Domains explained: choosing your web address

By Pann Studio·5 min read·Updated 2026

Your domain is your address on the web — like yourbrand.com. It's the first thing customers type and remember, so it's worth choosing well. Here's everything you need in plain English.

1. What is a domain

A domain is the human-friendly name that points to your website, so people don't have to remember a string of numbers. You register it for a year at a time and renew to keep it.

2. Domain vs hosting

They're different things that work together: the domain is the address; the hosting is the land the house (your site) sits on. You usually need both — see hosting & SSL.

3. Which extension should you pick?

4. How to register

Register through a domain registrar, pay per year, and point it at your hosting. A .com typically runs about ฿350–600/year. Keep the account in your own name so you always own it.

5. Naming tips

Frequently asked questions

Do I own my domain forever?

You lease it yearly. As long as you renew (and it's registered in your name), it stays yours.

Is .co bad for SEO?

No — extension has minimal SEO impact. Choose for trust and memorability; .com is simply the most familiar.

Can I move my domain later?

Yes, domains are portable between registrars and hosts — another reason to keep it in your own account.
