.io domain FAQs
What does a .io domain mean?
A .io domain was originally the country-code extension for the British Indian Ocean Territory. Today, it’s commonly associated with tech, startups, and online tools, especially where “io” suggests input/output.
Is a .io domain trusted?
Yes. .io is a valid top-level domain that works in browsers, email, and search engines like other domain endings. It is managed through an official registry, so it behaves like a normal website address.
Is a .io a good domain?
Yes, if your project is tech-focused, product-led, or wants a modern, short name. Search engines treat .io like other extensions for SEO, so content and relevance matter more than the ending.
Should I choose a .io domain or .com domain?
Choose .io if you want a shorter, tech-oriented name or your .com option is taken. Choose .com if you want the most familiar extension for a broad audience and everyday recall.

Anyone can register a .io domain. It is not limited to people or businesses in a specific country, so eligibility is open.
