Make sure your domain is easy to spell and pronounce, and doesn’t contain any strange letter substitutions or omissions that will make it difficult to remember. Hyphens are also usually not a great idea because people forget about them
Domain and Brand
If you already have a business or brand, your domain should match your name. If the .com domain is taken, you can try an alternate TLD, but be sure not to put yourself in another company’s shadow or infringe on their trademark.
Short and Sweet
Keep the domain names as short as you can manage. Single-word domains, when you can find one, are golden.
Check that the domain name does not appear as a username on major social media sites like Facebook, Twitter, and Instagram.
