What Makes a Good Domain Name?

The best domain names are short, memorable, and easy to spell out loud. If you have to explain how to spell it, it's already working against you.

Avoid hyphens. Avoid numbers. And for the love of everything, don't swap a zero for the letter O just because the real name is taken. Nobody types "c0olbrand.com" on purpose — they just end up on your competitor's site.

Stick to real words or clean combinations. If someone can't remember it after hearing it once, it's not doing its job.

A .com is still king. People default to .com out of habit. If you can't get the .com, ask yourself whether the name is really the right one — or whether it's worth the confusion.

Short enough to fit on a business card. Simple enough to say on a phone call. That's the bar.

Domain Extensions Available for Purchase

gTLDs (generic top-level domains) — the open-to-everyone category. Think .com, .net, .org, .xyz, .app. No restrictions, no paperwork, just pick a name and go.
ccTLDs (country-code top-level domains) — two-letter codes originally tied to specific countries, but many have gone global. .io, .co, and .me are technically country codes that the whole internet adopted anyway. Fun fact: .gg is technically Guernsey's domain, but gamers have claimed it as their own (and registrars know it, because it is not cheap).

You Probably Can't Buy Any of These

sTLDs (sponsored top-level domains) — reserved for specific communities with eligibility requirements. .edu is for accredited schools, .gov is for government agencies, .mil is for the military. Unless you fit one of those boxes, these aren't happening.
grTLDs (generic-restricted top-level domains) — open in theory, but come with strings attached. .pro requires proof you're a licensed professional, .name is meant specifically for personal names with its own registration rules.
tTLDs (test top-level domains) — purely for technical testing behind the scenes. Not registrable by anyone, ever. These exist so engineers can test things without breaking the real internet.

Understanding Domain Extensions

.com

The original and still the gold standard. If you're building a brand, business, or anything customer-facing, .com is instantly recognizable and trusted. Most people type ".com" out of habit, so owning it means you're not losing traffic to confusion.

.net

Originally meant for "network," now widely used as a solid alternative when the .com is taken. Still feels professional and credible, especially for tech, software, or service-based businesses.

.org

Traditionally associated with non-profits, organizations, and communities. If your project has a mission-driven or community feel, even if it's not a registered non-profit, .org signals trust and purpose.

.io

Popular with startups, developers, and tech products. ".io" reads as modern and technical, originally the country code for the British Indian Ocean Territory, now adopted globally by the tech world. It's a go-to choice if .com is taken and you want a startup feel.

.co

A short, clean alternative to .com, often used by startups and brands going for a modern, minimalist look. Originally Colombia's country code, now used internationally as shorthand for "company" or "corporation."
