The .io domain extension has been skyrocketing in popularity for years<\/a>. Look at popular platforms like GitHub, GitLab, or Discord, and you’ll see it everywhere. This extension has evolved from an obscure country code to the go-to domain of startups and tech companies.<\/p>\n\n\n\n

\"TLD<\/figure>\n\n\n\n

But what exactly is .io? Why has it become so popular, especially among tech companies? And should you consider it for your site?<\/p>\n\n\n\n

In this article, I’ll tell you everything you need to know: from the origin of .io to the pros and cons, the costs, and who it’s worth it for. You’ll also learn how to register a .io domain and when you might be better off choosing a different extension.<\/p>\n\n\n\n

The origin of the .io extension<\/strong><\/h2>\n\n\n\n

Officially, .io stands for the British Indian Ocean Territory. It is a country-code top-level domain (ccTLD) that was assigned in 1997 to this small archipelago in the Indian Ocean.<\/p>\n\n\n\n

The area mainly consists of the Chagos Islands and has hardly any permanent residents. You’ll primarily find military personnel at the American base Diego Garcia. Not exactly what you’d expect behind one of the fastest-growing domain extensions in the world.<\/p>\n\n\n\n

The technical meaning is much more interesting. In computer science, “I\/O” stands for “Input\/Output” \u2013 the basis of how computers process data. A programmer sees .io and immediately thinks of data input and output. Perfect for tech companies, therefore.<\/p>\n\n\n\n

It is the latest example in a series of country-specific domain names that have grown into something completely different. Comparable to how .tv (actually from Tuvalu) became popular for video content, or .me (Montenegro) for personal websites.<\/p>\n\n\n\n

Why is a .io domain so popular?<\/strong><\/h2>\n\n\n\n

The popularity of .io didn’t appear out of nowhere. There are a few good reasons why tech companies and startups are flocking to it:<\/p>\n\n\n\n

Association with technology<\/strong><\/h3>\n\n\n\n

For anyone with even a little bit of technical background, .io immediately evokes associations with programming and software development. It gives your company instant tech credibility. No wonder SaaS companies, API services, and tech startups are eager to get involved with it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Availability of short names<\/strong><\/h3>\n\n\n\n

Try to find a short, catchy .com name for your startup. Chances are that everything that sounds good is already taken. With .io, you have much more choice. Names that have long been gone with .com are often still available with .io.<\/p>\n\n\n\n

Brand potential<\/strong><\/h3>\n\n\n\n

.io sounds short, powerful, and modern. It has a certain “coolness factor” that .com lacks. For startups and tech-focused companies that want to stand out from the traditional business world, that’s an advantage.<\/p>\n\n\n\n

Domain hacks<\/strong><\/h3>\n\n\n\n

A nice aspect of .io is how creative you can be with it. You can make the extension part of your brand name: portfol.io, stud.io, pied.io, and so on. These “domain hacks” create memorable web addresses.<\/p>\n\n\n\n

Disadvantages of a .io domain<\/strong><\/h2>\n\n\n\n

There are also a few disadvantages associated with using a .io domain.<\/p>\n\n\n\n

Price<\/strong><\/h3>\n\n\n\n

A .io domain costs significantly more than traditional extensions. While a .com domain costs around \u20ac10-20 per year, you often pay \u20ac40-100 per year for .io.<\/p>\n\n\n\n

Recognizability outside tech<\/strong><\/h3>\n\n\n\n

For a non-technical audience, .io is less familiar than .com or local extensions like .nl. Some people will automatically type .com after it.<\/p>\n\n\n\n

Ethical issues<\/strong><\/h3>\n\n\n\n

There is an ongoing discussion about the revenues from .io domain registrations. The British Indian Ocean Territory has a complex political history, with the original inhabitants (the Chagossians) being forced to leave. Part of the profits from domain sales flows to this controversial administration. It’s a point to be aware of, although it isn’t a deciding factor for most users.<\/p>\n\n\n\n

Who is a .io domain a good choice for?<\/strong><\/h2>\n\n\n\n

A .io domain isn’t suited for everyone. It works best in specific scenarios:<\/p>\n\n\n\n

Ideal applications<\/strong><\/h3>\n\n\n\n

Tech startups and SaaS products<\/strong>
If you are building a tech product, .io is a logical choice. It immediately communicates what kind of company you are.<\/p>\n\n\n\n

Open-source projects<\/strong>
Many well-known open-source projects use .io domains for their documentation and project websites.<\/p>\n\n\n\n

API documentation and services<\/strong>
For developers offering APIs, .io has almost become a standard.<\/p>\n\n\n\n

Crypto and blockchain companies<\/strong>
In the crypto world, .io usage is so widespread that it’s almost expected.<\/p>\n\n\n\n

Personal portfolios<\/strong>
Developers, designers, and other tech professionals often use .io for their personal websites.<\/p>\n\n\n\n

When it\u2019s better to choose something else<\/strong><\/h3>\n\n\n\n

Local businesses<\/strong>
If you’re targeting a specific region, like the Netherlands, then .nl makes much more sense. It gives local trust and has SEO advantages for local searches.<\/p>\n\n\n\n

Webshops for a broad audience<\/strong>
For e-commerce targeting consumers, .com is still king. It evokes more trust in online shoppers who aren’t tech-savvy.<\/p>\n\n\n\n

Traditional companies<\/strong>
If you’re not a tech company, .io may confuse your audience.<\/p>\n\n\n\n

How and where to register a .io domain?<\/strong><\/h2>\n\n\n\n

Registering a .io domain is not more complicated than other domains, but there are a few things to keep in mind.<\/p>\n\n\n\n

You need a domain registrar. For Dutch users, my.host is an interesting option. A big advantage is that .io domains here are about \u20ac20-50 cheaper than with many other providers.<\/p>\n\n\n\n

The advantage of a Dutch provider like my.host is that they often have more competitive prices than the large international registrars. Where you might spend \u20ac60-70 per year for a .io domain with some providers, you can often find it cheaper with Dutch specialists.<\/p>\n\n\n\n

Register your .io domain at my.host here. <\/a><\/strong><\/p>\n\n\n\n
