28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Online business is how I’ve made a living since 2003 and what has helped me retire early. I make over $40,000 a month through my blog. You can create your own blog here with my easy 15-minute step-by-step tutorial. You can start a blog for as little as $2.95 a month (less than a cup of coffee!). Create a blog and leverage it into affiliate sales or product endorsement deals. Consider topics like:
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. 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. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar.
19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.
You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low. You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
Job Boards. When you’re first starting out, you’ll have to go looking for work, and the best place to do that is on one of the online job boards. Places like Fiverr, Elance, Freelancer, and oDesk are today’s writers’ best friends. They allow individuals and businesses to post projects, and freelancers to bid on them. Take a look around the sites, sign up for the free access in the beginning, and then begin to place bids on the projects that interest you. It will take some trial and error to find your groove, but once you do, the jobs will start to roll in.
Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income. Over time, she was able to double and triple her rates until she could quit her full-time job to write. These days, she makes bank as a freelance writer and teaches others to do the same via her online course, Earn More Writing.
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. 
Research. You need to know what others are selling before you decide what wares you will offer. Lots of people sell handmade items, but those who work hard to make their items unique in some way are the ones who truly stand out. After you’ve decided on a product, check out the other sellers on Etsy and find what they’re offering, and then figure out how you can do it differently.
People are turning to audio and visuals when it comes to technical subjects. However, you should consider doing an ebook first and turning it into an audiobook through a resource like Audible's ACX platform. You can hire a producer either through a royalty share program, so you don't have to shell out upfront cash, or you can do a pay-per-hour hire as well.
