Let’s take it from the top. I’ll use an example. My name is Suzanne and I want to build a website to promote my consulting business. So I start to look for a domain name, something unique, catchy, that people will remember. I come up with something I like. The next step is – is the domain available? For example I’ll use my domain. There are only so many Mark Koszyks in this world. Hopefully I’m the first one that wants to use my name as a domain.
What I do – and what I suggest – is determine a domain I like, and a few alternatives. I then go to any domain register (seeing as nothing is free in the world, domain registrars serve the purpose of helping you find an available domain – and claiming it for your use). Going back to my example of “suzanne.com” – any registrar tells me this is not available. So, remembering my suggestion of having a few alternatives – I go to plan B. That might be “Suzanne-Consults.com”, or something else. When I find one I like – I buy it and I’m on my way.
The last thing is what is called the top level domain. More below on that below.
