I almost called this article how I found out I was a mongoose, but it doesn't make sense until you go take the quiz. My friend Jonathan Rivera, you can find him at Real-TechGuy.com did a video and post about Surviving Your Serengeti. <– affiliate link.

The book sounds interesting and he gave it a great review I don't know much about the book beyond his review.  But their marketing has been amazing.

One of the things they are doing is a quiz that helps you determine what animal you are, that's how I found out I was a weasel. It's a simple quiz and we're all curious to find out if the quiz is "right." But on the quiz page they have three different ways you could virally share. #1 like the page on Facebook, #2 like the book on Amazon and #3 like ActiveRain on Facebook.

Once you've gone through the quiz they show you what animal you are and give you multiple ways to share your type. I'll detail three of them here:

#1 They ask you to share your results with your friends. This generates the wall post below 

#2 The ask you to share the Quiz which generates a wall post.

#3 They have Facebook and Twitter Share Buttons

That's not counting the links on the two sides of the and they have a Facebook Profile badge generator that I didn't get a screenshot of, but here's Jonathan's. He's a mongoose too. My guess is that most of my online entrepreneur friends will be mongooses because we're resourceful.

They hit it from all of the normal book launch channels as well, but how they used social media to virally promote was extremely well done. And it looks like it worked:

I'm buying my copy based on Jonathan's review, but their marketing was top-notch. You can learn a lot from this campaign.
One of the core take-away's is to not be afraid to use multiple method because you never know when someone with a large audience will share your page and drive a significant share of traffic.
