One secret you need to know about how this is done is that it requires a lot of hard work. I usually laugh when I see people trying to promote their sites with a dozen or so articles every month. Those are actually the kind of numbers you should be looking at for daily article generation. By the way doing that number of articles per day is very simple if you know how. There is a technique you have to learn how to use and you will easily produce a high number of articles every day without even breaking into a sweat.
For you to generate high enough traffic to your blogs for you to earn a living from them, quantity alone will just not cut it. Quality too is critical.
Your articles must be able to address pressing problems that your potential clients are facing. And what is more you must convince them that you have enough knowledge and expertise to deal with them effectively.
Last but certainly not least. You must know which article directories to use to create a buzz about your blog posts and articles so that the articles have a chance to virally spread complete with the links pointed back to your site.
If you are able to do these three things, then you will not struggle too much nor for too long before you find that you are quite capable of learning a living on the web working your blogs, just like I do.
Just to remind you the three things are;
a) You must be able to produce the right quantity of articles. Or alternatively pay someone else to produce them for you. Incidentally good online writers are very affordable. The minimum quantity of articles required to make an impact online is 150 per month. In my weekly newsletter I show you a simple technique you can use to produce more articles than you need. And you DO NOT have to write them all nor do you need to pay somebody else to do it.
b) The articles must be useful and of a good quality, mainly addressing problems faced by your potential clientele.
c) You must know which article directories to post the articles in for maximum effect and generation of traffic.
