.net, .biz, or .co: What Each One Says to Your Customers

The name you want is taken. It happens to almost everyone. So the registrar shows you the same name with a different ending: .net, .biz, or .co. They all cost about the same. They all work the same way in a browser. So does it matter which one you pick?

Yes. Not to a search engine—to a person. The ending after your name is the last thing a customer reads before they decide whether to trust it. Here's the real difference between .net, .biz, and .co for business, told plainly.

What each ending says without saying it

Your domain ending sends a quiet message. Most people can't explain it, but they feel it. Here's what each one tends to say.

.net — "we've been around a while"

.net is old. It came out at the same time as .com, back in the 1980s. For years it was used by internet and phone companies—the "net" stood for network. Today most people read .net as a slightly older, slightly more technical cousin of .com.

It doesn't look cheap or fake. If a customer sees joneselectric.net, they'll type it and move on. The only risk is confusion: if joneselectric.com belongs to someone else, some of your customers will land on their site by mistake. That's the main thing to weigh with .net.

.biz — "budget option" to a lot of people

.biz was created in 2001 to give businesses another choice when .com names ran out. On paper, that sounds fine. In practice, .biz got used by a lot of low-quality and spam sites over the years. Many people now read it as a second-choice ending.

That's not fair to every .biz owner, but it's the reflex you're working against. If you run a business where trust matters a lot—a clinic, a law office, a contractor asking to come inside someone's home—.biz can make a customer pause. For a lot of local businesses, that pause isn't worth it.

.co — "a real company" if you spell it right

.co is the newest of the three. It's short, it reads like "company," and plenty of well-known brands use it. Younger customers barely blink at it.

The catch is the same one that follows every ending that looks close to .com: people forget the missing "m." Say your address out loud enough times and some folks will still type .com out of habit. If you go with .co, you'll want to say it clearly—"dot C-O"—every time.

So which one should you use?

Here's the short version.

• .net is the safest of the three. It looks established and nobody thinks less of a business for using it. Just make sure you know who owns the matching .com.
• .co is a good modern choice, especially if your customers skew younger or you're comfortable spelling it out loud. It's clean and short.
• .biz is the one to be careful with. It can work, but it starts you a step behind on trust for no real upside.

None of these hurt you with Google. The ending you choose doesn't change how you rank. We wrote about that in does your domain ending change how you rank on Google—the short answer is no, so pick the ending based on people, not search engines.

Before you settle for a different ending

A different ending is one way to handle a taken name. It's not the only way. Sometimes a small change to the name itself gets you a .com that's easier to say than any .net or .co of the original. Adding your city or your trade often does it—austindeckbuilders.com instead of deckpros.net.

If you're set on the exact name you had in mind, read is a .com still worth it when the name you want is taken before you decide. And if you're wondering how much any of this changes what a customer thinks, do customers trust .com more than newer endings lays out what actually moves the needle.

The one test that beats all the rules

Say the whole address out loud to someone who's never heard it. Then ask them to type it. If they get it right on the first try, the ending is fine—whatever it is. If they hesitate, add a "dot com?", or spell it back to you wrong, that's your answer.

A name only works if a customer can hear it once and find you. That matters more than which of these three endings you land on. Pick the one people can repeat.

If you want to check which endings are still open for a name, most registrars let you search for free—ICANN's overview of domain names explains how the whole system fits together if you're curious.
