Enhance Your Marketing and Visibility
The good domain name allows people to remember and find you easily. It's your visual address on the web and your email address.   For example, zongji.net would be a good name if you have a car business.

Build Credential
The personalized email address using your domain helps establish credibility and professionalism. For instance, an email address such as [email protected] is more professional than [email protected]

Protect Your Brand
Acquire the domain name that best represents your business. Domains are valuable online real estate. Secure the right name and keep it out of the others.

You may also find many related domains for your business. Obtaining more than one helps secure your brand and increase your market reach. You can have as many domains as you want for your business.  For example, you can redirect the traffics the go to buynow.com to your website – whatbuy.com.

For Investment
Domain names are like real estate.  They increase in values. Given the limited good domain names available and the growing of the world population, good domain names are becoming more valuable.  For example, someone names “John” may want to build his personal website using his name as the domain names, but there are many John available in the world and only few John.xxx (such as John.com, John.bz) available.
