How to Choose a Domain Name: 10 Rules That Still Work

Knowing how to choose a domain name comes down to a few rules: keep it short and easy to say, make it brandable rather than generic, pick an extension your audience trusts, and check that nobody else has a claim to it. Your domain ends up on invoices, business cards, email addresses and every link people share, so a few minutes of care now saves a painful rebrand later.

This guide gives you ten rules that hold up in practice, a comparison of the main extension types, a pre-purchase checklist and the mistakes we see most often when people register their first domain.

Why your domain name matters

A domain is more than an address. It is the first thing people see in search results, the part of an email they use to decide whether to trust it, and the word they have to remember when they type it from a billboard or a podcast. A clear name raises click-through, reduces typos that send visitors elsewhere and makes your brand easier to protect.

Search engines do not reward exact-match keywords the way they once did. What helps SEO today is a name people recognise and click, plus the content and links behind it. Pick for humans first.

10 rules for choosing a domain name

1. Keep it short — aim for 6–14 characters before the extension. Shorter names are easier to type, say and fit on a logo.
2. Make it easy to say — use the radio test: if you say it aloud, can someone type it correctly without spelling it out?
3. Avoid hyphens and numbers — they are hard to communicate verbally and look less trustworthy. "5" or "five" is a question you will answer forever.
4. Be brandable, not generic — a unique word you can own beats a long string of keywords that sounds like everyone else.
5. Think long term — do not tie the name to one product, city or year if the business might grow beyond it.
6. Choose the extension on purpose — .com is still the default for global audiences; a country code builds local trust; newer extensions can say what you do.
7. Check trademarks — search the name in trademark databases and in the app stores. Registering someone else's brand can cost you the domain.
8. Check social handles — matching usernames on the platforms you use make the brand consistent.
9. Check the domain's history — a previously used domain may carry spam penalties or old backlinks. Look at archived versions before buying.
10. Register it quickly — good names go fast. If it passes your checks, buy it, and consider the closest variants and typos too.

Choosing the right extension

The extension (TLD) shapes how people read your domain. There is no universally correct choice, only a fit with your audience:

Some extensions have special rules: country codes may require a local presence, and a few TLDs such as .app and .dev require HTTPS for every site. Prices also differ a lot, especially at renewal. Our guide to cheap domain extensions compares the first-year and renewal costs.

How to come up with domain name ideas

If your first choice is taken, do not settle for an awkward variant straight away. Try these approaches:

• Combine two short words — an action plus a noun often makes a memorable brand.
• Add a short prefix or suffix — words like get, try, go, hq or app work when they read naturally.
• Invent a word — many strong brands are made-up words that are easy to pronounce.
• Use a different extension — the exact name may be free on a country code or a descriptive gTLD.
• Shorten the concept — remove filler words such as "the", "my" or "online".

Write down ten candidates, say each one out loud and ask two people to type them from hearing. The winner is usually obvious.

Pre-purchase checklist

• Spelled correctly, no accidental words when the letters run together.
• No trademark conflicts in your main markets.
• Clean history in web archives and no listing on spam blocklists.
• Renewal price known, not just the first-year offer.
• Extension rules met (local presence, HTTPS requirements).
• Matching social handles available, or acceptable alternatives.

Common mistakes to avoid

• Buying only the first year in your head. A domain is a recurring cost. Turn on auto-renew so it never expires by accident.
• Registering with a personal email you might lose. Use an account and contact you will still control in five years.
• Ignoring privacy. Without WHOIS privacy your contact details can end up in public lookups; see WHOIS privacy explained.
• Overthinking SEO keywords. A long keyword domain rarely beats a clear brand.
• Waiting too long. Names you have talked about publicly are often registered by someone else first.
