Use the best keywords. When searching online job boards, don’t use the phrases “work from home” or “work at home” because those are commonly used by scammers. There are about 70 scam jobs for every one legitimate, work-from-home job, so use phrases like “remote job,” “telecommuting job,” and “virtual job” to steer clear of scams and find real, professional opportunities.
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. 
Recruiting the right testers can be the greatest bottleneck in lean UX. Recently, my company had a trial enterprise account with UserTesting.com. One of the expanded enterprise features is the ability to write specific screener questions that allowed us to target an elusive population segment from UserTesting.com’s testing panel. This saved us so much time and money and was simple to use.

You can choose to use the tool and have your own batch of testers log to your websites or prototypes and record their experience for their usability, functionality, navigation, etc. Or you can choose to opt to have UserTest.io’s own professional testers check your sites and hear their expert opinion on your site’s navigation, ease of use, design, and more.
Re-selling web hosting will enable you to make money hosting your own client’s websites. Large hosting companies like HostGator allow you to white label their hosting services. You could start your own hosting business or, if you are a web designer, include hosting into your web design packages. And the best of it is the hosting companies take care of the hosting for you, so all you need to worry about is selling.
Now, it’s time to start creating and uploading content. Make sure you’re using a high-enough quality camera (most smartphones will work but I’d suggest at least having a tripod so your footage isn’t shaky), but don’t worry about being perfect at first. The beauty of YouTube is that you can continue to test out different content and styles as you find what works for you. Instead, stick to a regular schedule to build up your subscriber base.
If you have nothing of value to sell from home then retail arbitrage might be a better option for you. Many people partake in arbitrage to earn a little extra money, and for some, it has even become their full-time job. Retail arbitrage is the buying of goods at a low price and then selling them on a different platform at a higher price. Sales in shops provide ideal opportunities to pick up products for next to nothing. These can then be sold on eBay or Amazon for higher amounts, making you a nice profit.
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.
