But as with everything, there are cons to go with the pros. While a good viral marketing campaign can bring massive awareness about your brand in a cost-effective manner, it also has the capability to dilute your brand. Or at its very worst, build negative buzz regarding your brand and products. This is when “too much of a good thing” may just hurt your work in building your organization’s credibility.

For example, you might take photos and have them available for a fee at sites such as shutterstock.com or istockphoto.com. Similarly, you can create and upload designs at sites such as zazzle.com and cafepress.com, where people can buy them imprinted on shirts, mugs, and so on. Similarly, if you write an e-book (which can be as short as 6,000 or so words), you might find that people are interested in buying it, perhaps via Amazon.com's direct publishing service.
I am still working on my passive income, however I like multiple income streams even more. My favorite is capital gains because it is one of the lowest rates. One of the best passive income streams is a pension/Social Security. As I near retirement, I like the concept of it supporting my needs and my 401k supporting my wants. In addition, my brokerage accounts are all at capital gains rates. Don’t misunderstand, I am still working on adding more because I like multiple income streams!
Most credit card companies offer sign-up bonuses to entice you to open a credit account with them. As long as you don’t spend money just to hit the minimum balance and always pay your balance on time, this can have a minimal impact on your credit score while earning you hundreds – or even thousands – of dollars a year. Some of the best travel credit cards offer 100,000 points to new accounts when you meet reasonable spending requirements.
Passive income differs from earned income and portfolio income in a variety of ways. Passive income is generally defined as a stream of income earned with little effort, and it is referred to as progressive passive income when there is little effort needed from the individual receiving the passive income in order to grow the stream of income. Examples of passive income include rental income and any business activities in which the earner does not materially participate during the year.
While compiling this list, I did my best to avoid scams, and stick with practical ideas that work. I have tried many (but not all) of these ideas. Some of these helped me earned a few dollars here and there, but there are some that helped me earn extra money on the side every single day — and some are still providing me with revenue! Note that not all ideas will fit your skills and abilities. What works for you depends on your abilities and your current financial situation.

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.
