How to choose your domain name, or switch your current one
Changing your domain name extension is easier than it sounds. If you’ve decided to go with a com.au domain extension to replace your current website address, it’s important to preserve the progress you’ve already made.
This means making your current site visitors, subscribers and customers aware of the change well in advance. It’s also a good idea to hold onto any search engine rankings you may have and inbound links you’ve harvested from other sites.
This is where Google’s approved method, a 301 redirect, comes in handy. It’s essentially a set of instructions that is hosted under your current domain name to inform visitors the page has moved to a new location.
From here, the visitor is automatically redirected to your new domain. You can read more about 301 redirects, and find detailed instructions for switching, via Google Search Central here. If that sounds a little too technical, consult a specialist web developer who understands how to execute such a change with minimal impact.
