Viral Marketing is the concept of getting enough visitors to recommend or pass along your website address product name, service name or product such as an ebook. etc. to others while getting those people to do the same thing. Obviously this creates a dramatic snowballing effect that will spread like wildfire!
Consequently, if this process has a low conversion rate or lack of interest, then it will fizzle out quicker than a melting snow ball.
Viral marketing increases the amount of your prospects, customers, and leads, with zero effort on your part. Once the initial viral marketing campaign is set up, there's nothing for you to do other than launch it and see if it takes flight and continues to grow. The only need for an further advertising or internet marketing would be so you're starting out with a bigger snow ball and a steeper hill to roll it down.
Viral marketing is a strategy that is used to persuade people to pass along a message. This is similar to word of mouth marketing.
