Quick answer: To choose a domain name, aim for something short, easy to spell after hearing it once, and close to your business name. Prefer .com if it is available at a sensible price, or your country extension if you serve one country. Avoid hyphens, numbers and awkward spellings. Check trademarks and social handles before buying, register it in your own business’s name with a reputable registrar, and turn on auto-renew so it never lapses.
Why the decision matters
A domain name ends up everywhere: business cards, invoices, vehicle signage, email addresses and every link anyone shares. Changing it later is possible, but it means redirects, new email addresses, updated listings and a period of search ranking uncertainty. Our guide to SEO migrations explains why moving domains takes careful planning.
So it is worth spending an afternoon getting it right rather than grabbing the first available option.
Qualities of a good business domain
Easy to say and spell
Imagine telling someone your domain over the phone or on the radio. If you have to spell it out, explain a hyphen or clarify whether a number is written as a digit or a word, it will cost you visits and emails. “Bright Path Plumbing” works well as brightpathplumbing.com. “Brite Path 4 Plumbing” does not.
As short as practical
Shorter domains are easier to remember and type, especially on phones. That does not mean you need a three-letter domain. Two or three real words that describe your business are fine. Aim to stay under about 15 characters where you can, but clarity beats brevity.
Close to your brand
The best domain is usually your business name. Customers who hear your name should be able to guess your web address. If your exact name is taken, small, natural additions work: your city, your trade or a word like “get” or “hello,” as in getbrightpath.com or brightpathplumbing.co.uk.
No hyphens or numbers
Hyphens are easy to forget when typing, and people who leave them out may end up at a competitor’s site. Numbers create the “digit or word” problem. Both are acceptable only if they are genuinely part of your brand.
Not easily misread
Check how the words run together. Some combinations accidentally spell something unfortunate when written without spaces. Read the domain in lowercase, all as one string, and ask a few people to read it back.
Choosing an extension
.com is still the default
For most businesses, .com is what people assume. If someone hears your name and guesses the web address, they will usually try .com first. If the .com is available or affordable, it is usually the right choice.
Country extensions
If you serve one country, a country code extension like .co.uk, .ca, .com.au or .in can be a strong choice. It signals local relevance to customers, and Google uses country code extensions as a signal for geographic targeting. If you plan to sell internationally, a .com or generic extension gives more flexibility.
Newer generic extensions
Since 2014 hundreds of new extensions have become available: .agency, .studio, .shop, .law, .dental, .app, .dev and many more. They can produce short, memorable names when the .com is taken. Google has said these extensions are treated like any other generic extension for ranking, so they do not help or hurt SEO on their own.
The trade-offs are that some people still find them unfamiliar, some email systems and forms have been slow to recognize them, and renewal prices can be higher than the first-year price. Check renewal costs before buying.
Note that .app and .dev require HTTPS on every site, because those extensions are on browsers’ HSTS preload list. That is good practice anyway, but your hosting must support it.
Should you include keywords?
Years ago, exact-match domains like best-cheap-plumber-london.com had an advantage in search. Google reduced that effect with an update in 2012, and keyword-stuffed domains now often look spammy to people.
A light descriptive word is still useful when it clarifies what you do, such as including “plumbing” or “law” alongside your name. But choose a brand you can grow with. If you name your company dublinwebdesign.ie and later expand to other cities or services, the domain will feel limiting.
Checks before you buy
Trademarks
Search your country’s trademark database and the business registry for the name. Owning a domain does not protect you if it infringes someone else’s trademark, and a dispute could force you to give it up.
Social media handles
Check whether matching usernames are available on the platforms you use. Consistency helps people find you, though it does not have to be perfect.
Domain history
If the domain was previously registered, look it up in the Wayback Machine to see what was there. A domain used for spam may carry problems. Our article on domain authority touches on what third-party metrics can and cannot tell you about a domain’s past.
Similar domains
If a well-known business uses a very similar domain, you may lose traffic and emails to them, or they to you. Avoid names that are one letter away from an established brand.
Buying premium or taken domains
If your ideal domain is registered but not in use, it may be for sale. Some are listed on domain marketplaces; others need you to contact the owner. Prices range widely. Decide your maximum in advance, use an escrow service for anything significant, and make sure the transfer completes before you rebrand.
Often a good alternative is cheaper than chasing the perfect name.
Registering it the right way
Use a reputable registrar
Choose a registrar with clear pricing, two-factor authentication, easy DNS management and straightforward transfers. Avoid bundling your domain with a cheap hosting deal that makes it hard to move later.
Register in your business’s name
The registrant on record should be your business, with an email address you control. Many businesses discover too late that a former web designer or employee registered the domain under their own account. Our guide to website ownership explains what you should hold the keys to.
Turn on auto-renew and registrar lock
Expired domains can be snapped up within days, taking your website and email with them. Turn on auto-renew, keep the payment card current and enable registrar lock to prevent unauthorized transfers. We cover more protections in our article on domain security.
Privacy protection
Since GDPR came into force in 2018, many registrars redact personal details from public WHOIS records automatically. Where they do not, privacy protection keeps your personal address out of public records and reduces spam.
Consider defensive registrations
If budget allows, register common misspellings and the main alternative extensions, and redirect them to your main domain. This is optional, but it stops others from using them.
Setting it up
Once registered:
- Point the domain to your hosting with the right DNS records.
- Set up professional email on the domain, not a free webmail address.
- Install an SSL certificate so the site loads over HTTPS.
- Redirect the www and non-www versions to one preferred version.
- Add the site to Google Search Console.

FAQ
Does the domain name affect SEO?
Less than many people think. Content, links and site quality matter far more. A clear, brandable domain helps indirectly because people remember it and trust it.
Should I buy several extensions?
Buying the .com and your country extension is sensible for many businesses. Redirect extras to your main site rather than running separate sites.
Can I change my domain later?
Yes, with proper 301 redirects and planning. Expect a temporary dip in search traffic and plenty of admin work updating listings and email addresses.
How much should a domain cost?
A standard registration usually costs a modest annual fee. Premium names and some newer extensions cost much more, so compare renewal prices, not just first-year deals.
Next step
Write down five candidate names, test them aloud with a few people, run the checks above and register your favorite with auto-renew on.
