ドメイン選びのヒント
短く保つ
6〜14文字を目安にしましょう。短いドメインは覚えやすく、入力しやすく、名刺にも収まります。
スペルしやすく
複雑なスペルや、複数の綴り方ができる単語は避けましょう。
数字やハイフンは避ける
これらはドメインを口頭で伝えにくくし、プロフェッショナルに見えない場合があります。
長期的に考える
ビジネスの成長を制限しない名前を選びましょう。過度に具体的な地名や製品名は避けてください。
商標を確認
決定前に、既存の商標を侵害していないか検索で確認しましょう。
素早く行動
良いドメインはすぐに登録されます。理想のドメインを見つけたら、すぐに確保しましょう。

Frequently Asked Questions
About the Domain Generator
The Domain Generator takes the hard part out of finding a short, brandable, genuinely available web address. Describe what you have in mind in a few words and it returns a curated set of ideas you can act on immediately, instead of staring at a blank page.
Great names rarely arrive on the first try. The real work is producing enough strong candidates to choose from, then narrowing down with a clear head. This tool handles the first half — the volume and variety — so you can spend your energy on the decision that matters.
Use the suggestions below as a starting point rather than a final answer. The best domain is usually the one you tweak, combine, or build on after a few rounds. The tips and answers that follow will help you judge each option and pick with confidence.
Tips for choosing the perfect domain
Favour .com first
A .com still carries the most trust and direct-type traffic. Check it before falling in love with an alternative extension, and treat newer TLDs as a backup rather than the goal.
Keep it under three syllables
Shorter names are easier to spell, share out loud, and recall. If a friend cannot type it correctly after hearing it once, it is probably too long or too clever.
Start with meaning, not letters
Begin from the idea you want to convey — the feeling, benefit, or theme — and let the words follow. Names built on a clear concept are far stickier than random letter combinations.
Generate widely, then cut hard
Volume beats agonising over a single option. Produce a long list quickly, then ruthlessly remove anything hard to spell, easy to confuse, or already taken.
Test it on real people
Show your top few to people outside your head. Watch whether they can spell it back, remember it an hour later, and pronounce it the way you intended.
Avoid trendy spellings
Dropped vowels and clever respellings feel fresh today and dated tomorrow, and they cost you every time someone types the obvious version instead.
Picture it everywhere
Imagine the name as a logo, a URL, a signature, and a headline. A good name works small and large, in print and out loud, without explanation.
Frequently asked questions
Is the Domain Generator free to use?
You can generate ideas to explore the tool, and a free account includes monthly credits so you can try it without paying. Heavier use and premium options draw from your credit balance, which keeps results fast and high quality for everyone.
How does the Domain Generator come up with ideas?
It reads the meaning behind your prompt rather than just matching keywords, then blends proven naming patterns with fresh combinations. That is why a short description of your domain returns options you would not have reached by brainstorming alone.
How many results will I get?
Each run returns a generous batch of scored suggestions so you can compare quickly. If nothing clicks, refine your description with a little more detail and run it again — small changes to the prompt produce noticeably different directions.
Can I use the names commercially?
The generated suggestions are yours to use. Before you build a brand on one, do the usual checks — trademark databases and availability — because the tool cannot guarantee that a given name is unregistered in your industry or region.
What makes a good domain?
The strongest options are easy to say, easy to spell, and easy to remember, with a sound that fits the impression you want to make. Aim for something distinctive enough to stand out yet simple enough that nobody has to think twice.
What should I do after I find one I like?
Shortlist two or three, say each aloud with its full context, and sleep on them. Confirm the name is available where it matters to you, then commit — the option that still feels right a day later is usually the one to choose.
