What makes a good domain name?
A good domain name is short, spells the way it sounds, and matches your brand name as closely as possible. The practical ceiling is around 15 characters - beyond that, typos increase and the name becomes harder to share verbally. Every character you cut reduces friction for every customer who ever types your address from memory.
The extension still matters. .com remains the default expectation for US businesses. When someone hears a company name in conversation, on a podcast, or in an ad, their first instinct is to type it with .com. Choosing a different primary extension means fighting that instinct every time. Other extensions (.io, .co, .ai) are increasingly accepted in tech and startup contexts, but they require more active communication to establish - “it’s getnotion dot io” rather than just “notion dot com”.
One underused strategy: if your ideal .com is taken by an inactive or unrelated business, consider adding a short prefix or suffix (“get”, “use”, “hq”, “app”) rather than switching extensions. “GetNotion.com” loses less brand value than “Notion.io” for most audiences.
Haven’t settled on a business name yet? Start with the business name generator first, then come back here to turn the name into a domain. If you don’t need the AI-specific angle, the standard domain name generator covers the same availability workflow for any brand. It’s also a free AI domain name generator, so there’s no reason not to run it a few times before you commit.
How to find the right domain name with the generator
This AI name generator produces better results with a specific brief. “Premium project management tool for remote engineering teams” will return more distinctive and available domains than “project management software”. The more context you give it about your audience and differentiator, the more targeted the suggestions.
When evaluating suggestions:
- Say it aloud without spelling it. If the other person has to ask how it is spelled, that name will cost you traffic and word-of-mouth every time it is mentioned verbally.
- Check .com availability. As an AI domain name generator and checker, NameCraftr checks .com in real time for every suggestion. Prioritise names where the .com is available - it is the asset worth protecting first.
- Google the exact domain. Is there anything at that domain already? Existing content, a dormant business, or a controversial association? Check before registering.
- Check for trademark conflicts. A domain can be available to register while still being protected by an existing trademark. Search tmsearch.uspto.gov for your class of goods or services before investing in the name.
After the generator: securing your domain
Once you have a name you want:
- Register the .com immediately - before announcing the business, building the website, or sharing the name publicly. Domain squatters watch registrar searches.
- Register .co and .io defensively if your market makes those extensions plausible alternatives that competitors or copycats might use.
- Set up domain privacy (WHOIS protection) through your registrar to keep your personal contact details out of public WHOIS records.
- Enable auto-renewal on every domain. A lapsed domain is one of the most avoidable crises a business can face - you lose email, your website goes dark, and the name becomes available to anyone.
- If you plan to trademark your business name, file with the USPTO promptly after securing the domain. Your trademark rights date from the filing date, not the domain registration date.
Consider registering common misspellings of your domain and redirecting them to the correct address. For every character that is commonly transposed or swapped, a redirect catches customers who would otherwise land nowhere.
Common domain naming mistakes
Choosing a non-.com extension to avoid paying for a premium .com. Premium .com domains can be expensive, but a .com with a short modifier (“get”, “use”, “hq”) is almost always better than a clean non-.com. The trust and recall advantage of .com compounds over years.
Registering a domain that infringes an existing trademark. An available domain is not necessarily a legally safe domain. A trademark holder can file a UDRP (Uniform Domain-Name Dispute-Resolution Policy) complaint and recover a domain you registered - even years after you built a business on it. Always run a trademark search.
Using hyphens to get an unavailable name. If “brightpath.com” is taken and you register “bright-path.com”, customers who hear the name will go to the unhyphenated version. Hyphens also look less credible in email addresses. If the clean version is unavailable, generate a new name rather than hyphenating.
Waiting to register secondary extensions. Many businesses register .com and plan to “get the others later”. By the time they return, squatters have often taken .co, .io, or .net. Register defensively on day one.
