28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Similar to writing reviews, you can become a freelance writer and make extra money writing articles and website copy. While you don't have to be a professional journalist to write for a website, it helps if you've blogged or had your own website where you blog regularly. Even better is showing that you have some experience in the niche in which you're trying to find a job.
Focus groups are a little more involved than paid surveys, but they are a bit similar. Rather than ticking off a yes/no to say what you think about a product or service, you're invited to participate in discussions about what you tried, or share your thoughts via webcam. Focus groups also pay more than paid surveys, and sometimes you may be asked to leave your home and visit a location to do them.
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.
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.
