Provides for effortless transfer to others. Public health nurses offer sage advice at flu season: Stay away from people who cough, wash your hands often, and don’t touch your eyes, nose, or mouth. Viruses only spread when they’re easy to transmit. The medium that carries your marketing message must be easy to transfer and replicate: email, website, graphic, software download.
Personal finance software can go a long way in helping you to take control of your money and meeting your financial goals. It’s important to note, however, that some focus more on budgeting and expense tracking while others prioritize investing portfolios and income taxes. Explore several different programs and read reviews to find the one that’s right for you.
The ALS Ice Bucket Challenge started in 2014, which was an online effort to raise awareness for people with Amyotrophic Lateral Sclerosis (ALS) disease and to raise funds. The campaign was able to raise $115 million in a span of just eight weeks! The challenge for people was to pour a bucket of ice-cold water over their head and challenge minimum three people to do the same and make a donation to The ALS Association.
Decision-making process seems to be hard for customers these days. Millers (1956) argued that people suffered from short-term memory.[57] This links to difficulties in customers' decision-making process and Paradox of Choice,[58] as they face various adverts and newspapers daily.[59] Influencers serve as a credible source for customers' decision-making process.[49][41] Neilsen reported that 80% of consumers appreciated a recommendation of their acquaintances,[60] as they have reasons to trust in their friends delivering the messages without benefits[60] and helping them reduce perceived risks behind choices.[61][62]

This is a venture that is growing rapidly. You can create videos in just about any area that you like — music, tutorials, opinions, comedy, movie reviews — anything you want . . . then put them on YouTube. You can then attach Google AdSense to the videos, which will overlay your videos with automatic ads. When viewers click on those ads, you will earn money from AdSense.
The first thing that we need to calculate is the number of new customers that each existing customer is able to successfully convert. This turns out to be an extremely important variable, and is known as the Viral Coefficient. The formula to calculate the viral coefficient is pretty simple: multiply the number of invitations by the conversion rate.
This is where my previous mention of “America’s Funniest Home Videos” becomes relevant. A large number of successful viral marketing campaigns involve real people reacting to imagined situations. Think about TNT’s ‘Drama Button’ campaign. It brought the drama of an intense show onto the streets of Belgium, shocking the real people on the streets. People loved it because they could see themselves in those reactions.

Crowdfunding, the process of pooling dollars from a large population of people to fund a larger project, has significantly increased in volume over the past several years. According to Statista, $34.4 billion was raised in the United States through crowdfunding in 2015. In 2012, this number was $2.7 billion. That number continues to trend upward as new crowdfunding options become available.
​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.
Many entrepreneurs reading this post will realize that they may not have the means to achieve true viral growth (where they have a Viral Coefficient of greater than 1). Rather than giving up, it is worth considering a hybrid viral model. In the hybrid viral model, you make up for the shortfall in customers by acquiring those through some other means such as paid search, or SEO.

To give you a preview of this post, what you will learn is that there are two key parameters that drive how viral growth happens, the Viral Coefficient, and the Viral Cycle Time. To fully illustrate the arguments, I have included two spreadsheet models (embedded) that you can play with interactively to see how viral growth works. There is a risk with this level of depth, that some readers will find this too technical, and if you find yourself reacting that way, may I recommend that you jump straight to the conclusion, which is under the heading Lessons Learned towards the bottom of the article.
Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.
​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.
Working with people outside of your usual industry can help you create a buzz for both of your companies. The TV show The Walking Dead teamed up with UC Irvine to create an open online course on what a zombie apocalypse would be like. Zombie lovers ate it up like free brains. Both the show and the university benefitted. HP teamed up with Kiva to allow HP employees an extra $25 to donate to the Kiva project of their choice. Both HP and Kiva gained exposure, while worthy charitable causes received funding.
Real(ly) beautiful: A 2013 campaign by Dove featured a police sketch artist listening to how women portray themselves and how another person describes them. The two images are then compared side-by-side, with the women’s “self-portraits” being far more critical and negative than the others. The ad has attracted more than 64 million views on YouTube. (1)
Non-fiction e-books that educate your potential audience on specific topics like finance, online marketing, and business are going to make you more money than fiction books. Of course, there are always exceptions and you could write the next Harry Potter book, but if you want to create some residual income opportunities quickly, I would suggest you go for what sells first!
Message: Only messages that are both memorable and sufficiently interesting to be passed on to others have the potential to spur a viral marketing phenomenon. Making a message more memorable and interesting or simply more infectious, is often not a matter of major changes but minor adjustments. It should be unique and engaging with a main idea that motivates the recipient to share it widely with friends – a "must-see" element.[22]
