Acorns rounds up your everyday credit and debit transactions and automatically invests the spare change for you. It's only $1 a month and free for college students with an .edu address for up to four years from the date of registration. You'll barely notice the micro-investments of spare change, plus the Found Money feature invests money in your account when you shop with Acorns partners such as Macy's, Nordstrom, and Walmart.
I almost didn't list Swagbucks here because, while it's a great rewards site, they list in their terms that you can't expect for up to 10 days after you cash out. However, it's still an option to earn fast cash because some people report getting paid much faster than this. You can redeem you SB (Swagbucks) for Amazon codes, Paypal cash, and gift cards to popular merchandisers among other things. These points build up quickly thanks the the large number of things you can do on the site to earn. I've used this site and been paid many times.
Good post, Erica. You have provided a good list on how to make money online – scam free. I would go for ‘Help local businesses develop an online presence’ and ‘Interview other people and sell the interviews’ as these options would help me to interact with other businesses as well as other businessmen. This is a good way to network yourself and make your own circle of friends which may lead to something better.
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.
Walk around your neighborhood or town and I’m sure you’ll see tons of great local businesses with terrible design. However, with increasingly easy-to-use tools like Adobe Illustrator, Venngage, Stencil, and Visme, just about anyone with a creative mindset and a good amount of motivation can start making money online by being a graphic designer for local companies.
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.

Sites like Share-A-Sale and Amplifinity provide referral fees. Vendors set the referral fees they're willing to pay and for what services. When the transaction happens, you get paid by the company for introducing a new customer to them. uRefer also allows merchants to set up referral programs for introductions and meetings, in addition to any transactions made.
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. 
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
