A good domain name is vital to a successful internet brand managment. The .com domain remains foremost in the public mindset. (Nearly 73% of all domain registrations are .com with .net in second place at less than 11%.) If you’re serious about marketing your business online, choose a .com as your primary domain. It’s also important to have something short and memorable. Try to avoid anything with cryptic acronyms or special characters that aren’t immediately idenitified with your brand. Keep it simple and make life easy for you and your audience!
Most domain names are pretty inexpensive, and a good domain name can save you thousands of dollars in marketing and advertising, whether online or otherwise.
