A Domain name is a string of words that identifies a website.We should be very careful with the naming conventions
* The domain name is very important for any business and it should be easy to remember without much punctuations.
* It should be unique and related to business.
* It should be short and catchy.
* If it is of universal accepted TLD's like .com,.biz,.info
In choosing the registrar also one should be very careful.The registrar should be reliable and provide services at affordable cost.I chose http://www.9cubehosting.com/cheap_domains/ since the cost is low when I get the domain registration and hosting as a package from them.
