Purchasing a domain name gives you your presence on the Internet and it gives you an address that people can type to find your business. Purchasing a domain name is not a one time purchase, it is something that must be renewed after a period of time, depending how long of a term you purchase initially. Here are some things to keep in mind. First make sure your domain name is memorable and easy to type, this is critical to success online. Keep it short and avoid numbers and hyphens. If your domain name too complex you will risk loosing customers due to misspellings or mistypings. Be sure that you use keywords that are important to your business and your target area. Finally, Do some research! Check out other businesses in your industry and see what kinds of names they are using. Make sure you choose wisely before you end up putting alot of effort into something that will need changing later.
