Your website domain is the equivalent of the address of your business location. Without a domain, you do not have a website. The domain is the web address for your Internet presence and it is something that you purchase once and then update on an annual basis. Most website owners actually renew their website for several years at a time to help improve its standing in search engine results pages.
The other name for a domain is URL and it is made up of the name and top-level domain designation. For example, greatmarketing.com has a name of great marketing and a top-level domain designation of “.com.” There is a variety of top-level domain designations to choose from and most marketers will tell you that buying as many top-level domains as possible will help to protect your website URL from anyone who may want to steal your web traffic by using a name that is similar to yours.
