A domain name uniquely identifies a website and is often referred to as a website’s online home or real estate. Typing a domain name (also called a URL) into a browser allows a user to directly access that site.
 
Your domain name is literally your online identity and impacts the perception that users and searchers will have of your site. It should be easy to remember, should use the best domain extension for the type of site you own.
