Article marketing will help your business grow for multiple reasons. Articles tend to become viral, so your message is spread throughout the Internet ... which in turn increases your traffic and sales. Having articles published in a variety of places also increases your credibility by establishing yourself as THE expert in your niche.
Being in the affiliate marketing business is not that hard now with the Internet at your disposable. It is much easier now compared to the days when people have to make use of the telephones and other mediums of information just to get the latest updates on the way their program is coming along.
