The Six Simple Principles of Viral Marketing

by Dr. Ralph F. Wilson

I admit it. The term "viral marketing" is offensive. Call yourself a Viral Marketer and people will take two steps back. I would. "Do they have a vaccine for that yet?" you wonder. A sinister thing, the simple virus is fraught with doom, not quite dead yet not fully alive, it exists in that nether genre somewhere between disaster movies and horror flicks.

But you have to admire the virus. He has a way of living in secrecy until he is so numerous that he wins by sheer weight of numbers. He piggybacks on other hosts and uses their resources to increase his tribe. And in the right environment, he grows exponentially. A virus doesn't even have to mate -- he just replicates, again and again with geometrically increasing power, doubling with each iteration:

1
11
1111
11111111
1111111111111111
11111111111111111111111111111111
1111111111111111111111111111111111111111111111111111111111111111

In a few short generations, a virus population can explode.

Viral Marketing Defined

What does a virus have to do with marketing? Viral marketing describes any strategy that encourages individuals to pass on a marketing message to others, creating the potential for exponential growth in the message's exposure and influence. Like viruses, such strategies take advantage of rapid multiplication to explode the message to thousands, to millions.

Off the Internet, viral marketing has been referred to as "word-of-mouth," "creating a buzz," "leveraging the media," "network marketing." But on the Internet, for better or worse, it's called "viral marketing." While others smarter than I have attempted to rename it, to somehow domesticate and tame it, I won't try. The term "viral marketing" has stuck.
