TL;DR

  • Your domain name is your website’s address (like yoursite.com). It’s what people type to find you, what’s on your business cards, and what appears in Google results.
  • The rules: short, memorable, easy to spell over the phone, no hyphens, no numbers, and .com first. Always .com first.
  • Don’t overthink it — your domain doesn’t need to be clever. It needs to be easy for someone to type after hearing it once.
  • You can register a domain for about $12/year. If your first choice is taken, there are practical strategies to find a good alternative.

You’re ready to build a website. The developer asks: “What’s your domain name?” You type your name into a domain registrar. It’s taken. You try your name plus “plumbing.” Taken. Your name plus “austin.” Taken. Fifteen variations later, you’re considering “contoso-plumbing-austin-tx-247.com” and wondering if hyphens are really that bad. (They are.) There’s a better way.

What Is a Domain Name?

A domain name is your website’s address — the text people type into their browser to find you (like contosoplumbing.com). It’s separate from your website itself. Think of it as your street address; your website is the house.

You rent a domain name from a domain registrar (like Namecheap, GoDaddy, or Squarespace — formerly Google Domains). You pay an annual fee (about $12/year for a .com). As long as you pay, it’s yours.

Your domain name is also your email address (you@contosoplumbing.com instead of contosoplumbing@gmail.com). A custom email address looks far more professional than a Gmail address.

The 7 Rules of a Good Domain Name

Rule 1: .com first, always

The .com ending is what people assume. If you say “go to my website, it’s Contoso Plumbing,” they’ll type contosoplumbing.com — not .net, .biz, or .io. If your .com is taken, try harder to find a .com variation rather than settling for a different ending.

Exceptions: If you’re a non-profit, .org is appropriate. If you’re a school, .edu. For everyone else, fight for the .com.

Rule 2: Short (under 15 characters if possible)

The shorter the better. contosoplumbing.com is good. contosoplumbinganddrainservicesofaustintexas.com is not. Every extra character is another chance to mistype.

Under 15 characters (before the .com) is ideal. Under 20 is acceptable. Over 25 is too long.

Rule 3: Easy to spell over the phone

If you say your domain name out loud — to a customer, on a voicemail, in a radio ad — can they spell it correctly? “Contoso Plumbing” is easy. “Café Résumé Services” is not (accents, hyphens, special characters).

Avoid words with multiple spellings (is it “gray” or “grey”? “doughnut” or “donut”?). If your name has an ambiguous spelling, consider using initials or a shortened version.

Rule 4: No hyphens

contoso-plumbing.com is harder to say, harder to type, and looks less professional. When you tell someone your domain, you have to say “contoso dash plumbing dot com” — and they’ll forget the hyphen.

Hyphens are also associated with spam websites. Google doesn’t penalize hyphenated domains, but visitors trust them less.

Rule 5: No numbers

contosoplumbing247.com — is that “two four seven” or “two hundred forty-seven” or “247”? When spoken, numbers create ambiguity. If someone hears your domain on a podcast or voicemail, they may type it wrong.

Exceptions: If your brand identity IS a number (e.g., “7-Eleven”), it’s unavoidable. But in most cases, spell it out or omit it.

Rule 6: Memorable and brand-aligned

Your domain should match your name as closely as possible. If you’re “Contoso Plumbing,” contosoplumbing.com is perfect. bestplumberinyourarea.com is generic and forgettable.

If your exact name is taken, add a word that clarifies: contosoplumbingaustin.com or contosoplumbingservices.com. The word should add clarity, not length.

.io, .xyz, .ninja, .guru — these endings were trendy for tech startups but confuse regular visitors. A plumber doesn’t need contosoplumbing.io; they need contosoplumbing.com. Trendy endings age poorly and reduce trust.

Some tech companies use .io successfully, but context matters. For most sites serving non-technical visitors, .com is the right choice.

What to Do If Your Domain Is Taken

Don’t panic. Practical strategies, in order of preference:

  1. Add your city or region: contosoplumbingaustin.com — clarifies location and helps local search.
  2. Add “services” or a descriptor: contosoplumbingservices.com — adds clarity without much length.
  3. Abbreviate: contosoplumb.com — only if it’s still clear and recognizable.
  4. Use your full name: If “Contoso Plumbing” is taken, try contosoplumbingco.com or contosoplumbingtx.com.
  5. Consider a different name: If nothing works, your name might be too generic. A more distinctive name makes domain selection easier.
  6. Don’t buy a premium domain: Someone may be selling contosoplumbing.com for $5,000. For most people, this is almost never worth it. Spend the money on your website, not your domain.

How to Check If a Domain Is Available

Go to a domain registrar (Namecheap, GoDaddy, or any registrar). Type your desired domain name. If it’s available, register it immediately — domains are first-come, first-served. Someone else can grab it while you think about it.

If it’s taken, the registrar will suggest alternatives. Use the strategies above instead of the registrar’s auto-suggestions (which often include hyphens and non-.com endings).

Domain Registrars: Where to Buy

  • Namecheap: Good prices, free WHOIS privacy, simple interface. Recommended.
  • GoDaddy: Well-known but tries to upsell heavily (email, hosting, SSL, website builder). The domain itself is fine; just decline the extras.
  • Cloudflare Registrar: At-cost pricing (no markup on domains), free WHOIS privacy. Good if you already use Cloudflare.
  • Squarespace (formerly Google Domains): Clean interface, slightly higher prices, good if you want simplicity.

Whoever you choose, make sure they include WHOIS privacy (keeps your personal information — name, address, phone — out of public records). Most good registrars include this free.

Common Domain Mistakes

  • Registering through your web developer’s account — If your developer registers the domain under THEIR account, they own it, not you. Always register the domain yourself, or make sure it’s in your name with your email as the registrant.
  • Letting it expire — Domain renewals are annual. If you forget to renew, someone else can buy your domain. Set up auto-renew.
  • Buying unnecessary extras — Registrars will try to sell you hosting, email, SSL certificates, “premium DNS,” and website builders. You usually don’t need any of these from your registrar. Just buy the domain.
  • Choosing a domain you can’t say easily — Say it out loud. If it sounds awkward or requires spelling out, pick another.

FAQ

How much does a domain name cost?

A .com domain typically costs $10–$15 per year. Some registrars offer a discount for the first year ($1–$5) but charge full price on renewal. WHOIS privacy (keeping your personal info out of public records) should be free — avoid registrars that charge extra for it. You own the domain as long as you pay the annual renewal fee.

Can I get a free domain name?

Some website builders (Wix, Squarespace) offer a “free” domain for the first year when you pay for their annual plan. But you don’t own the domain — the builder does. If you leave their platform, you lose the domain. It’s better to buy your domain independently from a registrar and connect it to your website. This way, you own it regardless of which platform or developer you use. Read more about Wix vs Squarespace vs a developer →

Should I buy multiple domain extensions (.com, .net, .org)?

If you’re growing and want to protect your brand, buying the .net and .org versions of your domain prevents competitors or squatters from using them. But for most sites, the .com is sufficient. Don’t buy 10 extensions — it’s unnecessary expense. If budget allows, buy .com and .net. That’s enough.

What if someone is cybersquatting on my name?

If someone has registered your name as a domain and is trying to sell it to you at a premium, you may have legal recourse under the Uniform Domain-Name Dispute-Resolution Policy (UDRP) if you have a trademark. However, legal action is expensive and slow. For most people, the practical solution is choosing a variation (adding your city or “services”) rather than fighting for the exact domain.

Bottom Line

Your domain name is the foundation of your online presence — it’s on your business cards, your email, and every Google result. Choose .com, keep it short, make it easy to spell, and register it yourself so you own it. Read more about how long it takes to build a website →
