The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.

Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.
Look at products such as Hotmail, Facebook, YouTube, Gmail, Snapchat, dating websites, and Craigslist. They all have one thing in common: they are products that went viral. These are the ideal viral marketing opportunities as these products get better when more people use them. I don’t to discuss these properly, but it’s essential to know that they exist for a complete view of viral marketing.
If you are a photographer looking to diversify your income stream, putting together styled stock photo packages can be lucrative. For example, a package of 15 wedding-themed stock photos for $10. You can then market this to any bloggers or businesses who are in the wedding business for their use (photos of different engagement rings styles are super popular). Through this method, it’s possible to make a continuous stream of income off of photos you’ve taken once (similar to a licensing deal).
Viral marketing or viral advertising is a business strategy that uses existing social networks to promote a product. Its name refers to how consumers spread information about a product with other people in their social networks, much in the same way that a virus spreads from one person to another.[1] It can be delivered by word of mouth or enhanced by the network effects of the Internet and mobile networks.[2]
