Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
There always has to be one jerkoff that needs to correct someone’s information. Do you feel better now that you have made sure your voice was heard. Ok, so it doesn’t pay instantly, perhaps the author’s does. I do Field Agent and have $182.00 this month. It does not payout instantly either, but I did not think to be rude and comment that this person is wrong. Instead, I would like to thank them for compiling such a helpful list and I will be trying a couple of the suggested sites right away. Thanks so much and to the person who must show that he knows something we don’t know……hush.
29. Videos – This could be an entire section on it’s own. Many people have made money by creating YouTube videos. Evan of EvanTube is a kid and he has made millions by creating reviews of products that other kids his age would use. It’s not easy to get views into the millions, but once you do, you’ll start seeing some cash come in. Many bloggers have completely turned to videos to get their point across by starting a video blog.
You could easily do home organizing for people, an industry that has gained a lot of popularity since the debut of Netflix's hit series Tidying Up with Marie Kondo. If you're a tidy and organized person yourself, and you're good at organizing spaces, why not offer your services to people around you? You'd be surprised at how many people, even on your own social media feed, might take you up on doing something like this.
Getting businesses to advertise on your podcast, either at the beginning or end or both is a great way to create a revenue through podcasts. Most businesses won’t be keen to advertise on your podcast until you can prove a large number of listeners. Therefore, it is unlikely you will be able to start out from the get-go with sponsors. But once you accumulate regular listeners or a high number of downloads from iTunes, you can start to sell advertising space on your podcasts.
The downside with this model is that you are still trading hours for dollars, which is a violation of my holy trinity concept. It’s not necessarily the worst option – and many people enjoy the life of a high-paid consultant very much – but it does have the inherent limitation that a service is not replicable unless you personally do it yourself or hire people to do it for you, both activities that take time and/or resources.
The audiobook industry is booming, yet only 5% of books ever get made into audio format. If you’ve got a background in acting, or if people have said you’ve got a voice made for the radio, you can make extra money recording audio versions of independent and popular books. Sites like ACX connect authors with audiobook performers. So, whether you’re an author looking for more ways to sell your book, or an actor/voice actor looking to make some extra income, you can sell your services online.
Offer to watch children or pets. If you know anyone who has children or pets, you could easily begin a side gig as a babysitter or pet sitter. To let people know you’re interested, send out a group email describing your services, post an ad on Facebook, or tell friends and acquaintances about your availability in person or over the phone. You can also create a profile on a babysitting referral site like Care.com.
I myself was a pretty big Magic: The Gathering fanatic from 18 – 21 years of age. Though I didn’t setup any website about it, I did cojoin a site related to Dungeons and Dragons content and provided GM tools written in excel for download. At the time I never had much interest in branching out and starting my own sites for profit and 10 years later I started up my blogs. Had I only started ten years earlier I would be in a vastly different place than I am now, but as they say hindsight is 20/20
With apps being constantly developed, competent app developers are in high demand.

eBay: With eBay, the procedure is very similar. You simply start by becoming an eBay seller and stay in good standing by making sure your PayPal account is verified, and then you can sign up for your store. These three steps allow you to piggyback on eBay’s reputation, reach, and sales and marketing infrastructure in order to sell your own products.
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity.
