Why
Why choose a .io domain
Somewhere along the way .io stopped being a country code and became the badge of tech startups: it reads as input/output, it frees up thousands of names taken on .com, and investors and developers see it as completely normal for a main address.
Google treats .io as a generic TLD, so it ranks worldwide rather than being tied to one country — you get the tech identity without any geographic penalty.

FAQ
.io domain questions
How much does a .io domain cost?
Registering a .io domain costs $39.99 for the first year and renews at $47.99/yr — both figures are shown side by side before you pay, so there are no year-two surprises.
Is .io okay for a serious company's main domain?
Absolutely — thousands of funded startups and public tech companies use .io as their primary address. In software, it's as unremarkable as .com.
Why is .io more expensive than .com?
The .io registry sets a higher wholesale price than the giant gTLD registries. You're paying for scarcity and brand cachet; the renewal price is shown up front so there are no surprises.
Does .io only rank in one country?
No — Google classifies .io as a generic TLD, so it targets globally exactly like .com, and you can set geo-targeting yourself in Search Console if you want a specific market.
