A domain is your website’s address on the internet - what people type into their browser to reach your site (for example, google.com).
Every domain name is unique, which means no two websites can use the exact same domain. When you own a domain, you are reserving that online address so people can find the website connected to it.
A domain name can include letters and numbers and is combined with a domain extension such as .com, .net, .org, and many others. To use a domain, it must first be registered.
