Have you ever asked yourself, "What is a domain, anyway?" Well, take a look up there at the top of the screen. See that part at the top of your browser window in the URL bar? It's the part that starts with "https://" in the address bar. The second part of the URL is the domain. In our case, it's freeonlineseoadvice.com. A domain name is a label that identifies a network domain: a distinct group of computers under a central administration or authority. Within the Internet, domain names are formed by the rules and procedures of the Domain Name System. Any name registered in the DNS is a domain name. There are 330 million domain names that are registered in the world (2019), and the list continues to grow. Choosing the right domain name for your website is crucial for your success. If you choose the wrong domain name, then it can be a hassle to switch later on without hurting your brand and search rankings. That's why it's extremely important that you choose the best domain name from the start.
