There are hundreds of “gurus” on Internet advertising themselves as market leaders and say that you can earn thousands of dollars with little or no effort. Do not believe all those. Most of them are scams and you will end up loosing your investment – either money or time or both.
If you have your own business already set up, you can expect to invest good amount of time, capital and effort. But, if you are looking for a new business opportunity beware of the nets in the Internet.
If you are planning to start a blog to earn money, DO NOT buy a domain name and host it right away. Because lot of people start writing their blogs once they get some thought, but slowly stops doing it after couple of months. Hence, you can start blogging with free blogging sites like www.blogger.com or www.wordpress.com and are doing it regularly then you can go a custom domain as per your ideas. You can buy the domain names from popular websites like www.godaddy.com.
