A domain name is your website's name, for example the domain name for us is "wehostweb.ca" . A domain name needs to be registered before you can use it.
A domain name can be any combination of letters and numbers, and it can be used in combination of the various domain name extensions, such as .com, .net and more. Our favorite ones are .com ($14.99) and .ca ($15)
Every domain name is unique. No two websites can have the same domain name. If someone types in www.yourdomain.com, it will go to your website and no one else's.
You can find all the different extensions availableand prices @ https://wehostweb.ca/domain
Once you have registered a domain name, you will need web hosting to get it online!
