Your domain name is often the first impression a potential customer has of your business. It appears on business cards, email addresses, search results, and every piece of marketing you produce. Getting it right matters, and getting it wrong is expensive and disruptive to fix. This guide covers what makes a strong business domain, what to avoid, and how to handle common situations like your ideal name already being taken.
Short. Aim for under 15 characters in the domain name (excluding the TLD). Shorter domains are easier to remember, easier to type without errors, and less likely to be misheard when spoken. Every extra character is a potential typo or miscommunication. The ideal is 6–12 characters.
Easy to spell and say. If you have to spell out your domain name every time you say it, it's too complicated. Test it verbally: tell someone your domain name without writing it down and see if they can type it correctly from memory. If they can't, simplify it. Avoid unusual spellings, homophones that could go either way (e.g., "to" vs "two" vs "too"), and abbreviations that aren't universally understood.
No hyphens or numbers. Hyphens in domain names are widely associated with spam and low-quality sites. Search engines don't penalise them, but user perception is negative. Numbers create ambiguity, is it the digit "4" or the word "four"? Avoid both unless your brand name specifically uses them (e.g., 99designs.com works because the number is part of a well-established brand).
.com is still king. For a business domain, .com is the default choice and the one most users expect. If someone is told about a business verbally and then types the domain from memory, they will instinctively try the .com first. If your .com goes to a competitor or a parked page while your business is at .net or .co, you're sending potential visitors somewhere else.
That said, .com scarcity has pushed many businesses to credible alternatives. Country-code TLDs (.co.uk, .ca, .com.au) are perfectly acceptable for businesses operating in those countries. Industry-specific TLDs (.agency, .studio, .law, .shop, .tech) can work well for certain niches, particularly in creative industries where a domain like smith.design reads as intentionally modern rather than a second-choice fallback.
Avoid obscure TLDs (.xyz, .online, .site) for primary business domains. They're cheap and available, but they carry negative associations in users' minds and are disproportionately used for spam and low-quality sites. If you register one, also register the .com equivalent if it's available, or accept that some percentage of traffic will go to the .com instead.
Brand name domains (e.g., apple.com, stripe.com) are made-up words or repurposed words that have no inherent meaning but become synonymous with the company. They're short, memorable, trademark-friendly, and flexible as the business grows. The downside: they require brand-building effort before they carry any recognition.
Descriptive domains (e.g., cheapflights.com, bookkeepingfordentists.com) tell visitors immediately what the business does and can rank well in search results for those keywords. The downsides: they're often taken, can become limiting as the business evolves, and may be harder to trademark (generic terms can't usually be trademarked). A domain like manchesterlawyers.co.uk works well for local SEO but constrains you if you expand nationally.
The practical answer for most small businesses: aim for a domain that is either your business name (if it's short and available), a shortened version of your business name, or a coined word that's easy to say and spell. Avoid both the overlong descriptive approach and completely random strings of letters.
Most short, desirable .com domains are registered. Check the WHOIS record to see who owns it and whether the site is actively used or just parked. If it's parked or unbuilt, you can attempt to buy it, either directly through a WHOIS contact email, or through a domain broker service like Sedo or Dan.com. Expect to pay $500–$5,000+ for desirable short .com domains; premium one-word domains can cost hundreds of thousands.
If buying isn't feasible, consider these alternatives: add a geographic modifier (smithplumbing-london.com), add a descriptor (smithplumbingco.com), use the .co.uk or country-specific equivalent, or create a new brand name that has an available .com. The last option, create a brand with an available domain, is often the cleanest solution for new businesses, as it avoids the limitations of a compromised domain from day one.
Before registering, check whether the domain name conflicts with an existing trademark. In the US, search the USPTO trademark database (tmsearch.uspto.gov). In the UK, use the UKIPO trademark search (trademarks.ipo.gov.uk). In the EU, use EUIPO (euipo.europa.eu). If another company holds a trademark on a name similar to yours, registering the domain doesn't protect you, they can file a UDRP (Uniform Domain-Name Dispute-Resolution Policy) complaint and potentially force a transfer.
Also do a basic web search for your intended domain name and business name. If a well-established business with the same or similar name operates in your industry, even without formal trademark registration, using the same name creates confusion and potential legal risk. This is especially important if you're considering a domain that's very close to a larger brand's name, even an unintentional trademark infringement is costly to defend.
Once you've chosen your domain, consider registering common variations to protect your brand. At a minimum, register both the .com and your country's ccTLD (.co.uk, .ca, etc.) if you operate locally. If your domain could be mistyped in a common way, register the misspelling too, redirect it to your main domain.
This defensive registration doesn't need to be expensive or comprehensive. Focus on the most credible alternatives, primarily .com and your local ccTLD. You don't need to register every possible TLD for every possible spelling variation. Just cover the ones most likely to be typed by someone trying to find your site and the ones most likely to cause brand confusion if held by a third party.
