You Can Make 75$ / Hour by Participating in Google User Studies / Survey

Google is asking for participants for their user studies. They will pay handsomely - 75 $ / hour. Google is a reliable company and so you can be sure that there is no scam as with many other survey offers. You can even participate in a study remotely (from your computer), or fill in an online survey. There are four types of studies:

• Usability study at a Google office: Typically, you will use a Google product or prototype, and give feedback on it. You could either meet 1-on-1 with a Google researcher, or work as part of a group. Most studies are done at our HQ in Mountain View, California, but we have offices all over the world, so please feel free to sign up for this type of study even if you don’t live in the San Francisco Bay Area.
• Remote usability study: A Google researcher will call you while you sit at your computer, and ask you to try out a Google product or prototype via your internet connection, and give feedback on it. You can be anywhere in the world, but need to have a high-speed internet connection.
• Field study: Google researchers will come to visit you, and interview you about how you use computers or the Web. We won’t just show up at your door - we will always check with you, and make an appointment. Again, most of our researchers are based at our HQ in Mountain View, California, but we have offices all over the world, so please feel free to sign up for this type of study even if you don’t live in the San Francisco Bay Area.
• Online survey: you answer questions on the web or in an email, from your own computer.

In user studies and field studies, you will typically spend one to one-and-a-half hours with a Google researcher, almost always be during normal business hours. via Google
