Among the first to write about viral marketing on the Internet was the media critic Doug Rushkoff. The assumption is that if such an advertisement reaches a "susceptible" user, that user becomes "infected" (i.e., accepts the idea) and shares the idea with others "infecting them", in the viral analogy's terms. As long as each infected user shares the idea with more than one susceptible user on average (i.e., the basic reproductive rate is greater than one—the standard in epidemiology for qualifying something as an epidemic), the number of infected users grows according to an exponential curve. Of course, the marketing campaign may be successful even if the message spreads more slowly, if this user-to-user sharing is sustained by other forms of marketing communications, such as public relations or advertising.
Thanks for asking. https://passiveincomemd.com/what-is-passive-income/ gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.
The list of passive income ideas could go on forever. As you search for the best fit, keep an eye out for ideas that show positive long-term track records. Do other people make money on the idea? Has it come back to bite someone who tried it? Some people ask me about passive income options like drink, vending, or other rental machines in public places. The bottom line? Don’t fall for any passive income ideas that promise a quick return or require huge amounts of money upfront. They will sabotage your other financial goals. Look for ideas that are steady, profitable, and trustworthy. Do your research. And never go into debt!
Etsy now allows you to sell digital products in your store. This can be anything from a picture that someone can download and frame to a guide on how to create a budget in PDF form. The possibilities for you to be creative are endless. The nice thing is, once you create a digital product for Etsy, you upload it and you can sit back and watch the sales come in (assuming your digital product is awesome).
If you have a blog or some other property that has visitors, you might profit passively via affiliate advertising. For example, imagine that you write a blog about movies. You might review some books about movies, and then link to them on Amazon so you get a cut of the purchase price when anyone buys books through the links. If you blog about hiking, you might promote some hiking gear you recommend on the blog, again generating passive income if anyone buys any of it.
Exploits common motivations and behaviors. Clever viral marketing plans take advantage of common human motivations. What proliferated “Netscape Now” buttons in the early days of the web? The desire to be cool. Greed drives people. So does the hunger to be popular, loved, and understood. The resulting urge to communicate produces millions of websites and billions of email messages. Design a marketing strategy that builds on common motivations and behaviors for its transmission, and you have a winner.
The ultimate goal of marketers interested in creating successful viral marketing programs is to create viral messages that appeal to individuals with high social networking potential (SNP) and that have a high probability of being presented and spread by these individuals and their competitors in their communications with others in a short period of time.
