as appears to be more reliable than Why? is the most well-known domain on the internet, we’re more familiar with it, isn’t used nearly as frequently. Our minds are partly conditioned to domains more recognizable, trustworthy, and aesthetically pleasant after years of internet usage.

Other domain extensions, such, are similarly affected. When it comes to branding, using one of the more common domain extensions is usually the best option. Having a recognizable domain extension can make your domain name more memorable.

SEO stands for “search engine optimization” (SEO)

According to Google, having a non-standard domain extension has no bearing on your site’s SEO. True, your domain extension has no bearing on where your site appears in Google’s search results. It may, however, have an indirect effect on your SEO.


Taking a step back from what we discussed about branding and trust, your domain name may not be as enticing as others when it appears in search results. Let’s say one of your pages has the domain and another has the domain Based on what we know about domain trust and familiarity, more people may prefer version.

Similarly, is becoming a popular extension for apps and tech-related sites, a mobile app with a domain like may perform better in search results than one with As a result, your domain extension may have an indirect impact on your SEO.

The Goal of the Website

Another important thing to consider when picking a domain extension is the aim of your website—personal, educational, business, and so on. Most nonprofit organizations, for example, because it gives them a known credibility element while still distinguishing them from educational institutions and government entities.

If you have an internet business, you may want to consider .co, as both have become well-known for commercial use. Informational sites, such as tutorial or research sites, should use domain to make it clear what the site’s aim is before anyone even clicks on the domain.


The location of your business may influence the domain extension you choose, especially if your target market is also in the same area. If customers looking for your business are likely to seek a company like yours in your geographical location, a ccTLD can help.

Assume you were looking for “auto repair Scotland.” Your website address is Even though you’re in Scotland, your site is unlikely to appear in the search results because its extension doesn’t trigger geographical specifics. You’d have a better chance of appearing in that person’s search results if your domain was

Domains: Old vs. New

Domain names are now divided into two categories: old school and new school. Old school domains, such,.net,, are the originals. New school domains are those that were added after the first list of extensions was issued, such as those released as part of ICANN’s TLD update in 2013 and later. Extensions like .info, .earth, .movie, and .health are among them.

As can be seen, new domains are frequently far more specific than older names. These can assist people to understand what your site is about even before they get at your page, but they lack the trustworthiness of the more established older domains.


Extensions are priced differently by domain registrars. The current popularity of the extension, who generally purchases the domain, and how new the extension is all influence pricing. Because tech companies commonly snare extensions like .io, .ia, and .tech, they’re more expensive than .com and .net. Similarly, .inc is one of the most expensive, as it is typically purchased by incorporated businesses.

The most affordable generic TLD is .com, which is followed by .net, .org, and .co. Of course, the domain you’re purchasing could be worth thousands of dollars if it was purchased from a registrar for a high price. In general, older domains will have lower pricing, but the number of available domain names will be limited.

The Top 10 Domain Extensions and Their Uses

The ten domain extensions listed below are among the most popular today and are not restricted in their use. We’ll look at the most popular usage for them and when switching to a different extension can be a better option.

Networking sites and online communities, like internet-based “networks,” nonetheless find it useful to identify their purpose.

.Org domain, which stands for “organization,” is frequently assigned to a nonprofit or public organization, community, or group. The extension is also used by local public businesses such as libraries and chambers of commerce.

Io is becoming a more common alternative for mobile and computer app landing pages and websites. .io is also popular among tech-related websites, particularly among startups. If you have a business name that matches well with this extension, such as or, it’s also one of the most fun to play with.

While .io is becoming more well-known in the IT and gaming industries, it may be unfamiliar to others who do not follow such fields. Furthermore, because domains are now based on foreign languages, public trust in the extension may be shaky.

It’s also the first domain to offer internationalized domain names and the first to use more than three letters (IDNs).

It’s preferable to utilize this addon only if you’re confident that your website has useful content. Otherwise, you risk losing visitors who had hoped to see it.


The .inc domain has grown in popularity as a viable alternative to the,.net, domains. This extension is typically used by incorporated firms, however, it is available to everyone.

For example, Intuit QuickBooks offers free QuickBooks Online Simple Start for .inc domains, while 99Designs offers free Power Packs and savings on logo design. LegalZoom even offers a free business creation service.

The advantages of having a .inc for a company are numerous, but they come at a price.

Another business-oriented domain is.

Icu is an internet abbreviation that stands meaning “I see you.” Although you may not encounter this extension very often on the web just yet, it is one of the more popular newer domain name options.

Conclusion: The Best Option Is Still.Com
