Medium is an online community where anyone can post articles and essays and get them in front of their audience of millions of monthly readers. While it can be a great place to build your audience for your own blog or find customers for your consulting business, with Medium’s new Partner Program, you can now make money online whenever someone reads your articles. Register for free and you can choose whether your articles are freely available or only readable by those people paying $5/month for a premium Medium membership. You’ll make money based on the amount of people who read and engage with your posts each month.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
Today's post is a ginormous list of 100 ways to earn extra cash online. Each listing will link directly to the site if applicable so you can sign up or check it out. I've either tried or thoroughly researched the sites listed, so they are legit to the best of my knowledge. I've also broken everything down for you by category to make browsing much easier.
The two popular ones are Poshmark and TheRealReal. Both make it dead simple to sell (and buy!) luxury items. The RealReal will pay you 60% of the sale price (more if you sell a lot) and Poshmark has a tiered commission structure. Sale prices under $15 pay a $2.95 flat fee and everything else is just 20%. Tradesy is another company and they take just 9%.
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. 
A site called User Testing will actually pay you a fee to evaluate websites. It typically pays you $10 for each video that you review – which typically takes about 20 minutes. If the work is there, and you are particularly good at it, you could earn up to $30 per hour. That’s a pretty solid pay rate for a work-at-home job. You wouldn’t have to work a whole lot of hours to generate a decent part-time monthly income.
Become a freelance writer or editor. If you have a passion for storytelling or a background in writing or editing, it’s possible to find freelance writing or editing work online. To search available job openings, check out sites like UpWork.com and Problogger.net. You can also check traditional job sites such as Indeed.com and enter “telecommute” or “anywhere” in the location field.
However, there are ways for stay-at-home moms and dads to earn a bit of extra cash to supplement the family budget without leaving the house or sacrificing time with the kids. In fact, here are 10 money-making opportunities that can be pursued when your children are at school or asleep, or possibly even when they are awake and demanding your attention. The earnings potential is modest, and not every opportunity will be right for you, but over the course of a year you could pocket hundreds – and possibly even thousands – of dollars.
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
