What Is a Domain Name?
A domain name is the address people type into a browser to visit your website, such as:
- example.co.uk
- example.uk
- example.com
When you register a domain, you’re effectively renting the right to use that web address for a specific period, usually between one to ten years.
Understanding Domain Suffixes (aka Extensions)
No doubt you’ll have seen a wide range of choices in terms of the suffix (the end bit of your domain name). From the traditional .com to the more recent .ai or .app, there’s plenty of choice. However, in the interests of keeping things simple, we’ll look at some of the most common.
.co.uk
The .co.uk extension has been the traditional choice for UK businesses for many years. It specifies a business is operated in the UK and is a “familiar choice” for many web users, giving across trust signals of an established business. It is best used by companies targeting UK customers.
Advantages of a .co.uk domain
- Widely recognised and trusted
- Familiar to UK consumers
- Strong local identity
Example: yourbusiness.co.uk
.uk
The shorter .uk extension was introduced by the UK’s domain registry, Nominet in 2014 as a cleaner and modern alternative to the traditional .co.uk. Many businesses choose to secure both, redirecting one to the other, in order to stop competitors from taking the domain.
Despite being introduced as a clean and modern option, .co.uk still dominates UK registrations by a significant margin – .uk domains still only account for around 14% of all UK domain registrations.
To that end, if you can get the .co.uk then we’d recommend doing so, but if the .uk is the only option, then there’s still strength in securing it.
Advantages of a .uk domain:
- Shorter and easier to remember
- Cleaner branding
- Growing steadily in popularity among UK businesses
Example: yourbusiness.uk
.com
The .com domain extension was originally introduced in 1985 and has become the most recognised domain extension in the world. While it was initially intended for commercial organisations, it is now used by businesses, brands and individuals across virtually every industry.
If you are a UK business but serve (or intend to serve) customers internationally, a .com domain is a good idea, even if you register it initially and redirect it with the view to develop it later on. Many UK businesses choose to register both the .co.uk and .com versions of their domain, redirecting one to the other to protect their brand and prevent competitors from acquiring a similar web address.
Despite the growth of newer domain extensions, .com remains the most widely used and recognised domain extension globally, with over 150 million registrations worldwide. However, many desirable .com domains have already been registered, making it harder to secure your first-choice name.
Advantages of a .com domain:
- Globally recognised and trusted
• Ideal for businesses targeting international customers
• Professional and established reputation
• Easier for overseas visitors to identify and remember
• Often viewed as the default domain extension
Example: yourbusiness.com
Registering a Domain
There are a number of steps to follow in order to find, secure and pay for your desired domain(s).
Step 1: Check Domain Availability
The first thing to do is search for your desired domain name using a domain registrar’s search tool. There are many options; for the purpose of this guide, we have used one of the most popular, GoDaddy.
Check:
- yourbusiness.co.uk
- yourbusiness.uk
- yourbusiness.com
- Common misspellings if brand protection is important
If your first choice is unavailable, consider alternatives rather than adding unnecessary hyphens or numbers – however, do add numbers if these are part of your business name.
Good Examples
- youbusiness.co.uk
- yourbusiness.uk
- yourlocalbusiness.co.uk
Poor Examples
- yourbusiness-2026.co.uk
- yourbusiness1234.uk
- best-business-online.co.uk
Step 2: Research the Domain's History
Just because a domain is available doesn’t mean it has a clean history. A domain with a bad history can sometimes create SEO and reputation issues.
What is a bad domain history?
A bad domain history is when a domain has previously been used for activities that could harm its reputation or search engine performance. This might include being used for spam emails, low-quality SEO tactics, malware, gambling, adult content, or being part of a network of websites created purely to manipulate search rankings.
Before buying a domain, it’s worth checking its history using tools such as the Wayback Machine and backlink checkers such as Ahrefs. A domain with a poor history could make it harder to rank in search engines and may even damage your brand’s credibility if previous content was inappropriate or untrustworthy.
Before purchasing, check:
- Whether it was previously used and what for
- Whether it was associated with spam (In this context, spam generally refers to the use of a domain for unsolicited, deceptive, or low-quality online activity).
- Whether it has a poor search engine reputation. If you type it into Google and few results appear or the content looks suspicious, this could be a red flag.
- Whether it was linked to controversial content including adult content, gambling sites or low quality websites.
Useful tools include:
- Internet Archive (Wayback Machine)
- Search engine results for the domain name
- Backlink analysis tools
Step 3: Check for Trademark Conflicts
A domain being available does not automatically mean you can safely use it without worrying about trademark conflicts. Using domains that potentially infringe on another company’s trademark could lead to legal disputes and potential loss of the domain.
Before buying:
- Search UK trademarks
- Search Companies House records
- Search Google for similar brands
- Check social media platforms
Step 4: Choose a Reputable Registrar
A registrar is the company that registers and manages your domain name. One such example would be GoDaddy, the world’s largest, or 123.reg. You’ll want to use a reputable one, as ideally you want free WHOIS privacy included.
When comparing registrars, look for:
Transparent pricing – Some providers advertise a very low first-year fee but charge significantly more for renewals.
Free WHOIS privacy (where available) – Privacy services help reduce spam and protect personal details where applicable.
Good customer support – If something goes wrong with your website or email, responsive support can be invaluable.
Always check:
- Registration cost
- Renewal cost
- Transfer fees
- Additional charges
Easy domain management is also very important. Nobody needs to take a training course in how to navigate their own domain dashboard.
Look for:
- Simple DNS management
- Domain forwarding
- Email setup options
- Two-factor authentication
Step 5: Register the Domain
Once you’ve chosen your domain:
- Add it to your basket.
- Select the registration period (typically 1–10 years).
- Create an account with the registrar.
- Review all optional extras carefully.
- Complete payment.
After registration, the domain is usually active within minutes.
Common Mistakes to Avoid
CHOOSING A DOMAIN BASED ONLY ON PRICE
The cheapest registration fee can become expensive if renewal costs are high.
USING HYPENS UNNECESSARILY
Many users forget hyphens and may end up on another website.
ADDING NUMBERS TO FOR AVAILABILITY
Adding in random numbers often makes domains harder to remember and communication. Exception: if the number is part of your business name, then this is a different scenario.
FORGETTING RENEWALS
Expired domains can sometimes be purchased by someone else. Enable automatic renewal whenever possible.
NOT REGISTERING RELATED DOMAINS
If your brand is important, consider registering complementary extensions, including .uk, .co.uk, .com
USING COPYRIGHTED OR TRADEMARKED NAMES
Even if available, these domains can create legal problems later.
Quick Checklist
Is it easy to spell? If people hear your name in conversation, can they type it correctly?
Is it easy to remember? Shorter domains are easier to recall.
Does it match your brand? Your domain should support your business name and long-term plans.
Could it be misread? Say the domain out loud and ask others to read it. Certain word combinations can unintentionally create confusing meanings.
Are social media handles available? Ideally, your domain and social usernames should be consistent across platforms.
Are there any trademark concerns? If so, reconsider the domain and perhaps even the business name.
