How to choose and register a domain name

Your domain name is the foundation of your brand identity online. It’s often the first thing people remember, which means making the right choice can instantly boost credibility and trust.

A strong domain can also support SEO by making your site easier to understand and your brand easier to recognize in search results. When you register a domain, you’ll need to make a few key choices, such as choosing a domain registrar, turning on privacy protection, and confirming what your WHOIS lookup information will display.

In this domain registration guide, you’ll learn how to choose and register a domain name, and what to do after you buy one, such as setting up an SSL certificate and updating DNS settings (name servers and your DNS provider).

To successfully choose and register a domain name, you must follow key steps:

• Brainstorming different domain names
• Checking domain availability
• Selecting a Top-Level Domain (TLD)
• Completing domain registration
• Connecting it to your website

Step 1: Brainstorm relevant keywords

For domain name selection, start by brainstorming keywords that describe what you do, who you serve, and what makes your brand different. This is a lightweight form of keyword research. Here, you’re looking for words your target audience already uses. The goal is to find a few strong, brand-relevant terms that instantly signal what you’re about and feel credible in your space.

To keep your ideas aligned with your brand identity, list words that match your tone, your category, and your audience (B2B vs. consumer). Then mix and match: pair a core keyword with a brand word, benefit, location, or signature method until you have a short list of possible brand options.

Tips for effective keywords

Here are some of the best domain name tips to help you keep your keywords clean, brandable, and easy to use.

• Keep it short, memorable, and easy to spell ( less than 15 characters). Short names are easier to type, share, and remember. A simple, clean domain name reduces typos and makes it more likely people return directly to your site without having to Google you again.
• Avoid numbers and hyphens. Numbers create confusion, and hyphens are often forgotten or misplaced. Both increase the chance someone lands on the wrong site or fails to find you at all.
• Check trademark conflicts via USPTO or local registries. Even if a domain is available, the name might already be legally protected. A quick trademark check can help you avoid rebranding later, losing a domain you’ve built marketing around, or dealing with cease-and-desist issues once you start gaining traction.
• Leverage domain names and cloud domains to inspire modern, tech-savvy names. Competitors often use these phrases because they match how people search. You don’t want to copy them, but you can use them as creative cues. For example, you can pair a brand word with cloud, host, labs, stack, or studio to create a domain name that feels current and relevant.

Step 2: Check domain availability

Once you have a short list of domain name ideas, the next step is to confirm if it’s available. Start by searching your preferred name with a domain registrar’s search tool. If your exact match isn’t available, you’ll often see close alternatives.

You can also use a WHOIS lookup to see who currently owns a domain and whether it might be available soon. WHOIS records can show registration and expiration details, as well as ownership information.

If you want a simpler option, Wix’s built-in domain search shows real-time availability as you type, suggests alternatives when your first choice is unavailable, and can surface options like premium TLDs that might fit a more modern or niche brand. That way, you can compare extensions and choose the best domain registration name before someone else takes it.

Interpreting search results

• Exact match vs close enough names. If your exact match is available, that’s a great sign. If it’s taken, you’ll see similar suggestions (extra words, alternate endings, slight spelling changes).
• Country-code TLDs (ccTLDs). A TLD (top-level domain) is the ending after the dot in a domain name, such as .com, .net, or .org. A country-code TLD (ccTLD) is a TLD tied to a specific country or region, such as .gr (Greece), .uk (United Kingdom), or .de (Germany). Note that while a ccTLD is great for local SEO and branding, it can be limiting if you plan to market globally later.
• .com vs. .net vs. newer TLDs. In many industries, .com is still the default because people naturally type it. .net can be a solid backup (especially for tech), while newer extensions (including some modern, cloud, or tech-sounding options) can be brandable if they fit your audience. The key is clarity. Choose a TLD that won’t make people second-guess your site.
• What this means for SEO. Your domain name doesn’t need to be keyword-stuffed to rank; what’s more important is brandability and trust. A clear, credible domain helps people click, remember you, and link to you, which, in turn, supports SEO. Also, if you’re choosing between similar options, pick the one that’s easiest to say out loud and type correctly.

Most tools use wording like “Register domain” or “Register this domain,” which is your signal that the name is available for domain registration with that registrar. If it’s unavailable, you’ll typically see alternatives or a prompt to search again.

Step 3: Choose the right TLD

Your TLD (top-level domain) is the extension at the end of your domain name, such as .com or .org, and it subtly shapes how people perceive your brand. The right choice depends on your audience, your industry, and how you plan to market the site.

.com (the default for most brands)

If it’s available and affordable, .com is usually the best choice for branding and credibility, since many people assume it by habit. It’s also the easiest to say out loud, write on a business card, and share without explaining.

.org (mission-driven and community-focused)

.org is widely associated with nonprofits, initiatives, and public-interest projects. It can build trust for mission-led brands, but it may feel misleading for a purely commercial business.

.biz (business-forward, but less common)

.biz clearly signals business, but it’s less standard than .com. It works best when your exact .com is unavailable, and your audience won’t be thrown off by the extension.

Niche TLDs (.tech, .store, .io, and more)

Niche extensions can be highly brandable when they align with what you do (.store for ecommerce, .tech for software and IT, and .io for startups and tech products). They can help your domain feel modern and specific, but only if they’re easy for your audience to recognize and remember. If you’re choosing between a niche TLD and a slightly awkward .com, prioritize whichever one is clearer, more trustworthy, and easier to say and type.

Wix offers 400+ domain extensions, including discounted premium TLD options and, in many cases, a free .com with annual plans, plus bundled SSL to secure your site from the start.

Step 4: Register your domain

Once you’ve picked an available domain name and the right TLD, it’s time to register your domain with a domain registrar. This is where you officially claim the name for a set term. You’ll enter basic contact information for the domain registration record, choose any add-ons, and complete payment. After that, the domain is yours as long as you keep renewing.

During registration, you’ll need to confirm the domain name you’re buying, the registration length, and whether you want privacy protection (so your personal details aren’t publicly visible in a WHOIS lookup). Some registrars also offer extras, such as email hosting or DNS management.

With Wix domain registration, your domain can auto-connect to your Wix website (so you don’t have to manually adjust DNS settings and name servers). You’ll also get a free SSL certificate, and you can enable WHOIS privacy at no extra cost.

Protecting your domain

Protecting your domain helps prevent three common problems: unauthorized changes (hijacking), accidental expiration, and unwanted exposure of your contact details.

• Enable privacy protection (WHOIS privacy). This replaces your personal info (such as your name, email, phone number, and address) in public WHOIS records with proxy details, reducing spam and helping keep your identity private.
• Turn on auto-renew. If a domain expires, someone else can register it. Auto-renewal is the simplest way to avoid losing your domain name. Try placing a backup reminder in your calendar.
• Lock the domain. Domain lock prevents unauthorized transfers and adds a layer of protection against someone moving your domain to another registrar without permission

Wix includes WHOIS privacy by default and sends renewal reminders, which helps you stay protected and avoid lapses in domain registration.

Step 5: Connect the domain to your website

After you register a domain, you need to point it to your website so it actually loads the right site. This happens by flicking through the DNS settings.

Depending on where you bought the domain, you’ll connect it either by updating name servers (handing DNS management to your website platform) or by editing DNS records manually at your registrar. If you don't yet have a site, you can easily create one with Wix and then connect your domain directly to the platform.

DNS basics (A-record and CNAME)

An A-record points your root domain (like yourdomain.com) to an IP address, which tells browsers where the site lives. A CNAME record usually points a subdomain (like www.yourdomain.com) to another domain/host name, so “www” routes correctly too. Most setups use both to allow your site to work well with and without “www”.

Verification

Some platforms ask you to verify ownership before the connection goes live. This typically means adding a TXT record (a short verification code) or a specific CNAME record in your DNS settings to prove you control the domain.

Propagation time

DNS changes aren’t always instant. After you update records or name servers, it can take anywhere from a few minutes to 24 to 48 hours for changes to fully reflect worldwide. During this window, the domain may work for some people but not others.

Wix offers one-click domain connection in the Wix Dashboard, allowing your domain to auto-connect to your site without manual DNS configuration (no editing A or CNAME records required).
