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.
I don’t really know much about those…I should take a look from a diversification standpoint. If you don’t mind me asking, what do you target for your net effective tax rate on your passive income? Also, I’m sure you’ve probably covered this somewhere, but how do you deal with healthcare? One more dumb question…have you found that you spend more or less money than you anticipated once you retired?

A short study of this web site reveals that a hugely important factor for success in startup companies is finding ways to acquire customers at a low cost. In the Business Models section, we looked at the perfect business model: Viral customer acquisition with good monetization. However viral growth turns out to be an elusive goal, and only a very small number of companies actually achieve true viral growth.


There is a specific tax definition of passive income, known as “passive activity” to the Internal Revenue Service. Passive income is any income you make without actively working or are materially involved. The IRS defines it as any rental activity or any business in which the taxpayer does not “materially participate.” Nonpassive activities, or active activities, are businesses in which the taxpayer works on a regular, continuous, and substantial basis.


Do you want to reach new customers by promoting your online store’s best products? One of the hottest ways to reach more of your target audience is through viral marketing. Of course, it’s not quite as simple as adding cute animals to your marketing message, hoping that a kitten sitting on top of camping gear is enough to get your website link spread to the masses. But we’ll breakdown what steps you can take to help you inch closer to success. In this post, we’re going to look at how businesses can skyrocket sales through viral marketing.
Some good writing here! I am a realtor myself and frequently get in touch with clients that consider buying a realty estate a conservative of investing. I once heard of a transport company in Vienna, Austria, which focused their entire profit on buying eventually every house available in the downtown for about 80 years. That must be some of a passive income!
How to Monetize: Affiliate marketing works well when you discuss products on your blog. For our fish tank blog, we would link to all the things you need to buy for an aquarium and then when people click on that link and buy that item (and other items they purchase with it with some exceptions) you get a percentage of the purchase. Amazon Associates is the best-known affiliate marketing program, but there are others like Impact Radius, ShareASale, Commission Junction, ClickBank and Rakuten too.
If you love design and you are an artistic person, selling digital products on Etsy could be a great way to earn passive income. Digital products require little maintenance, your customers will simply receive a link to download them (which means you don’t have to worry about shipping and returns handling). All you need to do is spend time upfront to create beautiful artwork! (Easy right?)
Awesome article…if this does not give somebody a clear roadmap, they probably were never going to get there in the first place! I’m kind of like you trying to figure out where to place “new” money and maturing CD’s in this low interest environment. Rates have to go up eventually…I dream of the days again where you can build a laddered bond portfolio paying 8%. I plan for a 5.5% blended rate of return, with big downside protection.
To fully understand the model, it’s useful to look at the second, and subsequent, cycles of growth. In the model above, only the new customers that were added in the prior cycle send out invitations. This is because it is highly unlikely that the entire population will continue to send out invitations every cycle. Every time I have looked at other blog articles or formula for Viral Growth, they appear to have gotten this part of the calculation wrong.
This video became a major hit because it directly addressed how phrases that are so commonly used can be detrimental to someone's self image and confidence. In the video, various men, women, and young boys are asked to "run like a girl" or "fight like a girl". Then young girls are asked to do the same, with a very different approach: They show strength and confidence in their movements. 
The reason to make use or virality, the ease in spreading and sharing, is however a double-edged sword. We cannot forget that in this type of campaign, a large part of the control falls into the hands of the users, and we risk the message being misinterpreted or parodied. On the other hand, a successful viral campaign can work miracles for your brand’s results.
