How to choose the perfect domain name

Your domain name needs to be short, memorable and relevant. It should tell customers who you are and what you do. Choose a .co.uk domain if you’re a UK business, or .com if you operate globally. Registering both will protect your brand name against abuse.

Key points for choosing a domain name

  • Try to keep it short and memorable
  • Pick one that includes your business name in it
  • Use .co.uk for a UK audience or .com for a global one
  • Register more than one to protect your brand name from abuse
  • Also register any common mis-spellings of your company name

How long should a domain name be?

There can sometimes be a tricky balance between getting a domain name that is too short, or one that is too long. Here are a few pointers:

  • It should be short enough for your customers to easily remember
  • It should be short enough to fit on your printed stationery or on the side of your van
  • It should be short enough that it’s not a mouthful when said out loud
  • It should be long enough to include your business name in it, to improve brand recognition
  • It should be long enough to tell potential customers who you are and what you do

A related factor to consider is whether it is easy to spell. Unless your business name and the way it is spelt is widely known, you should ensure that your domain name doesn’t contain words that could easily be mis-typed.

TIP: If your company name is often mis-spelt, consider registering both the correctly spelt and wrongly spelt domain names, to ensure you’re not missing out on any potential new customers.

How domain names affect SEO

A domain name is essential for customers finding you online, but unless you have the right domain name it may be hard for them to find your particular one amongst everyone else’s. The Internet is growing all the time so it’s important you stand out from the crowd and get found by the right customers. Here are some tips that will help you choose a domain name that boosts your SEO and online visibility:

  • If you’re a UK business targeting UK customers choose a .co.uk domain
  • If you have international customers or want to extend your reach, then pick a .com domain
  • If you only serve a specific city or area, then consider including it within the domain name
  • If you are in a particular trade (eg plumbing) then register a domain name that includes that word

Google will often use keywords from the domain to understand what your website is about and how relevant it is to location-based search queries. For example, if you’re a plumber in Guildford then having ‘guildfordplumbing’ in your domain name could cause your website to be displayed for users in Guildford that are searching for a plumber.

In short, to make yourself as visible as possible you need a domain name that is suitable for your market, as well as one that clearly shows who and where you are.

How the right domain name can help your brand

Consider the following: someone sees one of your vans going around town, they type your company name into Google and you’re not on there. That’s a potential customer you’ve just lost. Or what if, even worse, they type in your company name but end up on a competitor's website? That’s another company profiting from your hard work.

Here’s how to make sure your domain name helps your brand:

Register more than one

Register your domain name in as many relevant extensions as you can, in order to avoid a competitor doing so instead. A good starting point is to register .co.uk, .uk and .com. For any UK business, those are probably the three most essential ones.

Both .co.uk and .uk will showcase the fact that you’re British, and .com can introduce you to a wider audience. In some web browsers, if you don’t type in the domain extension, it will actually default to .com, so if you don’t have the .com you could be missing out there.

Remember — three domain names doesn’t mean three websites. You put your website on the primary domain (.co.uk if you’re a UK business) and then forward the other two there.

Register any common mis-spellings

If your business name is commonly mis-spelt, there’s a good chance your domain name will be too. Think about how people that aren’t familiar with your business might possibly spell it and make sure that you have a matching domain name.

There are many words in the English language that sound the same when said out loud but are spelt differently depending on the context. For example: ‘weather’ or ‘whether’; ‘buoy’ or ‘boy’; ‘pain’ or ‘pane’ etc. If your domain includes such a word, consider registering the alternative spelling as well.

Add a website and email

Registering the domain name is just the first step. You want to make sure that when people type it into their phone or computer there is something for them to look at. For this to happen you’ll need a website plan adding to the domain. It doesn’t need to be a top end one - even a basic website will do the job. It’ll let people know you’re open for business and give them a way of contacting you.

And with an email address as well, your contacts will see your domain name every time they receive an email from you. It’ll look far more professional and make a much more memorable first impression.

Your brand name is one of your most important business assets, so by protecting it online you’ll be securing it for yourself and making it work for you, whilst also denying it to others.

Legal checks before you register a domain

A key step that some businesses often overlook when registering their domain is whether it could infringe on any existing trademarks. This is important, as not doing these checks could open you up to costly legal claims.

You can search for a trademark on the government website, by entering relevant keywords or terms. Any existing trademarks that contain those words will be displayed to you. If the words you want to include in your domain name are very similar to an existing trademark, consider altering your domain name.

You should also try to avoid domain names that could potentially mislead or confuse customers. This could happen by making them think you are something you're not, or that you're associated with a well-known brand or person. Here are some examples:

  • If you're not a bank then avoid putting the word 'bank' in the domain
  • If you don't work with Amazon then don't have 'amazonservices' in the domain
  • Don't use names of celebrities or well-known public figures

In short, your domain name needs to be an honest representation of yourself or your business. It shouldn’t give a false impression, mislead people or attempt to capitalise on the brand power of a global company.

How can I check if a domain name is available?

Some of the best domain names are already taken, so it’s important to check if the one you want is still available. Here’s how:

  • Use a domain search tool (like the one below)
  • Make sure to check multiple extensions (such as .co.uk and .com)
  • If the one you want is taken consider varying it slightly, perhaps by changing its length or picking a different extension

Which domain extension should you choose?

With so many possible domain extensions, knowing which one to pick can be daunting. Here are our top tips:

  • Choose .co.uk if you’re a UK business or targeting UK consumers
  • Pick .com if you trade internationally or are looking to expand your reach
  • If you operate in different countries, consider choosing all relevant domain extensions – eg .ie for Ireland, .co.uk for UK, .fr for France, .nl for Netherlands etc, as well as .com
  • Protect your brand name from abuse by registering more than one extension. It’ll stop someone else from snapping them up and confusing your customers.

Video transcript: How to choose the perfect domain name

Your domain name does more than point to a website. It shapes how people find you, remember you, and decide whether your business feels trustworthy online. In the next couple of minutes, I'll show you how to choose a name that fits your brand, helps with visibility, and works for the audience you want to reach.

Start with the basics. The best domain names are short, easy to say, and easy to spell after hearing them once. If people might mistype your name, avoid anything clunky or consider securing common misspellings so potential customers still land in the right place.

Where you can, build the domain around your actual business or brand name. That makes the connection instant when someone sees your URL in search, social, or print. A close match between your company name and your web address is simply easier to remember, and easier to trust.

If most of your customers are in the UK, a .co.uk domain can signal local relevance straight away and feel like the natural fit for a British business. If you're aiming for a broader international audience, .com may suit that ambition better. The right extension should reflect where you want your business to grow.

A good domain can also give people extra context. For a local trade business, something like a plumber in Guildford is more informative than a vague brand name on its own. When the name hints at what you do and who you serve, it becomes easier for the right customer to understand your offer at a glance.

Once you've found a strong name, think about protecting it. Many businesses register more than one extension, like .co.uk and .com, so customers don't get confused. It's a simple way to strengthen your brand and reduce the chance of someone else building around a name that's already becoming yours.

And your domain doesn't just power your website. It can also give you a professional email address, which instantly looks more credible than a personal Gmail or Hotmail inbox. When your web address and email match, your business feels more polished, more memorable, and more established.

Before you commit, make sure the name doesn't clash with an existing trademark. The goal is a domain that clearly represents your business, not one that imitates someone else's.

Once you have a shortlist, the next step is simple. Use the names.co.uk domain search tool to check what's available in just a few moments. That lets you compare options quickly, spot the best fit, and move forward while your ideal domain is still there.

If you're ready to find the right name now, you can even register a free .co.uk domain to get started.

Choosing a domain name Frequently Asked Questions

  • How do I choose a good domain name?

    A good domain name should be:

    • Easy to remember
    • Short enough to write down
    • Including your brand name
    • Relevant to what you do
    • Suitable for your target market
  • How can I check if a domain name is available?

    You can check domain availability by using a domain search tool like the one at names.co.uk. You simply enter part or all of your desired domain, and it will perform a search to see if it’s available. If it isn’t, you’ll see some suitable alternatives that are available.

  • Should I include keywords in my domain name?

    It depends on the intended purpose for doing so. Having a keyword in your domain name will not enhance your search engine ranking for that keyword. However, it will clearly show to anyone who sees the domain exactly what you do. As long as the keyword sounds natural and is a good fit with your brand name then you could consider including it. Just be aware not to make the domain name grow too long – it still needs to be as memorable as possible.

  • What is the ideal length for a domain name?

    Your domain name will be getting printed on your business stationery or painted on the side of your company vehicle. You’ll be writing it down and telling it verbally to people. It’s important to make sure it isn’t too long. We would suggest a length of between 7 and 15 characters, as that is easy to remember and type.

  • Is .co.uk or .com better?

    It depends on your business model, as both .co.uk and .com have their own specific specialities. .com is more popular globally, but .co.uk is more widely used in the UK.

    • For a UK business, get .co.uk as your primary and .com as your secondary
    • For a global business that also trades in the UK, it would be the other way around
  • How do I choose the best business domain name for my startup?

    The best business domain name for a startup should be clear, memorable and aligned with your brand. To choose the right domain name:

    1. Start with your brand name or a variation of it
    2. Keep the domain short and easy to spell
    3. Choose a name relevant to your business or service
    4. Check availability across key extensions like .co.uk and .com
    5. Avoid complex words, hyphens or numbers

    A strong domain name helps your startup build trust, stand out and grow online.

    • Keep the name short and easy to type
    • Make sure it aligns with your brand and purpose
