Domains are deemed “premium” and expensive if they are memorable, and easy to spell; two branding elements that are normally very expensive to acquire.
Premium domains also give customers a sense of trust and authority. Users will, for instance, have more trust in doing business with www.fonduri.ro versus www.fonduri-xxx-.ro
Premium domain names can effect search engine rankings and help with link acquisition
Depending on the name and its vertical, certain premium domains carry large volumes of direct type-in traffic
A premium domain name is the perfect base for all non-internet based advertising like billboards, print ads, TV, radio, etc, Because premium domains are short and memorable
As a conclusion, a premium domain means besides all these extraordinary advantages and a lot of money
