If I was given a choice to decide on one method that is the best way to earn an online income it would be a hard one but I would probably say, make money blogging. This method has so many variations to it, it is absolutely unbelievable.
You could make money blogging from only one blog which you posted to several times a week or you could make money blogging from a blog empire which could consist of tens or even hundreds of niche specific blogs which all advertise affiliate programs or even google adsense.
The choice is yours really but that example is really just the tip of the iceberg. In my opinion one of the best things about make money blogging is the fact that it is so cheap to get started. You could even start for nothing if you go down the blogger.com route, not that this would be my number one choice but if funds are extremely tight it is better than nothing.
If you build your blogs using the wordpress platform your only outlay would be a domain name and some hosting, I am talking very small amounts of money for the outlay here and if you step back for one minute to imagine what you could achieve from this outlay, well, most people would thing that you were mad.
Make money blogging, and if you stick with it you could very well be making more money whilst you are sleeping than many people earn for working all the hours that God sends.
To your make money blogging success
