1. Choose a short name, Although you can register a name with up to 63 characters, you have to keep in mind that people need to be able to remember it, and easily type it into their browser. Try to register a short and easy name that your customers and visitors will associate with your Website.
2. Using your company name is usually the best idea. Try and avoid hyphens and special character names even if the name is long.
3. There are many different extensions available right now. For businesses, I would recommend a .com extension. It is the first extension that most people try when searching for a website. Also it is one of the most popular extensions.
4. Avoid Trademarked Names because you may land in trouble if the particular company to whom the trademark belongs takes a legal action on you. Also the trademark name may not be very useful to you and your business.
5. You can also register similar domain names with different extensions. If you have "yourname.com" you should register "yourname.net" too. You donโt need a separate web page for each of those names, several domains can point to the same website.
6. When you have selected a few available names, see what your friends and clients have to say . It is possible that a name that may make perfect sense to you but may be too hard for them to remember. You should take their opinions on your domain whether it is easy to remember and spell?
