To choose a domain name, write a short list of candidates and run each one through six tests: keep it short, make it easy to say and spell, prefer .com, skip hyphens and numbers, confirm it is not someone's trademark, and check the exact match is available — then register the winner the same day. That sentence is the whole method. The rest of this guide explains each test, gives you a comparison table and a step-by-step checklist, and points you at the free generators and checkers on this site so you can move from a blank page to a registered name in an afternoon.
Your domain is the one piece of branding you will repeat in every email signature, ad, invoice, podcast mention and business card for years. A name that is hard to spell quietly taxes you forever: support agents spell it letter by letter, customers mistype it into the address bar and land on a competitor or a 404, and word-of-mouth referrals leak because nobody can remember it. A clean, short, sayable name does the opposite. It compounds. So the half-day you spend choosing well is one of the highest-return decisions in the whole launch.
Naming also locks in switching costs. Rebranding later means new logos, new printed material, 301 redirects, lost link equity and confused customers. It is far cheaper to get the name right once than to fix it after you have built an audience. Treat the choice as a one-way door and give it the attention that deserves.
Shorter names are easier to remember, type, and fit on a card. Aim for 14 characters or fewer in the part before the dot (the second-level domain). The average strong .com sits around 12 to 15 characters. Two-word combinations — a verb plus a noun, or an adjective plus a noun — that stay under that line are the sweet spot. If you are unsure, paste candidates into our domain name length checker, which grades each one against the 14-character best-practice rule and flags anything that runs long.
A brandable name is a coined or evocative word that becomes meaningful because you give it meaning. A keyword name describes what you do in plain words. Brandable names are distinctive, easier to trademark, and do not box you in when you expand. Keyword names give instant clarity but age badly: a shop named bestcheapwidgets.com looks dated the day you add a second product line, and the supposed SEO boost of exact-match keyword domains has been negligible for years. Our deep dive on exact-match vs brandable domains walks through the trade-off in detail, and what makes a good brand name covers the linguistics of memorable coinages.
Despite a thousand-plus extensions existing, .com remains the default people assume and the one they type without thinking. If you launch on a different extension, type-in traffic and verbal referrals can leak to whoever owns the .com. That said, .co, .io and .ai are well accepted in startup and tech circles, and .org carries trust for nonprofits. The table further down compares the main options.

Hyphens vanish in speech — say "my site dot com" aloud and nobody knows whether to type a dash. They also look cheaper and invite typos. Numbers are worse: "get4less" could be "get four less" or "get-4-less," and a listener has no way to know. Use a number or hyphen only when it is genuinely core to the brand, such as a well-known "24/7" play. As a rule, if you have to explain the spelling out loud, the name is leaking value.
Read every candidate aloud, then have someone who has never seen it type it from hearing it once. If they hesitate or get it wrong, the name fails. Watch for homophones (site/sight, to/two/too), doubled letters where two words join (swiftthreads has three t's in a row), and foreign-language clashes if you sell internationally. The goal is a name that someone can hear at a conference and type correctly from memory the next morning.
A domain being available to register does not mean it is legally free to use. If your name collides with an existing trademark in your industry, you can be forced to rebrand or lose the domain in a dispute. Before you commit, search the U.S. Patent and Trademark Office's free Trademark Electronic Search System (TESS) at uspto.gov for your name and close variants, and do a plain web search for companies already using it. For a serious commercial brand, have a trademark attorney clear it. This step costs minutes and saves rebrands.
Pick a name that survives growth: avoid baking a single city, year, or product into it unless that is permanent. Then check the exact match is actually available — research it, sleep on it, and someone may register it tomorrow. Run your finalist through our domain name search and, once it's clear, register it the same day.
| Choice | Best for | Strengths | Watch out for |
|---|---|---|---|
| Brandable .com | Most startups and products | Distinctive, trademarkable, ages well | Short ones are scarce/expensive |
| Keyword .com | Local/single-service businesses | Instant clarity of what you do | Boxes you in; little SEO edge |
| .co | Startups when .com is taken | Close to .com, widely accepted | People still type .com by habit |
| .io / .ai | Tech, dev tools, AI products | Strong signal to a tech audience | Pricier renewals; niche outside tech |
| .org | Nonprofits, communities, open source | High trust for mission-driven work | Looks off for a for-profit shop |
| ccTLD (.de, .co.uk) | Single-country businesses | Local trust and relevance | Signals "local only" to others |
Once a name passes every test, register it immediately. Domain availability is volatile, and a name you researched on Monday can be gone by Wednesday. Buy the exact .com first. Then decide whether to defensively register a close variant (a common misspelling, or the .co/.net) and the matching usernames on the platforms you'll use, so a squatter or competitor can't ride your brand. Turn on auto-renew so you never lose the name to an expired card, and enable WHOIS privacy to keep your contact details off public lookups. You do not need to buy fifty variations — that is a waste — but owning the exact match and one or two obvious defensives is cheap insurance.
Start with a short list of name candidates, then test each one against six criteria: keep it short (ideally 14 characters or fewer before the dot), make it easy to say and spell, prefer .com, avoid hyphens and numbers, confirm it is not a registered trademark, and check the exact .com is available. Pick the candidate that passes the most criteria, then register it before someone else does.
For most businesses .com is still the safest default because people assume it and type it automatically. Alternatives like .co, .io and .ai work well for startups and tech products where the audience is comfortable with them, and .org suits nonprofits. If you pick an alternative, try to also own the .com of your name later to avoid traffic leaking to a competitor.
A brandable name (a coined or evocative word like a made-up two-syllable term) is usually the stronger long-term choice because it is distinctive, trademarkable and not tied to one product. A keyword domain (descriptive words plus a category) can help users instantly understand what you do, but it ages badly if you expand and offers little SEO advantage today. Most modern brands lean brandable.
Yes, in almost all cases. Hyphens get dropped in word-of-mouth because people forget whether the name is one word or hyphenated, and numbers create spoken ambiguity such as 4 versus four. Both increase typos and make the name harder to dictate over the phone or on a podcast. Use them only when the number or hyphen is genuinely central to the brand identity.
Search the USPTO Trademark Electronic Search System (TESS) at uspto.gov for your name and close variations, and run a plain web search for existing companies using it. A domain being available to register does not mean it is legally free to use; using a name that infringes an existing trademark in your industry can force a rebrand or a UDRP dispute. For commercial brands, confirm with a trademark attorney before you commit.
Register it immediately at a reputable registrar. Domain availability changes minute to minute, and a name you researched today can be taken tomorrow. Buy the exact match first, turn on auto-renew and WHOIS privacy, and consider grabbing one or two close variations and the matching social handles so a competitor or squatter cannot ride on your brand.
