The Difference Between a .com and a .com.au Domain
Last Updated: 25 October 2006
We get asked a lot whether you should
obtain either a .com or a .com.au domain name
when building a website in Australia. Here's the
answer.
What's the difference between a .com. and a .com.au name? Basically, a .com.au domain name identifies you as an Australian business. This has a number of advantages if you are targetting Australian Internet users.
Probably the most important effect a .com.au domain has is that some search engines filter their results according to where the searcher lives. For example, if you conduct a search on Google, it is clever enough to work out where you are. And when it knows that you live in Australia, it will often make the assumption that you will be more interested in Australian websites, and so it may place Australian websites higher up the search results than international ones.
This isn't always the case, but over time you will find that depending on your product, .com.au domains may rank higher in Australia than international domain names. This is important if your market is solely in Australia.
What if your market is global? Then a .com may be more appropriate for you. For example, our domain name is a .com domain, because we can and do provide our services worldwide, even though we are an Australian business based in Australia. We want to be recognised as a global Internet business and so we chose the .com domain.
