Frequently Asked Questions (FAQs)


Who can register a .io domain?

Anyone! There are no residency restrictions—any individual or business worldwide can secure a .io domain for their startup or project.

Is .io only for tech companies and developers?

Not exclusively. Although popular with tech startups, .io domains suit any business or creative project seeking a modern, innovative feel. They're widely adopted by e-commerce, education platforms, nonprofits, and creative professionals aiming to stand out.

Will a .io domain affect my SEO or credibility?

No. Search engines like Google treat .io domains the same as .com or .net. Your site's SEO and credibility depend on content and marketing, not domain extension. Plus, shorter and memorable .io names can boost click-through rates and word-of-mouth referrals.

Why are .io domains more expensive?

.io domains typically cost around $30-50/year due to their popularity among startups, making them a premium TLD. Compared to the high cost of acquiring premium .com domains, .io offers excellent value and brand differentiation.

Should I switch to .com later if my startup grows?

Not necessarily. Many successful startups stay with .io indefinitely, while others eventually acquire a .com and redirect it. Securing a .io domain now lets you launch quickly and affordably, without delaying your brand’s momentum.

How do I ensure my .io domain remains secure?

.io domains are secure and stable, managed by a reputable registry under ICANN oversight. Simply renew your registration on time, enable domain locking, and use two-factor authentication for added security.
