Most naming advice stops at "make it memorable," which is useless. What follows is the actual working process: the criteria that matter, the ones that do not, the naming patterns that still leave a free .com, how the rules change by type of business, the legal check nobody does until it is too late, and how to decide when the perfect name is taken.
What makes a good business domain name?
A good domain name survives being spoken out loud. If you can say it once to a stranger in a noisy room and they can type it correctly without asking you to repeat it, you have a good name. Everything else (length, cleverness, keywords) is secondary to that one test. Short and spellable beats descriptive and clever almost every time.
| Criterion | What good looks like | Why it matters |
|---|---|---|
| Length | Ideally under 15 characters, two words or fewer | Shorter names are typed correctly more often and fit in a logo |
| Spellable when spoken | No ambiguous spellings, no "is that with a K or a C?" | Every ambiguity is a lost visitor and a support email |
| Pronounceable | Reads the same way in every head that sees it | People will not say a name out loud if they are scared of saying it wrong |
| No hyphens or numbers | Letters only | Hyphens get dropped in speech, numbers create a digit-or-word problem |
| Extension | .com where possible, a credible alternative otherwise | .com is still what people type by default |
| Trademark clear | No conflicting USPTO mark in your category | A conflict can cost you the name and the brand equity built on it |
| Handle available | Matching or near-matching social handles free | Fragmented handles across platforms confuse customers permanently |
| Not accidentally something else | Read the joined-up string carefully | Word boundaries disappear in a URL and the results can be unfortunate |
Naming patterns that still leave a free .com
Lists of ready made names fail for one reason: by the time a list is published, the good .com names on it are gone. Patterns age better, because you fill them with your own words. These six produce the most candidates that are still unregistered.
- Fused compounds. Two ordinary words from your trade pushed together until the seam disappears, such as a single word built from a material and a verb. Easy to say, easy to spell, and the pool is close to unlimited.
- Clipped roots. A longer word cut short so the clip carries the character. Short names are typed correctly more often and fit on a sign, a truck door or an app icon.
- Craft plus place. A trade word joined to the town, river or region you serve. Strong for local businesses, weak if you plan to move or expand, because the place in the name starts lying about you.
- The borrowed noun. A concrete word from outside your industry applied to it, such as harbor, ledger, anvil or meridian. Distinctive enough for a trademark without asking anyone to learn an invented word.
- Invented, sound first. Two or three syllables that mean nothing until you make them mean something. The hardest to sell to a co founder, the easiest to protect, and the most likely to have a free .com.
- Brand plus a modifier. When the bare word is taken, a short verb or noun in front of or after it, such as get, try, use, hq or app. Fine for software and online stores, weaker for anything spoken on the phone.
Choosing a domain name by type of business
The criteria above hold everywhere, but each kind of business has one surface the name has to survive, and that surface decides which candidates win.
Local services and trades
Your name is said over the phone and read off a van. Run the radio test twice, keep it under about fifteen characters, and accept craft plus place if your customers are within one city. Check the state business register as well as the domain, because two plumbers with near identical names in one county confuse customers and reviews.
Restaurants, bars, cafes and food trucks
The name is shouted across a room, typed into a map app and printed on a sign or a wrap before the website exists. Puns work when the cuisine is obvious from the pun and fail when they need explaining. Register the domain before the signage, the menu or the wrap goes to print, because changing a physical name later costs far more than a registration.
Trucking and logistics
The legal name or trade name has to appear on the side of the vehicle together with the USDOT number, so the name needs to read at a distance and stand apart in a carrier search where brokers compare dozens of similar companies. Generic stacks of words like express, freight and transport blur together. A distinctive first word followed by one trade word is easier for a broker to remember and easier to find as a .com.
LLCs and professional firms
An LLC name has to clear three separate registers: the domain registry, your Secretary of State entity register (where the name must be distinguishable and usually carry a designator such as LLC), and the federal trademark record. Check them in that order, because the domain check is the fastest and removes the most candidates. The domain does not need the LLC designator in it.
Online stores, apps and websites
Your name is clicked and typed rather than spoken, so a modifier or a newer extension costs less here than anywhere else. A store that sells one product line can use a descriptive word in the name, but leave room to grow beyond that line. If you plan to sell on a platform, register the domain in your own account rather than the platform's, so the address stays yours if you move.
What is the radio test?
The radio test asks whether someone could hear your domain name on the radio, remember it for two minutes, and type it correctly. Say the name out loud to three people who have never seen it written. If any of them ask "how do you spell that?" the name has failed. It is the single cheapest naming filter and almost nobody runs it.
Names fail the radio test in predictable ways. Deliberate misspellings ("Kwik", "Lyft") work only if you have marketing money to teach people the spelling. Homophone traps ("SiteWrite" vs "SightRight") force a coin flip. Doubled letters at a word boundary ("MetalLathe") make people hesitate. Any of these can be overcome with budget, and none of them should be a problem you volunteer for.
Is .com still better than other extensions?
Yes, for most US businesses. The .com is still the default people type, the default they assume, and the one they will land on if they misremember your extension. If you build on a .io and someone owns the .com, a meaningful share of your traffic will end up at their door. That is the real cost, and it does not go away.
That said, alternative extensions are genuinely fine in specific cases. If your audience lives entirely inside a niche where the extension is native and understood, the penalty is small. Developer tools on .dev, AI products on .ai, and design studios on .studio all read as intentional rather than as a consolation prize. Country codes make sense when you serve one country. What does not work is picking an odd extension purely because it was cheap and available, and hoping customers will remember. If you are weighing one against another, the list of available domain extensions shows what each one renews at and which carry eligibility rules.
If you choose a non-.com, choose it because it says something. If you chose it because the .com was taken, you did not choose it, you settled, and your customers will feel the difference every time they type it.
Should I use keywords in my domain name?
No, not as an SEO strategy. Exact-match keyword domains (bestdentistchicago.com) lost their ranking advantage many years ago, and search engines now treat them as neutral at best. A keyword domain will not rank you. It can actively hurt you by making a real brand impossible to build and by reading as spam to the exact customers you want.
What keywords still do is set expectations. A name that hints at the category can lower the cost of explaining what you do, which is useful for a local service business where clarity beats brand. But there is a difference between a name that suggests a category and a name that is a search query with a .com on the end. The first is fine. The second boxes you in the moment you expand past that one service in that one city.
Brandable vs descriptive
Brandable names (invented or repurposed words with no literal meaning) are harder to launch and much better to own. They are ownable, trademarkable, and they scale when your business changes. Descriptive names get you understood on day one and then become a cage. Most companies that matter picked brandable, spent the early money teaching people what the word meant, and never had to rename when the product shifted.
If you are stuck for candidates, change the input rather than staring harder at your own five favorite words. Write down the words your customers use for the problem, the verbs of your trade, the place you serve and a few concrete nouns from outside your industry, then combine them using the patterns below. Expect forty ideas, of which two are worth putting on a shortlist.
How do I check a domain name for trademark problems?
Search the USPTO trademark database before you buy, and search it for your category specifically, not just for an exact string match. Trademark rights are scoped to classes of goods and services, so "Apex" can legally exist as a plumbing company and a software company at the same time. A conflict only exists if someone holds the mark in a space close to yours.
Run the free searches yourself first: USPTO's search tool, a plain Google search of the name plus your industry, and a check of state business registries. If anything close comes back, pay a trademark attorney for an hour of their time before you spend anything on the domain. Registering a domain gives you zero trademark rights. Someone with a valid mark can take the name from you through a UDRP proceeding, and the money you spent on the domain, the logo, and the packaging goes with it.
Should I register a new domain or buy one on the aftermarket?
Register a fresh name if you can find one that passes the criteria above, because it costs a low yearly fee and you own it in minutes. Buy on the aftermarket when the name you actually need is already taken and the difference in quality is worth real money. Short, clean, one-word .com names are essentially all registered already, so if that is your requirement, the aftermarket is your only route. If the shortlisted name turns out to be owned by somebody, the walkthrough of how to buy a domain name that is already taken covers the approach that actually works on an unresponsive owner.
The honest math: a premium name can save you years of explaining who you are, and it can also drain a runway you needed for the product. If you are pre-revenue, a good coined .com you can register today at standard cost is usually the smarter allocation. If you are funded, established, or in a category where credibility is the whole sale, an aftermarket name earns its price. When you do go that route, the purchase runs nothing like a registration, and an estimate of what the name is worth gives you a reference point of your own before you name a number.
A practical process for shortlisting and deciding
Naming stalls because people try to find the perfect name in one sitting. Split it into stages and it becomes tractable.
- Generate wide, judge later. Get to 40 or 50 candidates before you eliminate anything. Mix coined words, real words used sideways, and two-word compounds.
- Kill on hard criteria. Cut anything unspellable, unpronounceable, hyphenated, or over about 15 characters. This usually removes half.
- Check availability on the survivors. Run each one through a domain name search rather than trusting an old list or a screenshot. Unregistered means yours for the ordinary fee. Registered means the price is somebody else's to set, and some names you assumed were dead are quietly purchasable.
- Run the radio test on the top eight. Say them out loud to real people. Watch for hesitation, not opinions.
- Trademark screen the top three. USPTO search plus a category search. Anything ambiguous goes to a lawyer or gets dropped.
- Check handles, then commit. Buy the domain, secure the handles the same day, and stop deliberating. The name matters less than what you build on it. If you are still deciding where to buy it, compare on the renewal price rather than the first-year promotion, which is what the best domain registrar comparison is built around.
Pick the shortest name that survives being said out loud, that no one else has a legal claim to, and that you will not be embarrassed to say in a meeting five years from now. Get the .com if it exists at a price you can defend. Then go build.
