To earn yourself, every time you need not go out for the purpose. Money can be earned by doing home business too. But you should have an idea or a blueprint; of what exactly are you planning to do. One such idea is to become a Technical writer. A technical writer is basically a professional writer who can be able to write different types of technical data and documentation.
Appropriate domain name and TLD selection is very important for success of your online business website/blog.
A good domain name will contain 2 to 3 of your main keywords for the website that you have decided to create. Try different combinations using google adwords keyword tool and you will definitely be able to find some domain name with good TLD. If you don’t find and good domain name with .com, .net or .org tld, then you can consider hyphenated TLDs.
However, in such cases I usually reconsider my decision to create a website on that niche. As unavailability of good domain name signals that there is tough competition and there have been attempts to create a website on this niche.
