Domain Names Explained for Small Businesses

Updated: 30 October, 2026

Your domain name is your business's address on the internet: the bit people type to reach you, such as the name in an email address or on a van. It sounds simple, but a few choices made on day one, especially who registers it and where, can cause real headaches years later. This guide explains the basics in plain English for business owners in Liverpool and Merseyside who are planning a website.

What is a domain name?

Every device on the internet has a numeric address, called an IP address, which works a bit like a postal address for routing data. Numbers are hard to remember, so the Domain Name System (DNS) lets us use names made of letters, numbers and hyphens instead. ICANN, the organisation that helps coordinate these unique identifiers worldwide, explains this in its beginner's guides.

A domain name is not the same as hosting. The domain is the address; hosting is the place where your website's files live. You need both, and they can be bought from different companies. Our guide to how long it takes to build a website shows where domains and hosting fit into the project.

Choosing a good domain name

• Keep it short and easy to say. If you have to spell it out on the phone, it is too complicated.

• Use your business name where you can. People searching for you will expect it.

• Avoid hyphens and numbers. They are easy to mistype or forget.

• Check it does not clash with another business. Search for the name and look at social media handles too.

• Think about a .co.uk or .uk. For a business serving customers in the UK, these are familiar and trusted-looking, though .com is also fine.

Do not worry about stuffing keywords into the name. Google's published guidance on spam policies does not treat a keyword in your domain as something that earns a boost, and it specifically warns against buying expired domains to manipulate rankings. As always, nobody can guarantee rankings: a sensible, memorable name is a better investment than a clever one.

Who owns your domain? Check the registrant

When you register a domain, the person or organisation named as the registrant is the one on record as holding it. The registrar is the company you buy it through. ICANN describes the relationship between registrant and registrar in its page on registrars, and for .uk names Nominet's registrant terms say the registrar acts on the registrant's behalf in creating and maintaining the domain.

In practice, this means you should:

• Register the domain in your business's name, not in your web designer's or a former employee's.

• Use an email address you will still control in five years, ideally a shared one rather than one person's inbox.

• Keep the login details for the registrar account somewhere safe, and know who else can reach them.

If you are choosing an agency, ask the question directly. Our guide to choosing a web design agency in Liverpool lists ownership and access among the questions worth asking before you sign anything.

Domains are rented, not bought outright

You do not buy a domain forever. You register it for a set period, often one year or more, and then renew it. If a renewal fails, because a card has expired or reminders go to an old email address, the domain can lapse and your website and email can stop working. Renewal terms and any grace period vary between registrars, so check your own registrar's policy.

Practical steps:

• Switch on auto-renew, and keep the payment card up to date.

• Put the expiry date in a shared calendar.

• Make sure reminders go to an inbox someone actually reads.

What a domain does besides your website

Your domain also powers your email addresses (such as name@yourbusiness.co.uk), which look more professional than a free webmail address. At Outible, extra email addresses are £1 a month each, and hosting is £25 a month for the Simple website (£1,500, up to 10 pages) and the CMS website (£2,000).

Behind the scenes, DNS records tell the internet where to send visitors and where to deliver email. You rarely need to touch them yourself, but when you change hosting or email provider someone has to update them, and a mistake can take your site or email offline for a while.

Changing your domain name later

If you rebrand or outgrow your first choice, you can move to a new domain, but do it carefully. Google advises using permanent server-side redirects (301 or 308) from each old page to its closest new equivalent, keeping them in place for as long as possible and generally at least a year, and submitting a Change of Address in Search Console. Google also notes that rankings may fluctuate during a move, so plan it for a quiet period. Details are in Google's guide to site moves with URL changes.

A simple checklist before you buy

1. Pick a short, memorable name and check nobody else is using something similar.

2. Decide who the registrant will be: your business.

3. Register through a reputable registrar and keep the login safe.

4. Turn on auto-renew and set a calendar reminder.

5. Tell your designer the registrar details so they can connect the site, or ask us to help via our website requirements page.

Frequently asked questions

What is the difference between a domain name and hosting?

The domain name is your website's address. Hosting is the service that stores your website's files and serves them to visitors. You need both for a website to work.

How much does a domain name cost?

Prices vary by registrar and by the ending you choose, so compare a few before buying and look at the renewal price as well as the first-year price. We do not quote domain prices here because they are set by the registrar you use.

Should I let my web designer register my domain?

You can ask them to do the set-up, but make sure you are named as the registrant and have your own login. That way the domain stays yours if you change supplier.

What happens if my domain expires?

Your website and email linked to it can stop working. Grace periods and renewal rules differ between registrars, so check yours, and turn on auto-renew to avoid the risk.

Do I need a .co.uk or is .com fine?

Either can work. A UK ending signals a UK business, while .com is widely recognised. Choose the one that fits your customers and is available in your business name. If you have legal or trademark concerns about a name, check with a solicitor.
