What can a .io domain do for you?

If you’re a tech company or startup looking for a domain, then registering a .io domain makes a lot of sense. It’ll show prospective clients who you are and what you’re about.

Keep it short and sweet

Originally a country code for the British Indian Ocean Territories, .io has since become a short, snappy domain that can be used by anyone. With high availability and no clunky spelling, a .io domain is the perfect choice for a unique project.

A tech-ready name

You’ll find .io domains all over tech projects, online games and more. Commonly standing for input/output, it’s a popular choice for organisations with a technical offering and is recognised as the go-to domain for startups and side hustles.

Join the tech scene

When you use a .io domain name, you’ll have a name that’s new, exciting and shows that you’re a brand that strives to be at the forefront of technological advances – and that’s got to be a good thing if you’re a tech company yourself!

How to choose a .io domain name

Struggling to decide on the best .io domain name? We’ve got some top tips to make your website stand out.

Size does matter

While your .io domain name can be up to 63 characters, shorter ones are easier to remember and harder to misspell.

Steer clear of numbers

Using numbers in your domain name can be confusing. If you need to, consider registering a domain for each format.

Keep it simple

A domain name is the first thing people see when they find your site. Keep your .io domain short, sweet, and easy to type.

Avoid special characters

Avoid characters like exclamation marks and underscores. And if you need to use a hyphen, don’t put it first or last.
