When should you choose .io?
.io is a country-code extension also used by technology projects. It may suit an app or professional tool when the full name is easy for its audience to understand.
A practical example
For an API or software product, one domain can bring together the product website, documentation and terms. Use descriptive paths instead of creating unnecessary domains.
Before you register
Review your budget over several years and the extension’s current policies. Choosing .io does not automatically improve search rankings or make a name memorable.
Before confirming registration
A search does not reserve a name. Check spelling, registrant details and the registration period. Registration is confirmed when the provider completes the operation. Read the terms of service y el privacy notice.
If you already own the domain, review how to prepare a transfer. For help choosing a name, read our practical guide.
