Usability testers are asked to perform tests based on their demographic profile (education, knowledge of the web, age, social media use, etc.). They are then given questions to address and/or tasks to perform, such as registering on a website and then providing feedback online. Reviews usually take about 15-20 minutes and earn typically about $10 each. After completing a review, testers are not paid until the client accepts their feedback. Work can be rejected and unpaid for technical problems, lack of detail, or other issues the client determines. 
Something else I recommend is taking the free 7-lesson mini-course on general transcription offered by Janet Shaughnessy of Transcribe Anywhere. This will help you to understand if you're a good fit for a transcription career, what you can potentially earn, and also where to get started. Janet also has free legal transcription mini-course if you're more interested in going that route.
What It Is: Students in countries including Japan, Korea, France and Germany are looking for English speakers to practice with. Sessions focus on things like making professional small talk or running a meeting (trainers are provided with specifics on how to teach each topic, and are also trained themselves for two days before starting the job). Lessons take place either over the phone or on a live Internet video service like Skype — sometimes at night, because you're working with students in different time zones. You need to commit to a minimum of 20 hours a week at consistent times, and can work as many as 35 hours.
Pretty much every serious blogger and online entrepreneur I know has at least one virtual assistant. Think of a VA like an administrative assistant at a regular office building, except they are working remotely. Duties can include practically any administrative task you can think of – including handling emails, bookkeeping, completing sales, customer service, editing websites, and much more. Specializations in areas like social media management or online ad management is another option.
What’s more, it’s time to get those list-making muscles in working order. Without face-to-face communication, it’s easy to let things slip through the cracks, so you’ll need to find ways to be as organized as possible. You might find that you like to write things down in a notebook, or perhaps you prefer calendar notifications. Find what works best for you to keep you organized and on task.

Virtual assistants, commonly referred to as VAs, come in all shapes and sizes. Many companies will hire VAs if they are looking for help with online administrative tasks (email, calendar management, data entry, etc), but don’t necessarily want to hire a full time employee just yet. They’re the perfect work from home job for busy people that may need to drop their work at a moments notice, or have very sporadic availability.
