Multi-vendor marketplaces, like ThemeForest, can be very successful. Chose a niche and create a vendor website for it. Your marketplace could be anything, from a platform for local artists to sell their work on, to an online digital product store. Once set up, invite people in that industry to sell their products on your site. You take a percentage of their profits when items sell.
Is there a product or service that you are particularly enthusiastic about? If you are, you may be able to develop a website that is built around selling it. You don’t have to be the actual provider of the product or service either. There are many businesses that offer these products and will allow you to sell them on an affiliate basis. For example, you may be able to sell a product on your website for a commission of 20% or 30% of the sale price.
Be a mommy (or daddy) blogger. If you haven’t used your free time between changing diapers, washing clothes and shuttling kids around to hop on the blog bandwagon, it’s worth considering this potential source of income. And just because you’re a parent doesn’t mean you have to write about parenting issues. In fact, given that there already are so many blogs about life as a mom (or dad), consider writing about another topic about which you are passionate. The more original, entertaining and informative you are, the more likely you’ll gain followers – and you need an online following to make money.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.
I watched an episode of Shark Tank once where I was introduced to Major Robert Dyer. Major Dyer was pitching a new energy drink called The Ruck Pack Energy Drink. It’s not like the world needs another energy drink, but he was able to convince both Kevin O’Leary and Robert Herjevic, two of the investors on the show, to give him $150k in exchange for 20 percent of the company.
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. Russell Brunson often says that if you do a webinar every single week for a year, you'll be a millionaire at the end of it. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence.
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
There’s an excellent chance that you have one or several musical instruments sitting in storage that haven’t been used in years. Perhaps it’s a leftover from when you were in school, or even from your days playing in a band. Whatever the reason that you have it, it’s probably worth money if you can sell it. Brand-new instruments are ridiculously expensive, so people often look to buy used equipment instead, particularly if they are novices.
