What makes a great domain name?
Choosing the right domain is critical for your website. When you combine it with the right extension, it becomes even more powerful.
Relevant
Your domain name should connect to your brand, business, and web content. It should give visitors a clear idea of what to expect when they land on your site.
Memorable
Great domain names stick in people's minds and stand out from the crowd. Avoid complex or confusing words that challenge spelling.
Short
Short domains are easier to remember and type. Avoid unnecessary words or hyphens that can make your domain name hard to remember.
On-brand
Your domain name and extension offer an opportunity to reinforce your brand identity. Extensions and TLDs specific to your industry can enhance the relevance and credibility of your website.

Domain Name Search FAQs
What is a domain name?
A domain name is the address you type into your web browser to visit a website, like "instantdomainsearch.com." It identifies a website on the internet, making it easy for people to find and remember. Like your home address helps people find where you live, a domain name helps people find your website. Our domain search tool helps you find available domains.
Why use Instant Domain Search?

What if the domain name I want is already taken?
If someone already owns the domain name you want, you still have several options:
- Try a different extension: if someone owns "example.com," check if "example.net," "example.org," or other TLDs remain available. See the full list of available extensions.
- Create a variation: add a word, hyphen, or change the order of words to create a variation of your desired domain name. Our Domain Name Generator suggests similar available domains. Our premium domain search tool also helps you find similar, high-performing domains.
- Contact the owner: the current owner might sell their domain. You can often find owner information by visiting the domain or using a WHOIS lookup tool to locate the owner.
How do I check if a domain name is available?
Use our domain name search tool to see if a domain name is available. Type the name you want, and you'll receive real-time results with instant checking for different extensions (like ".com" or ".net") and alternative suggestions.
What are extensions and TLDs, and which one should I choose?
A TLD (Top-Level Domain) represents the part of a domain name that comes after the dot, like ".com" or ".org." The .com extension ranks as the most common, but many others, such as ".net" or industry-specific extensions like ".tech" or ".shop," offer great alternatives. Our domain extension tool helps you explore different TLD options.
How do I buy a domain?
Once you find an available domain using our domain name search tool, select a registrar to purchase it. We show you pricing from trusted registrars so you can buy with confidence. After buying, you'll connect the domain to your website or hosting provider.
