How to Choose a Domain Name for Your Business

Why your domain name actually matters

Your domain name is your address on the internet. When someone wants to find you online, they'll either Google your business name or type it directly into their browser. If your domain is confusing, hard to spell, or doesn't match your business name, you'll lose customers before they even get to your website.

The good news: choosing a domain is something you can do in an afternoon, and it doesn't have to be expensive. The tricky part is that good names go quickly, so you'll need to move fast once you find one you like.

The golden rules for domain names

1. Keep it short and simple

Shorter is almost always better. Aim for under 15 characters if you can. The easier it is to type, the fewer mistakes people will make. If your domain name takes three goes to spell correctly, it's too complicated.

2. Use your business name

If possible, register a domain that matches your business name exactly. This builds brand consistency and makes it obvious to customers where they've landed. If your exact name is taken, that's a problem worth solving (more on this below).

3. Avoid numbers and hyphens

Numbers and hyphens make domains harder to remember and harder to say out loud. If someone hears your business name on the radio, they shouldn't have to guess whether it's "2" or "two", or wonder where the hyphen goes. Keep it letters only where you can.

4. Use .co.uk or .com

If you're a UK business, .co.uk shows you're local and builds trust with UK customers. .com works globally and is more recognisable, but it can feel less local. Unless you have a good reason, stick with one or the other. Avoid unusual extensions like .london or .shop — they're harder to remember and some customers won't trust them.

5. Say it out loud

Before you register anything, say the domain name out loud to a friend or family member. Can they spell it back to you correctly? If not, it's probably not the right one.

Step-by-step: how to actually choose one

1. Check what's available. Go to a domain registrar like GoDaddy, Namecheap, or 123-reg and search for your business name with .co.uk. Make a list of 5–10 options you like.
2. Check social media handles too. You want your Instagram, Facebook and LinkedIn handles to match your domain where possible. Check these are available before you commit to a domain name.
3. Make sure it doesn't sound like another brand. Google your shortlist to see if any of them sound too similar to established companies. You don't want confusion.
4. Pick your top choice and register it. Register for at least two years — this is cheaper per year than registering annually, and it gives you breathing room if you're busy.
5. Consider registering 2–3 similar alternatives. If you have budget, grab variations like the hyphenated version or the .com version, even if you don't use them straight away. This protects your brand.

What if your ideal domain is taken?

This happens more often than you'd think, and it's frustrating. Here are your options:

• Try a different business name. If your domain is a perfect fit for your brand, this might be worth considering. You're choosing a name you'll use for years, so get this right early.
• Add a descriptor. Instead of 'jonesplumbing.co.uk', try 'jonesplumbinguk.co.uk' or 'myjonesp lumbing.co.uk'. It's a bit longer but still clear.
• Contact the domain owner. If a large corporation is sitting on your domain, they're probably not interested. But if it's someone else's small business, you can sometimes negotiate to buy it. Expect to pay £100–£1,000 depending on how desirable the name is.
• Use a different extension. If .co.uk is taken, .com might be available. Just pick one and stick with it consistently.

The honest truth: it's not always perfect

You won't find a domain that ticks every single box. Most domain names involve some compromise — maybe it's slightly longer than ideal, or you had to add a word you didn't plan for. That's normal. What matters is that it's professional, matches your business name reasonably well, and is easy for customers to type.

Don't spend six months trying to find the perfect domain. Spend a few hours, pick something sensible, and get your website live. You can always rebrand later if you need to, though it's a hassle.

After you've registered: what's next?

• Set up email addresses using your domain (jane@yourcompany.co.uk looks far more professional than jane@gmail.com)
• Make a note of the login details somewhere safe — you'll need them when you build your website
• Turn on auto-renewal so you never accidentally let it lapse
• Register similar domains if budget allows — protect your brand
