The word virus is never welcome in Public health. This is because Health personnel and all are at the mercy of any virus that enters a community. When the virus enters, even an ordinary sneeze from one person can spread the disease in the whole community, and before we are aware everybody and their dogs get infected. However, in Internet Marketing this viral effect is highly encouraged especially when it comes to building your list.. And you can do that powerfully with an e-book to spread your message. 

Though there are many and varied  ways of building your list, the basics are the same. You certainly need a:

• A Squeeze page containing an opt-in section
• An irresistible Free Offer or Give Away  to ethically "bribe" your prospects or visitors to release their contact details. It has been found out  that one of the best offers you can give away is an ebook.

And how do you do that? 

• First, you must create the eBook, because it is a simple fact that you cannot give what you don't have. The eBook must be a really content rich one full of interesting and informative facts.
• It must have links to your squeeze page.
• Next, allow people to recommend or give the book to other people all over cyberspace. Let this be one of the rights you give people when they download their copy. The incentive is to make it clear that this book is free to give away, either by posting it on their websites or using it as a bonus product or bundle it with other products.
• To start with, give it to three people. In the book, encourage those three people to give the eBook to their friends and family. The trick is that they can download the book only from your website by first giving you their contact details.
• Most importantly, make sure that you send a clean and neat eBook out to the world. It is imperative that you double-check the spelling and grammar because obvious errors can be very disastrous and reflect negatively on you.Next, test all links to be sure that they reach the intended target.
• Post your eBook to eBook directories.

The sum effect of all this is that your eBook becomes your Viral List Builder Tool. Before you realize it, the eBook is spreading across the Internet uncontrollably like a virus. Digital information as you are already aware, duplicates and replicates easily and quickly so much so that you would be amazed at the thousands of people who are reading your free eBook.
