A domain name is your website address on the internet and gives you an online identity or brand. It’s a valuable part of your business identity and is an important marketing tool that can help customers find and identify with your business.

A domain usually looks like this:


The components of a URL (website address) are:

  • http:// – this is code and means that it is an address on the internet. This is used by various software. For example, your email client will know when you click on a link with http:// to open up your web browser and go to that link.
  • https:// – the “s” means it has “SSL” installed. This encrypts the data between the server (website) and the end user’s browser. This is best practice for all websites and required for any financial transactions
  • www – means world wide web which is the main part of the internet. This section is not relevant and i have stopped using this.
  • customname – this is your custom name that you choose.
  • com – this is the domain (Top Level Domain)



Domains represent a country, organisation or organisation type. There are many different domains (see this list). Many domains have rules and restrictions and cannot be used while some have very few restrictions.

  • .net    .com   .org are the easiest to register
  • .com.au are for Australian brands and organisations. There are more Australian domains available.
  • .org.au  requires a registered organisation
