A domain is essentially a business’s address on the internet. It is often described as being equivalent to a person’s physical street address. Each website that is visited must consist of a domain name and a web server. The address or domain is a unique identity that directs a user to a specific website in the same way that one is navigated by GPS to a specific physical street address. The domain points the web browser to the server that stores the site’s resources. An easy-to-remember, relevant domain name can help establish business identity and improve search engine rankings.
Every domain has its own domain authority. The higher the domain authority, the better your search engine rankings. When linking out externally, it is important to link to other sites that have a high domain authority. By establishing a high domain authority for your site, you will increase the likelihood of other sites with a high domain authority linking to your site, which in turn further improves your domain authority.
