Organic Traffic vs Viral Traffic?

A lot of people have no clue what the differences are between Organic Traffic and Viral Traffic. So to give a better understanding of the two, I'll write up a summary of them.

What is Organic Traffic?
Organic Traffic is when people use the search engines and/or links to get to your site. It's pretty simple.

What is Viral Traffic?
Viral Traffic is a whole other thing to tackle. It's usually a bit more involved. I'll give you an example. Let's say you have a company that puts out a little link code that keeps track of people's site statistics. People put that little statistic code on their site which also act's as a link back to you. It spreads without you doing anything.

You just basically have to set it up and then cross your fingers.Another good example would be something much more simple. Let's say you have a blog and you find some unique and popular information. You write about it, and the news spreads. People are quoting and linking back to your site as the source of information. You are not manually going around and placing links to your site, people are doing it for you.
