Frequently Asked Questions

Frequently Asked Questions about Domain Extensions

Helpful answers to common questions about checking username availability, domain extensions, and registration.

What is a TLD (Top-Level Domain)?

A Top-Level Domain (TLD) is the final segment of a domain name located immediately after the last dot (such as .com, .io, or .ai). It is managed by registries under the supervision of ICANN.

What is the difference between gTLD and ccTLD?

gTLDs (Generic Top-Level Domains) like .com, .org, and .net are open globally without geographic restriction. ccTLDs (Country Code Top-Level Domains) like .uk, .de, or .in are designated for specific nations, though some (like .io, .ai, and .co) are used globally.

Does domain extension affect Google SEO rankings?

Google treats all generic top-level domains (including .io, .ai, .dev, .tech) equally from a ranking perspective. However, ccTLDs (.de, .ca) provide localized geo-targeting signals to search engines.

Why do some extensions like .ai and .io cost more?

Registry pricing, operating fees set by national registries, and premium market positioning determine wholesale prices. Extensions with high commercial demand (like .ai) command higher annual renewals.

Are .dev and .app domains secure by default?

Yes, Google-operated TLDs like .dev and .app are included on the HSTS preload list, meaning modern web browsers will refuse to connect to them without valid HTTPS SSL certificates.
