Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses (after going down the path of learning how to make a website) on their own blogs. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
In 2017, there were almost 90 million pet dogs in the US. Which has opened up a huge opportunity to make money online as a dog watcher or sitter. Specialized sites like Rover or Care.com connect pet owners with pet walkers, sitters, and boarding houses to help look after their best friends when they’re at work or on a trip. If you’re an animal lover, you can make extra money and get to spend some quality time with a furry friend.
Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
Take surveys. You can earn $50 to $100 per month in cash and products by taking online surveys. Find survey sites by searching for “paid survey sites” online. Sign up for several survey sites to increase your chances of being selected for higher-paying surveys. Register with an email address, and check your email often so you can respond quickly to survey offers.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs. 
More than half a billion products are sold on Amazon every month, making it an incredible opportunity to make money online. But, like everything else that involves making money online, you have to do quite a bit of work to earn it. One option on Amazon is to find products that are already made and buy and sell them at a discount. For example, you could research generic products such as clocks, keychains and mugs to attach to your brand.
There are quite literally hundreds of clever ways to make money online. From taking online surveys, to renting or selling your old clothes, flipping your iPhone to someone in a different country, and even buying low-cost products locally, just to resell them for a higher price on Amazon. There’s truly no shortage of unique ways to make money online.

26. Services – You can offer a paid service, such as life coaching, blog coaching, goal setting or financial planning. Just be sure to investigate all the legal implications and make sure you’re not claiming to be a professional if you’re not one. With a service like this, you’re basically using your blog to sell yourself. You’ll need to convince people that you’re worth buying and then be able to back up your claims once they purchase your service.

A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.[24]
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
