Why do I need a .io domain name?

Memorable

Have you ever noticed how many words end with “io”? There’s portfolio, studio, audio, and cheerio to name a few! .io domain names are great for wordplay, and give brands an opportunity to get their name in a shorter website address.

Relevant

To the tech and software development world, “io” is a common industry term so it speaks directly to that audience. However, .io domain hasn’t always been used by the tech industry. It wasn’t until recently that .io domain began trending for input/output, that it really took off.

Shorter Names, Greater Availability

When it comes to domain names, the fewer characters the better. An advantage of .io doman is that it is only two characters long instead of traditional top-level domains like .com. Since not everybody is an early adopter like you, there are many great domain names still available!

Some examples of .io sites already seeing the benefits!
