Your domain is what you type into your web browser's navigation bar to take you to your site.
Registering a domain name means providing it for a specified period of time, usually one year.
A domain name can be renewed and only you can use it, so if your domain is renewed, it will remain in your possession. With a domain name you can set up custom email addresses like yourname@yoursite.hu, which can be used to conduct business or communicate with your followers.
You can also use your domain name as a web address where your website can be found.
Or, forward a custom domain to an existing social media account, like your Twitter/Facebook/Instagram profile or Youtube channel.

A great domain name is a short, easy to type, and memorable URL that reflects your brand or your website’s subject matter and your visitors can type it correctly on their first try.
You should avoid using hyphens, number strings, and unnecessary words so that visitors can easily remember and find your site.

When your domain name is taken, what's the alternative?
