Pointing your personal domain to your Facebook or LinkedIn pages is a great way to set up an instant online presence, without having to build your own website. You’ll always control what your visitors see when they go there. A personal domain is a great choice for businesses as well. It allows you to control every aspect of your brand — even the address you give to your customers.
You can point your domain to your Facebook page for as long as you like. But once you build your own website, it will need its own domain. You can either stop using this personal domain for Facebook and forward it to your new website or choose a new domain for your website.
