Your domain name is on every email, business card and link you share, and it is one of the few website decisions that is genuinely painful to undo. Changing it later means losing links, search rankings and the trust people have built with your old address. This guide shows you how to choose a name you will still like in five years, pick the right extension, and register it safely.
The short version: choose a short, easy-to-say name, avoid hyphens and numbers, check that the name is free everywhere your business will appear, register it in your own name, and switch on auto-renew and two-factor authentication.
What makes a good domain name
A good domain is easy to remember, easy to say and easy to type. Test any idea against these points:
- Short. Fewer characters mean fewer typing mistakes. Most strong names are two short words or one made-up word.
- Easy to say. Read it aloud to a friend. If they have to ask how to spell it, it is too complicated.
- No hyphens or numbers. People forget them, and they are easy to get wrong when you say the address out loud.
- Distinctive. A brandable name such as a coined word or an unusual pairing is easier to protect and remember than a string of keywords.
- Room to grow. A name tied to one service ("sydneylogodesign") becomes a problem when you add a second service or move city.
You do not need your main search keyword in the name. Search engines read the content of your pages, and a name that sounds like a brand tends to earn more links and repeat visits than one stuffed with keywords.
A quick way to brainstorm
- Write down three to five words that describe what you do, who you help and how you want people to feel.
- Combine them in pairs, shorten them, or use a word from a different language that fits.
- Shortlist five names, say each one out loud, and ask two people to type them from hearing alone.
- Check each shortlisted name using the steps below before you fall in love with it.
Choosing an extension
The extension is the part after the dot. For an Australian audience, the main options are:
- .com.au signals a commercial Australian business and is familiar to local customers. Under auDA's rules, a com.au name must be registered by a commercial entity and generally has to match or closely relate to your business, personal or trade mark name.
- .au (the shorter "direct" version) is open to a wider range of people and does not require an ABN, though you still need an Australian connection.
- .com is the most recognised extension worldwide and a safe default if you plan to serve an international audience.
Whichever you choose, every .au name requires an Australian presence, and you must keep meeting it for as long as you hold the name. Check the current rules on auDA's Australian presence page before you register, because your registrar will verify it. A country extension also tells search engines the site is meant for that country, which suits a local business and is less ideal if your customers are mostly overseas.
Newer extensions (such as .studio or .shop) can work when the name reads naturally, but test them on real people. Many will still type .com out of habit.
Check the name before you buy
- Availability everywhere. Search the name on the social platforms you plan to use, so your handles match your address.
- Trade marks. Search the Australian trade mark register (and your other markets) so you do not build a brand on a name that someone else owns. A trade mark search takes a few minutes and can save you from a forced rename.
- History. A domain that has been used before may have a poor reputation for spam, which can hurt email delivery. Look it up in a web archive and a spam check before you buy a second-hand name.
- Similar spellings. Consider whether a competitor owns a near-identical name that could confuse customers.
Register it safely
- Use a reputable registrar and read the renewal price. Introductory first-year prices are often much lower than the ongoing price, so compare the cost over several years.
- Register in your own name or your business's name. Never let a web designer or agency register the domain under their own account. If the relationship ends, you can lose control of your address.
- Turn on auto-renew and keep a valid payment card on file. An expired domain can be bought by someone else.
- Enable two-factor authentication on the registrar account, and use a unique password stored in a password manager. Whoever controls this account controls your website and email.
- Use contact details you can access long term, such as a role-based email address, so that renewal and transfer notices do not get lost when staff change.
- Keep domain and hosting separate. Registering your domain with one company and hosting with another makes it easy to switch hosts later. Read how to choose web hosting when you are ready to pick a home for your site.
After you register
- Point the domain at your host, and set up your email addresses on the new domain.
- Register obvious variations if they are cheap, and redirect them to your main name.
- Add a calendar reminder for the renewal date, even with auto-renew on.
- Consider registering your name with a common alternative extension, to stop others from using it.
Questions people ask
Does my domain name affect my search rankings?
Not directly in a big way. Search engines focus on the quality and relevance of your content. A clear, memorable name helps indirectly because people trust and link to it more.
Should I include my city or my main keyword?
Only if you are sure you will never expand. A location or service in the name can box you in, and a distinctive brand is usually a better long-term choice.
How long should I register a domain for?
You can usually register for one to several years at a time. Longer terms can lower the risk of a missed renewal, but check the price for each term first.
Can I change my domain later?
Yes, but it takes work. You would move the site, redirect every old page to its new address, and tell customers and search engines about the change. Choose carefully so you do not have to.
