Your domain name should be your business name, related services, or mention your business in some way. That’s the key to successful branding and having people remember you.
Make it Easy To Remember! Keeping it simple is the key to a great domain name, so avoid long words, slang or technical terms. If you have a great site that people can’t remember how to get to, then that doesn’t help you at all.
Your domain name should be unique, since you want to stand out from the competition. Don’t choose domains that are exactly the same as another domain but with a hyphen added in the middle or an s at the end. If someone tells their friends about your site, you want to be sure that they make it to the right one.
