A domain name is a website address such as www.mywebsite.com To become the owner of a domain name you need to register it on a yearly basis at a domain registrar such as NameCheap. If a domain is not renewed it expires and becomes available to the public.
A domain name can be registered even if a website doesn’t exist so there is no need to wait until your site is ready. In fact the longer you wait the harder it will be to get a website address that looks and sounds nice.
How To Choose A Domain Name
A website address should be easy to remember and reflect what your site is about. For example this site’s domain is www.EasyHtmlCode.com because it endeavors to teach HTML in a simple, easy to understand manner…and because www.HtmlMadeEasy.com was already taken. Told you you shouldn’t wait too long to register a domain.
Don’t check the availability of a domain at the registrar unless you are ready to buy at that moment because there are folks who keep tabs on what domains people show an interest in. They then register it and put it up for sale at a much higher price hoping you will want it badly enough to pay for it. Instead type the domain into the browser address bar to see if it returns a website. If no website pops up chances are the domain is available for registration.
