Planning guide

How to choose a domain name for your business — and mistakes to avoid

HostSmart.blogUpdated June 2026

The short answer

Your domain name is your permanent address on the internet. Get it right and it reinforces your brand every time someone visits. Get it wrong and you're either stuck with something awkward or facing the expensive, disruptive process of rebranding later. Here's what actually matters — and what most guides get wrong.

Choosing a domain name feels like a small decision. It isn't. Your domain is the address people type to find you, the identifier that appears in every email you send, and part of your brand identity for as long as your business exists. It's worth spending an hour getting it right rather than five minutes getting it wrong. Here's the honest guide.

The rules that actually matter

1

Keep it short

Shorter domain names are easier to type, easier to remember, and less likely to be mistyped. Aim for under 15 characters if possible. Under 10 is ideal. The domain name itself — not counting the extension — should be as brief as your brand allows.

Make it easy to say out loud

If you have to spell out your domain name every time you mention it in conversation, it's too complicated. Test it: say it to someone who hasn't seen it written. Can they type it correctly without asking you to repeat it? If not, reconsider.

3

Avoid hyphens and numbers

Hyphens are confusing when spoken aloud ("is that a hyphen or an underscore?") and associated with spam sites by some email filters. Numbers create ambiguity — is it the numeral 4 or the word "four"? Avoid both unless your brand specifically uses them.

Use your business name as the base

Your domain should match your business name as closely as possible. This makes it easy for existing customers to find you and reinforces your brand. If your exact business name isn't available, try a simple variation — adding your city, your service, or a descriptive word.

Check it's not already trademarked

Before registering, search the name in your country's trademark register. Using a domain name that infringes on an existing trademark can result in legal action and forced rebranding — regardless of who registered the domain first. A 10-minute check now prevents a very expensive problem later.

Which domain extension should you choose?

The extension is the part after the dot — .com, .co.nz, .com.au, .co.uk. Here's the honest picture:

.com.au
Australian businesses. Strong local trust signal for AU-based searches.
.co.uk
UK businesses. Well-trusted in the UK, less recognised internationally.
.net
Acceptable fallback if .com isn't available. Less preferred but widely recognised.
.io / .co
Popular with tech startups. Fine for the right brand — less intuitive for traditional businesses.
Our honest recommendation: Get both .com and your local country extension if budget allows. Register yourbusiness.com and yourbusiness.co.nz (or .com.au, .co.uk depending on where you are). Point both to your website. This protects your brand and captures visitors who try either version.

Common mistakes that haunt businesses for years

Mistake 1: Choosing a name that's too similar to a competitor

A domain name confusingly similar to a well-known competitor creates legal risk and sends the wrong visitors to your site. Check what your main competitors' domains are before registering anything similar.

Fix: Run a Google search for your intended domain name before registering it.

Mistake 2: Registering with a hosting company you might leave

Many businesses register their domain through whatever company they first used for hosting. If you later want to move hosts, transferring your domain can be complicated. Registering your domain separately from your hosting — or with a reputable registrar — gives you more flexibility.

Fix: Register domains with a reputable registrar like Porkbun, Namecheap, or directly through your hosting provider. Keep your login details safe — losing access to your domain registrar account is a serious problem.

Mistake 3: Letting your domain expire

Domains need to be renewed annually. If your registration lapses — even by a few days — your domain can be snapped up by domain squatters and held for ransom. Set your domain to auto-renew and keep your payment details current.

Fix: Enable auto-renewal immediately after registering. Add a calendar reminder 60 days before expiry as a backup.

Mistake 4: Using a keyword-stuffed domain instead of your brand

"bestplumbingservicesauckland.com" was a common SEO tactic in the early 2010s. Google no longer gives significant ranking advantage to keyword-heavy domain names, and they look unprofessional to customers. Your brand name — even if it's not keyword-rich — is a better long-term choice.

Fix: Use your business name. Build keyword relevance through your page content, not your domain name.

Mistake 5: Choosing a domain that limits your future growth

If you register "aucklandlawnmowing.com" and then expand your services to Wellington, or to garden design, or to other cities — your domain works against you. Think about where your business might be in five years before locking in a geographically or service-specific name.

Fix: Favour your brand name over descriptions of your current services. You can always explain what you do on the website.

Mistake 6: Not checking social media availability

Before registering your domain, check that the same name (or something very close) is available on the social platforms your business will use — Facebook, Instagram, LinkedIn. Consistent naming across your domain and social handles makes your business easier to find and looks more professional.

Fix: Use a tool like namechk.com to check availability across domain and social platforms simultaneously.

What if the domain you want is taken?

This is extremely common. The good .com domains are largely registered. Here's how to handle it:

Try a simple variation. If smithplumbing.com is taken, try smithplumbingco.com, getsmithplumbing.com, or smithplumbingnz.com. Adding "co", "get", "the", your city, or your country code often opens up options.

Try a different extension. If .com is taken, .co.nz or .com.au may be available and actually more relevant if you're targeting local customers.

Consider buying it. If the exact domain you want is taken but not actively used, the owner may be willing to sell. Many parked domains can be purchased for $200-500. For a domain you'll use for decades, this can be worthwhile.

Rethink the name. Sometimes not getting your first choice leads to a better brand name. Take the time to brainstorm alternatives rather than forcing a compromised version of your original idea.

Don't rush this decision. A domain name is genuinely hard to change later — your SEO history, backlinks, business cards, signage, and customer memory all attach to it. Spend a proper afternoon on this decision rather than five minutes.

Where to register your domain

You can register a domain through a dedicated domain registrar (Namecheap, Porkbun, GoDaddy) or through your web hosting provider. Both approaches work — the choice mainly comes down to convenience.

If you're signing up for web hosting at the same time, registering your domain through your host is the simplest approach. Bluehost includes a free domain for the first year with any hosting plan — so if you're setting up hosting and domain at the same time, you save $15-20 on your first year's domain cost.

Whichever registrar you use, keep your login credentials somewhere safe. Losing access to your domain registrar account is one of the most disruptive things that can happen to a business's online presence.

The bottom line

A great domain name is short, easy to say and spell, matches your business name, uses a trusted extension, and doesn't paint you into a corner as your business grows. Most businesses get this right with a bit of thought — the mistakes happen when people rush the decision.

Take the time. Check availability. Check trademarks. Check social handles. Register for at least two years. Enable auto-renewal. Then build something worth pointing it at.
