Register your domain name

Every website has a specific name to identify it on the web, called a domain name. Like your home address, it consists of different parts. The domain name has to be unique and only lead to one website. That’s why you need to check if the domain name you want is still free and not already taken.

A domain name may start with “www.” but web browsers will recognise it automatically, so it’s not essential. The next part of the domain name, the second-level domain, is what people will recognise and remember. It could be your company’s name, for example. The last part is the top-level domain (TLD), which can be generic (.net, .com, .org) or geographic like .uk or .cymru.

To find out if the domain name you want to register is available, use the IONOS domain checker.

Finding the right domain name is the first step in building a successful website and boosting your online presence. Without a strong domain, you risk getting lost in the crowd.

Decide early on if you want to have a brand domain or a keyword domain. Brand domains make a clear link between your business and your website, whereas keyword domains may get better search engine results.

Classic domain extensions like .com work for both options. Country specific extensions (e.g. .co.uk) emphasise local relevance, and new top-level domains such as .video, .business etc. can also be effective.

It's worth registering more than one domain extension, especially the classic extensions such as .com, as many users will remember them better than the nTLDs. If you own the .com version but prefer the nTLD, you can always set up domain forwarding. This also prevents someone else from using your domain name.

It's easy to register a domain name. Here's our step-by-step guide.

1. Choose the domain name you want for your website. You can register more than one.
2. Check whether your domain name is available using our domain checker tool. This will tell you if the domain contains invalid characters, or if it's already claimed.
3. If your preferred domain name is taken, you'll be given alternatives.
4. Add your chosen domain/s to your basket. There may be several different package options to choose from depending on your needs.
5. Check your order for details such as the domain's expiration date, and how many domains you're registering.
6. Create your customer account if you don't already have one.
7. Select your payment method and purchase your domain/s.

If you're already an IONOS customer, you can add new domains by logging in to your account and clicking "add new domain" in the domains drop-down menu.

A domain extension is also known as a top-level domain (TLD). It's the last part of a domain name – in the domain name ionos.com, .com is the domain extension. In an already crowded marketplace, it can be a challenge to choose a memorable and unique domain name, and this includes picking the right domain extension.

There are different kinds of domain extension:

ccTLDs are top-level domains that represent a nation – the 'cc' stands for country code. Some of these domain extensions can require a presence in the relevant country. A .co.uk or .uk domain are examples of ccTLDs. Some of the country code extensions are classified as generic ccTLDs by Google – gccTLDs. This is because the domain is not always used to represent a country. For instance .cc and .io are generic country code top-level domains. The .cc extension is officially the country code extension for the Cocos (Keeling) Islands near Australia, but is also used as 'commercial company', while .IO is the ccTLD for the British Indian Ocean Territory, but is also used to represent 'input/output'.

gTLD is short for generic top-level domain. The classic domains .com, .org, .net are generic domain extensions.

nTLDs are new top-level domains. Each year, up to 1,000 nTLDs are released. They include extensions such as .london, .tech and .cloud.

Certain domain extensions have eligibility requirements, for example the extension .gov is restricted to use by government entities. IONOS does not offer these domain extensions.

Subdomains are useful for organising your website into different categories. Possible categories include:

Geographical areas or language groups

For example, if your website is in English and Spanish, a subdomain may be used to indicate that this section of your website will be in Spanish, and not English – so instead of just ionos.co.uk, es.ionos.co.uk would be used.

Product-oriented sections

If your website offers a variety of different services or products, you can create a subdomain for each one, for example blog.ionos.co.uk.

Gated content

Having a separate subdomain for logins or account pages on your website is a useful way of organising your site.

By using a subdomain, you'll be able to track the success of your website more accurately, as you'll see how different sections are performing.
