Viral marketing refers to an online marketing method that uses your name or the product you are selling spreading among people online as a virus like the flu would. There are many tools you can use for viral marketing, and the Ebook is one of the finest.
Anytime you offer an Ebook for free that people really like, they will generally pass it along to others. The referral power of the links you will include in the Ebook can bring interested people flocking to your website. These people will tell more people about your Ebook, and the cycle continues. This is viral marketing at its finest.
You want your Ebook to look professional, and you should also make sure you choose a subject that fits within your niche. For example, if you are selling an electric fence system for canines, your Ebook could be about dog nutrition or dog training. Almost anyone who has a dog would be interested in an Ebook like this, and may also be a potential customer for your product.
