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.
A popular tactic to make money on social media is to pay for advertising affiliate products. Create ads for particular affiliate products that are big sellers and have a high yield. Then target these ads at specific custom audiences to ensure your ads are viewed by those who will have an interest in the product you are promoting. If viewers click through your from advert to the product page and make a purchase then you will earn an affiliate fee.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
