.co vs .com: A Complete Guide to Two Popular Domain Extensions
Deciding on a domain name can seem overwhelming. The choice can significantly affect your brand and your business. What’s more, this big decision is further complicated by the fact that you also have to choose an appropriate domain extension.
There are many domain extensions available, but two of the most popular are .co and com. Ultimately, which one you settle on will depend on your unique needs. You’ll need to consider the scope of your business, your budget, and the available domain names that are well-suited to your brand.
In this article, we’ll explain what domain extensions are. Then, we’ll explore the differences between .co vs .com, and explain how to choose between the two. Let’s get started!
An Introduction to Domain Name Extensions
A “domain name,” or simply a “domain,” is a site’s web address. In the same way you might remember a close family member’s home address or phone number, you may be able to recall certain well-known domains easily, such as www.facebook.com.
These simplified web addresses are made possible by the Domain Name System (DNS). In a nutshell, the DNS connects a human-friendly domain to an IP address (here’s how to see your IP), so servers can display the correct web page to visitors. Some people refer to the DNS as the internet’s phonebook, because it enables users to look up a website without memorizing a long series of numbers.
Every domain has an ‘extension’ or Top-Level-Domain (TLD). This is the last part of the domain name. For example, the .com in www.facebook.com is the domain extension. While the majority of websites end in domain .com, there are actually dozens of other extensions you can choose from.
.co vs .com: Two Popular Domain Extensions
Since there are currently about 1.88 billion websites in the world, it’s only natural that there are several organizations that monitor TLDs. Perhaps the most important of these is the Internet Corporation for Assigned Names and Numbers (ICANN):
Thanks to these organizations, there are a set number of domain extensions you can use to build a new website. More are being added every day, but a handful of traditional options are still the most popular.
.com TLD was one of the original TLDs, implemented in 1985 along with other well-known options such as .org and .gov. It is the most common domain extension by a large margin and is in many ways synonymous with the internet itself. It’s understandable that a lot of internet users still assume that every site ends in .com.
On the other hand, .co has a more complicated history. It was created to be the country code TLD for Colombia. In other words, it was originally meant to be used specifically by websites and businesses located in that country.
However, this domain extension has changed hands a few times, and over the years has lost its restrictive nature. Now anyone can use it, no matter where they’re located, and it is no longer exclusively linked to Colombia.
In fact, these days you’ll often see .co referred to as an abbreviation for “company” or “corporation”. While nowhere near as popular as .com web domain , it has gained traction in recent years and is now used by almost 1% of all websites.
3 Factors To Consider When Choosing Between .co vs .com
Now, let’s go over some of the most important factors you may want to consider when choosing between .co vs .com. If you assess these three aspects carefully, you’ll be able to make a wise decision for your future website.
1. Availability
Both .co and .com are commonplace TLDs. However, .com significantly overpowers .co in terms of popularity. In fact, more than half of all global websites have a .com TLD, while .co doesn’t even make the top ten.
This data is useful, but it can also be misleading if you’re not looking at the big picture. For example, it’s important to note that .com websites are not on the list of new leading gTLDs (neither are .co sites). The most popular gTLD for new sites is .xyz.
Since .com extensions are finite, trendy domain extensions are constantly emerging. Unless you want a highly-unique domain name, chances are that pairing it with the .com gTLD may not be possible. On the other hand, the .co domain extension is more likely to be accessible:
Of course, if you do stumble upon a potential cheap .com web domain that you like and that is available, we highly recommend buying it just in case. If you know you won’t be able to use it for a while, you can always convert it to a parked domain until you’re ready.
