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.

Viral marketing is a customer-focused approach, so the first step is to identify the target demographic for a product and what they value the most in products, requiring marketers to research and analyze demographic data. During the Blair Witch campaign, the filmmakers and main marketing agents for the movie were accomplished film students. They examined what made horror movies compelling for the demographic of teens to young adults they were targeting, as well as explored how that demographic shared information. They used this information to focus on their product's mystery, and they concentrated their early efforts on the Internet where they knew they would have the best chance of reaching a younger audience.

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.
Another option: Consider starting your own real estate investment group. This is a great way to team together with other small investors, either via pooling your money together or simply by learning from eachother. According to Joseph Hogue, CFA from PeerFinance101.com, “The common bond in all real estate investing groups is that you help each other compete against the big money players to get the best returns.”
Since then, P2P lending has exploded onto the scene. More companies like Prosper and Lending Club have jumped on the P2P bandwagon, and investors are beginning to realize it’s an excellent source of passive income. As an investor, you fund an account and loan small amounts (like $25) to a variety of borrowers across a broad set of risk levels, creating a diverse portfolio.
Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
Can you expound on the use of publicly-traded REITs as a passive income source? I’m 31 years old. No children. No wife. No dependents. (I am the closest thing to Ebenezer Scrooge you’ll ever see). My monthly expenses amount to less than $2,000 per month (most of which go to pay student loans) . I have a decent job making over $55K per year. I also have a $60K inheritance coming my way in a few weeks. I am absolutely crazy about achieving absolute financial independence, which for me would require a passive income of over $2000/month to cover my living expenses. I could achieve that in a mere couple of years if I were to save excessively and dump my savings (and inheritance) into a Mortgage REIT via the stock market, most of which are shelling out above 10% returns in dividend payments. Is this a good strategy for me? Or am I being too hasty and assuming too much risk?
Although it would be nice to earn little bit of extra income without putting in any effort, you’re going to have to put in some effort at the beginning. First, you must be clear about why you want to earn passive income. Is it that you want to support your existing lavish shopping? Is it that you feel uncertain about the future and want to have alternative sources of income? Are you finding it hard to earn enough regular income to support your family and yourself, therefore you need extra passive income?
A truly viral product emerged from targeting a truly viral problem in the digital age, known as attention deficit disorder. Allowing people globally to channel their nervousness into an entertaining handheld device has allowed for the viral spread of Fidget Spinners. The products modest beginnings spread virally through school children and later through to adults. We started seeing fidget spinners in social media, memes with fidget spinners, fidget spinners distracting people while crossing the street, and of course, fidget spinners in the impulse purchase section of your local supermarket. This little product achieved a viral marketing status through providing a ‘solution’ to a viral problem and bringing about a world full of fidgetty temptation.
