Choose a domain name that is short, easy to say and spell, clearly tied to your brand or topic, and free of hyphens or numbers people might mishear. Favor an extension your audience recognizes, check that the name does not clash with an existing trademark, and say it out loud before you buy.
Say every candidate out loud before you buy it
A good domain survives being spoken. Picture telling it to someone over the phone or hearing it in a podcast ad, then ask whether they could type it without help.
Names fail this test in predictable ways. Words with more than one common spelling, like “night” and “nite,” send visitors elsewhere. Numbers leave people unsure whether to type “4” or “four.” Hyphens rarely get said aloud. Double letters where two words meet, such as “bestteacher,” are easy to mistype.
Also read the name as one unbroken string, the way it appears in a browser. Some perfectly innocent word pairs form an unfortunate word when the spaces are removed.
Picking an extension that suits the site
The extension, or top level domain, is the part after the dot. The choice shapes how people remember and trust the address.
| Extension | Typical use | Things to weigh |
|---|---|---|
| .com | Businesses and general sites | The one most people type by habit, so short names are hard to find |
| .org | Nonprofits, groups and projects | Signals a cause or community more than a store |
| .net | Tech services and networks | Often picked when the .com is taken, which can leak traffic to it |
| Country codes such as .us | Sites aimed at one country | Some carry eligibility rules set by the registry |
| Newer endings such as .shop or .app | Niche or descriptive names | Memorable, but less familiar to some visitors |
If the .com of your exact name belongs to an active business in your field, pick a different name rather than a different extension. Visitors will end up on the other site.
Length and character rules for domain names
The technical limits are generous. Under RFC 1035, the internet standard that defines domain names, each label between the dots can be up to 63 characters, using letters, digits and hyphens. Capital letters don’t count as different, so MyShop.com and myshop.com reach the same place.
Practical limits are much tighter. Shorter names are easier to recall, fit on business cards and leave less room for typos. Two short words that describe what you do, or one distinctive brandable word, tend to age better than a keyword string such as “bestcheapplumberdenver,” which also locks you into one city and one service.
Checking trademarks and social handles first
Owning a domain doesn’t give you rights to a name someone else has trademarked. Before you commit, run your top choices through the USPTO trademark search system and look for similar marks in the same line of business, not only exact matches. For anything with real money behind it, talk to a trademark attorney.
Check the major social platforms at the same time. Having the same handle everywhere makes the brand easier to find, and discovering a clash after launch means renaming everything. If you plan to register a business, your secretary of state’s website usually has a business name lookup as well.
Registering the name and keeping it
- Buy through a registrar accredited by ICANN, the body that coordinates domain names.
- Pick a registration term. ICANN notes it is typically between one and ten years.
- Turn on auto renew and keep a payment method on file that won’t expire before the name does.
- Use a contact email you check, since renewal notices go there.
- Turn on the registrar’s privacy option if you don’t want your details in public records.
ICANN’s renewal and expiration FAQ explains that registrars must send reminders about a month and a week before expiry, and that an expired name can enter a 30 day redemption grace period before anyone else can register it. Recovering it at that stage can cost extra, so auto renew is the safer choice.
Frequently asked questions
Is .com still the best domain extension?
For most businesses aimed at a general US audience, .com remains the extension people type without thinking. That familiarity is its advantage. A clear, available name on another reputable extension can work well, especially for nonprofits, local projects or niche brands, as long as the matching .com is not a competitor.
Should a domain name include keywords?
A word that hints at what you do can help people understand the site, but stuffing in several keywords makes a name long, forgettable and spammy looking. Search engines judge the content far more than the address. A short, brandable name that still makes sense usually serves you better over time.
What happens if my domain name expires?
The website and any email on that domain stop working. Under ICANN rules, registrars send reminders beforehand, and many expired names enter a 30 day redemption grace period during which the original owner can still recover them, often for an added fee. After that, the name can be released for anyone to register.
What is a domain name?
A domain name is the readable address people type to reach a website, usually ending in an extension such as .com or .org. Every server online also has a numeric IP address, and Mozilla's developer documentation explains that domain names exist because those numbers are hard to remember and can change. The name points visitors to the right server.
How do you buy a domain name permanently?
You can't own one outright. Mozilla's developer documentation explains that you pay for the right to use a name for one or more years, and your renewal takes priority over anyone else's. The closest thing to permanent is registering for the longest term offered, up to ten years as ICANN notes, and turning on auto renew.
