Usability testing involves testing out websites, apps, software, etc. and sharing your feedback and/or helping developers find bugs and problems. What's great about these opportunities is that almost anyone can do them and you likely won't need any equipment you don't already have. Each site listed below pays differently, but most pay in cash — not redeemable points.
So, I put together a free master course for you to take that spreads out all of the work involved in starting a blog, into a series of action-packed lessons. My free course breaks the entire process of starting a blog down into an incredibly simple 7-day process for going from 0 to publishing (and promoting) your first blog post in just 1 week. I can't recommend it enough.
Understand how a niche website works. A niche website focuses on very targeted, specific information. The content must be specific, useful and interesting to your target audience. Successful niche websites get anywhere from 1,000 to 10,000 visitors per month.[5] You build content on a particular keyword, and you make passive income with Google Adsense or through affiliate links.[6] 

Rather than making money through subscriptions, YouTube channels are based on a traditional advertising system. Meaning the more viewers you get, the more you make. Once you’re approved for the YouTube Partner Program and can start including ads on your videos, with every 1,000 views, you will make approximately $2-$4. Which might not seem like a lot, but if you have 100 videos with 5,000 views a month each, that would be $1,000–$2,000 already. Just imagine if your videos start hitting millions of views!
Research selling prices of items similar to yours. Look up completed sales or current listings of items similar to yours. Find the high- and low-end prices, and price your object around the median price level. If you want your item to sell quickly, price it at the low end. The condition of the item also affects the price. Items in poorer condition should be priced at the lower end. Also, consider how many listings there already are of items similar to yours. If many similar items will be competing with yours, you may have to set the price lower to get the sale.[28]
Our first overlooked opportunity is selling your knowledge. In this instance, we are talking about creating a course or eBook that you can make available for purchasing online. Because of the automation available today, you may be able to put in the work once when creating your packaged information and then enjoy those checks coming in for months or years to come.
