1. Why Choose a .AU Domain?

There are several advantages of using a .au domain name over other domain extensions.

Improve Australian online presence

Search engines consider location when giving search engine results page (SERP) rankings. By using a local Australian domain, you give these programs vital data about your business address. Thus, your site is more likely to get a good search ranking, especially when it comes to local search queries. This translates to higher online traffic, leads, and conversion rates.

Boost credibility

Around 96% of Australian consumers prefer locally produced or sourced products and services. This is not only because of nationalism but also the established brand credibility of Australian-manufactured merchandise. Using a site with a .au domain name means that you have met the .au Domain Administration (auDA) criteria. It will help make your brand trustworthy and allow you to penetrate even larger markets.

Enhance security

Phishing, fraud, scams, and other forms of malicious activities are rampant in the online space. This is especially true in the United States where the Federal Bureau of Investigation (FBI) reports around 2,000 complaints a day. If you want to target U.S.-based clientele, using an Australia domain name is a good start. A .au domain registration demands strict requirements and validation protocols. Hence, there’s a significantly lower chance of data or security compromise.

2. Choosing a Domain Name

Here are a few tips on how to choose a domain name for your Australian website.

Use your business name as your domain name

If you’re already operating a company, use its name as your site’s domain name. This will not only help you establish brand consistency but will also prevent you from falling victim to cybersquatters and illicit, anti-competitive practices. You can rest assured that your business name remains secure and under your full control. 

Ensure the availability of your domain name

It’s frustrating to go through the .au domain name registration process only to find out that your chosen domain name isn’t available anymore. Make sure that your chosen domain name is still available and that you haven’t violated any trademark laws by first going through the Australian Business Name (ABN) registry. 

Optimize your domain name: Keep it brief and accurate

Adult internet users only have around an eight-second attention span. Moreover, they want website names that are easy to remember and type in the search or address bar. To accommodate these preferences, make your domain name short and simple.

It’s enough that it bears the main name of your company or brand. You can put the rest of the details on your landing page or other sections of your website. It is sufficient for the primary name of your company or brand to be prominently featured. Additional details can be effectively presented on your landing page or within other sections of your website.
