What can a .io domain do for you?
Your domain name is more than just a website address…
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
These days, 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.
Be cutting-edge
When you use a .io domain name, you’ll never blend into the crowd. 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 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 use a number, consider registering a domain for each format.
Keep it simple
A domain name is the first thing people see when they find your site. So keep it short, sweet, and easy to type in a rush.
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.
