Choose a domain name you can say once over the phone and have the other person spell it correctly on the first try. Keep it short, skip hyphens and digits, take the .com if it is free, and run a trademark check before you pay. Everything after that is taste.
Most advice on how to choose a domain name treats it as a branding exercise. It is closer to a spelling test. The name will be read aloud on phone calls, typed from memory into a browser bar by somebody who saw it on a van three days ago, and printed on an invoice next to an email address, and every one of those situations punishes a name that needs explaining.
How to Choose a Domain Name That Survives the Phone Test
Say the candidate to somebody who has never seen it written down, then ask them to type it. Do not spell it for them. Do not repeat it. Whatever they type is what the world will type, and if two out of three people get it wrong you have learned something for free that would otherwise have cost you a year of misdirected traffic.
The failures are always the same handful. Possessives, because nobody hears the apostrophe and nobody knows whether to include the s. Plurals, for the same reason. Words with a legitimate second spelling, like grey and gray or theatre and theater. And any name where two words collide into a third word that reads badly, which is worth checking deliberately because you will not see it yourself after the fourth reading.
Short is useful, but shortness is not the goal. A fourteen-character name made of two ordinary words beats an eight-character name assembled from dropped vowels. The reader is not counting letters. They are trying to reproduce a sound.
The Characters That Cost You Years
Hyphens are the one I argue about most, and my position has not moved: do not use one. A hyphenated domain forces you to say "dash" every single time you give out the address, for as long as the business exists, and the version without the hyphen almost always belongs to somebody else who will collect the traffic you paid to advertise.
Digits fail for a related reason. A number in a spoken name is genuinely ambiguous, because "4" and "four" are the same sound, so you have bought yourself two domains worth of confusion and registered one of them.
Doubled letters at a word boundary are the quiet one. Take a name like "webbdesign" or "glasssmith", where one word ends with the letter the next word begins with. People drop the double every time.
Three more things worth testing before you commit:
- Read it in lowercase with no spaces, which is how it will actually appear. Some names that look fine in title case turn into something else entirely.
- Check that it does not read as a different word in another language your customers speak.
- Say it in a noisy room. Names that rely on the difference between an M and an N do not survive a phone call from a job site.
Picking an Extension
The .com is still the default, and the reason is behavioral rather than technical: people type it without thinking, so a name on any other extension leaks some fraction of its direct traffic to whoever owns the .com. The habit is decades old. That cost is small when the .com is parked and unused, and large when the .com belongs to a working business in a similar field, which is the case worth checking before you settle.
Country extensions earn their place when the business is genuinely local and the audience expects one. A plumber in Manchester on a .co.uk reads as a plumber in Manchester. Some registries also restrict who may register, requiring a local presence or a registered company, and that restriction works in your favor because it keeps out the speculators. It also works against you the day you incorporate somewhere else, so check the eligibility rules before you build a brand on one. The TLD information page lists which extensions are available and what each one requires.
Niche extensions are better than their reputation, provided the word before the dot carries the meaning. The .dev and .app extensions have a property most people do not know about: both are on the browser HSTS preload list as entire top-level domains, so browsers refuse to load them over plain HTTP at all. You cannot misconfigure your way into serving an insecure version. For a developer tool or a mobile product, that is a small free guarantee of correctness.
What I would avoid is an extension chosen because the good name was gone in .com and you wanted to keep the word. That is how businesses end up on an extension nobody has heard of, spelling it out on every call.
Before You Pay, Check Who Else Is Using the Name
Availability at a registrar tells you nothing about whether you are allowed to use the name. Do these four checks, in this order, and stop at the first one that comes back ugly.
- Search the exact string in quotes. You are looking for an existing company or product already using it, particularly one in your own industry.
- Search the trademark registers that cover the countries you sell in. In the United States that is the USPTO trademark search; most other jurisdictions publish an equivalent. Look for identical marks and for confusingly similar ones in your class of goods.
- Check the social handles and the app stores. A name already taken everywhere else is a name you will spend years qualifying with underscores.
- Search the term plus your industry word. Sometimes the collision is not a registered mark at all, just an established use that will bury you in search results forever.
None of this is legal advice, and a real trademark question belongs with a lawyer rather than a hosting blog. But the practical exposure is worth understanding: a trademark holder can file a complaint under ICANN's dispute resolution policy and have a domain transferred away from you, and the fact that you registered it first is not by itself a defense.
Which Defensive Registrations Are Worth Paying For
Almost none of them. The standard advice is to buy your name across a spread of extensions and misspellings, which mostly sells domains rather than protecting brands, and every one of those registrations renews every year for as long as you keep paying attention to it.
Three are worth the money. The .com, if you built on something else and the .com is available, because that is the one people type by default. The singular or plural counterpart, if your name is one of those and the other form is the natural thing to say. And a genuine misspelling, only when testing shows most people actually make it.
Everything else is a subscription to a name nobody would have taken. Point the defensive ones at your real site with a redirect and forget them; do not build anything on them, and do not let them collect email.
WHOIS privacy is the one add-on I would buy every time. Registration details are published by default, and the alternative to privacy is your home address in a public database that scrapers read continuously. BestPaidHosting prices WHOIS protection at $6.95, and comparable protection is available at most registrars.
The Name Becomes Your Email Address
Everything gets worse at the second syllable when a domain is spoken as an email address. "hello at" plus your name, over a bad connection, to somebody writing it on a form. Length and hyphens both cost more here than they do in a browser, because there is no autocomplete and no search box waiting to correct the mistake.
A name you own outright also gives you an address that is not tied to a mailbox provider, which matters more than it sounds. Staff change and providers get abandoned, and moving a mailbox to a different provider is a DNS change you make yourself when the domain is yours, from something like Hepsia's domain manager, rather than a negotiation with a company that owns your address. This is one reason the ordering advice in the guide on getting a small business online puts the domain before almost everything else.
There is a search benefit too, and it is quieter than the SEO industry suggests. Keywords in a domain barely move rankings. What a memorable name does is generate branded searches, and a rising volume of people searching your name specifically is a much better asset than an exact-match domain nobody remembers.
If You Already Regret the Name
Changing is survivable. It is also more work than anybody expects, and the ordering matters.
Register the new name and stand the site up on it first. Then send every URL on the old domain to its exact counterpart on the new one with a permanent redirect. Not everything to the homepage. Page for page, or you lose the accumulated value of every link anyone ever made to you. Keep the old domain registered indefinitely, because the redirects have to keep working long after you stop thinking about them, and because letting it expire hands your old traffic to whoever picks it up.
Email is the part that goes wrong. Update the addresses in every account, payment processor, and password reset before you retire the old mailboxes, and keep receiving on the old domain for at least a year afterward.
The Scorecard
| Test | Pass | Fail |
|---|---|---|
| Somebody types it correctly after hearing it once | Yes | Rethink the name |
| Contains a hyphen or a digit | No | Drop it |
| Extension | .com, or a ccTLD you qualify for and intend to keep | An unfamiliar extension chosen as a consolation |
| Trademark and existing-use search | Clean in your industry and your markets | Stop and pick another name |
| Sounds unambiguous spoken as an email address | Yes | Shorten it |
Run the phone test first. It eliminates most candidates in about a minute, it costs nothing, and it catches the specific failures that no amount of staring at the name written down will ever show you. Then take your two survivors through the trademark checks, and register the winner along with the .com if you ended up somewhere else. Check what is free from the domain search, and point the name at hosting the same day.
