Hi fakankun The moment you have a domain name, no matter what it is or its extension, that generates an income, you have a good domain name.

If it is not a premium domain, your aim should be to grow the domain and turn it into a website and generate income from it.
In short, a premium domain name is a name that can be used to launch a profitable business online. These domain names have a certain set characteristics that make them more valuable and more expensive than just any other domain name. The following characteristics will define a premium domain name: 1. A Commercial Domain: The premium domain name is typically a commercial domain.

The premium domain must not be easily confused with another domain. 3. A Short and Memorable Domain: A premium domain is a short and memorable domain. Customers must be able to access the website without any problems when typing it into a browser. 4. A Meaningful Domain: A premium domain is generally a domain with a specific meaning. If two words are used to make out a domain name, the words must be used correctly in order to provide accurate meaning to the domain. 5. A TLD Extension: A domain name can be premium in any extension, but premium domains in the .com, .net and .org extensions are far more valuable than any other domain extensions. A premium .com domain will have the highest value. 6. Spelling: A premium domain name must be spelt correctly. Typos in domain names will remove the premium status of the domain name. 7. Hyphens and Numbers: The premium domain name will not consist of any hyphens or numbers in the domain. Domains with hyphens or numbers will lose its premium status. 8.

The golden rule, however, is that a premium domain will not consist of more than 3 words combined. 10. Stats: A premium domain will already receive traffic before it is listed in search engines. This traffic will be called Type-In traffic. This happens when a person, who needs information on cars, opens his or her browser and type www.cars.com in the browser – without conducting a search on search engines. 11.
