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.
Companies like Uber and Lyft offer a great opportunity to make some quick cash. You'll need a clean driving record, a fairly new car and the authorization to work wherever it is that you live. If you have all of those things, you can work when it's feasible for you, whether that's in the middle of the day during rush hour, or in the wee hours of the night on a weekend. The choice is yours.
Become a freelancer in an area where you have expertise. If you have a skill that’s in demand, you can sell your services directly to clients who need them. Advertise your services on a personal website and look for freelancing jobs on sites like Upwork, Freelancer, and Fivrr. Additionally, hand out business cards and encourage happy clients to tell others about your work. Here are some ways you can earn money as a freelancer:[8]
There are actually more deals out there like this than you’d believe, thanks to the fact that sellers list used textbooks for low prices on Amazon all the time, not realizing they could trade that book into Amazon for more money. For example, you might see a Biology 101 textbook that has a used price of $45 and an Amazon trade-in price of $70 – meaning you could buy it and trade it right back in for about a $25 profit. 

Create a stylish and functional website. Elegant or funky, classical or hipster, your online store should reflect what you’re selling. No matter what your style is, it's important to give off a professional air. Since you won't be able to earn people's trust in person, your website will have to do the selling for you. Your site should be engaging, and most importantly, easy for customers to use when they're ready to make a purchase.[5]
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. 
Sell plasma. After passing an initial screening, you can usually sell your plasma for anywhere from $25 to $50 per donation. To qualify, you’ll have to stand in a long line or show up early, be willing to fill out a very personal questionnaire, and endure a painful needle prick or two. Still, selling plasma is a great way to raise money fast – if you can stand the hassle.
When you sign up for Trim, they immediately begin analyzing your spending and look for ways to reduce it. They’ll call your internet service provider and negotiate you a better deal on the same service. Same for your cable package (or any other recurring service you have). They’ll also look for hidden or otherwise forgotten about subscriptions and cancel those if needed. Think of them as your bill guard dog. No one gets by without their permission.

Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
Become an Amazon Associate and then use Keyword planner to find an in-demand niche: With more than a million different products to choose from and up to 10% commission the sales you drive, Amazon’s affiliate program is a great place to get started. Browse their available products and see what connects with you.

You'll just need to employ an easy tool like Sellfy in order to quickly sell PDF files (like an eBook) to your readers.
Launching and building a vacation rental business might require some sweat equity along with the right turnkey software solution to help you keep things organized as bookings ramp up, but if you have an acute attention to detail, then this is by far one of the best businesses you can start online. Of course, this does operate in the real world, but your web presence and marketing skills are really what define this business and helps it to succeed.

Get paid to search the Web. Zoombucks.com will pay you to use their online interface to search the web. To qualify, you need to be willing to download their search bar and use it for everyday Internet use. The only caveat that comes with this “gig” is that you might be paid in gift cards instead of cash. If you can parlay those gift cards into items you need to buy anyway – like groceries or gas – searching online can be a lucrative way to spend your free time.
