People often likes to think that the shorter a domain is the better it is and I am here to say that the saying is not always true. Of course WZJZ is pretty short and you only have to remember 3 letters and one letter you have to remember twice. But imagine a domain like ThisIsADomain.com – that domain is fairly easy to remember and contains 3 times more letters so.
It shouldn’t be the length of a domain that determins its value or even importance, but the simplicity of how your visitors can remember it. There are big companies with huge domains and people still remember because its the company’s name or at least abbreviations of it. The shorter doesn’t always necessarily mean the better it is. Just depends on how you raise it.
