Buying a domain name is an important first step when building a website, but it can feel confusing if you’re unsure what to look for. This guide explains how domains work, what to consider before purchasing, and how to choose the right extension for your project.
For example, if you choose a name like 123blog, you’ll also need to decide on a domain extension. The most widely used extension is .com.
Domain extensions can also influence how visitors perceive your website. Some indicate a global presence, while others target specific countries or industries.
For example, .com is commonly used for commercial websites, while .co.uk is typically used for businesses targeting users in the United Kingdom.

How long can you register a domain for?
Domain names are typically registered for a minimum of one year, with most providers offering up to a 10-year registration period.
If your domain is not renewed before it expires, it becomes available for others to register.
Many registrars offer automatic renewal options to prevent accidental expiration and loss of ownership.
Do you own a domain name?
A domain name cannot be owned permanently. Instead, it is leased for a set period of time based on your registration term.
As long as you continue renewing it, you retain control over the domain.
Do you need a domain to build a website?
Some providers offer temporary subdomains, which allow you to build and test a website without purchasing a domain.
However, using a custom domain is strongly recommended for professionalism, branding, and search engine visibility.
How many characters can a domain contain?
Domain names can range from 2 to 67 characters depending on the extension.
Choosing a short, simple, and memorable name is usually best for branding and repeat visitors.
Your domain is your brand identity, so it’s important to check availability and avoid overly complex wording.
Choosing the right domain the first time
It is important to double-check spelling before registering a domain, as most registrations are non-refundable.
Even if a domain is registered by mistake, you will still own it for the full registration period until it expires.
Types of domain extensions
There are many domain extensions available, each with different purposes and geographic targeting.
| Extension | Target | Description |
|---|---|---|
| .COM | Global | Most popular commercial extension worldwide |
| .BIZ | Global | Business-focused extension |
| .CO | Global | Often used for companies and startups |
| .CO.UK | UK | Targets businesses in the United Kingdom |

| .TV | Media | Video and entertainment sites |
Domain pricing
Domain prices vary depending on the extension and popularity, typically ranging from around £10 to £80 per year.
Premium or short domains can sell for significantly higher amounts due to demand and branding value.
Some of the most expensive domains ever sold include high-value keywords and brandable names.
- CarInsurance.com — $49.7 million
- Insurance.com — $35.6 million
- VacationRentals.com — $35 million
- PrivateJet.com — $30.18 million
- Voice.com — $30 million
- Internet.com — $18 million
- 360.com — $17 million
- Insure.com — $16 million
Expired domains
Expired domains are previously registered names that were not renewed by their owners. Some may still hold SEO value or backlinks, making them attractive for resale or development.
Can you build a website with just a domain?
A domain alone is not enough to build a website. You also need web hosting to store your website files and make them accessible online.
A domain acts as the address, while hosting is the space where your website lives.
What characters are allowed in a domain?
Domains can include letters, numbers, and hyphens.
Special characters such as symbols or punctuation marks are not permitted.
How to choose a domain name
When choosing a domain, focus on clarity, simplicity, and relevance to your brand or niche.
Once you’ve decided on a name, you can register it through a domain provider after checking availability.
Should domain and hosting be bought together?
It is not necessary to purchase domain and hosting from the same provider, although some companies offer bundled deals.
Comparing providers can often help you find better pricing or features.
Some hosting packages may also include a free domain as part of the plan.
Summary
Choosing the right domain name is an important part of building a successful website. Always research your options, check availability carefully, and select an extension that matches your target audience.
Once registered, your domain becomes a long-term part of your brand identity, so it’s worth taking time to choose wisely.
