A domain name is the name of a server that distinguishes it from other systems on the World Wide Web. There are top-level domains, such as .com, .org or .tv, and mid-level domains such as Amazon, eBay or TheSearchAgency. When combined, these two levels create the domain name (i.e. TheSearchAgency.com), which points to the IP address of the server. A domain name relevant to a user's query may aid in improving search ranking.
