After joining a survey site, you provide some personal and demographic information, which legitimate survey sites will keep private. That information will be used in choosing participants to take surveys on certain goods and services. If you get selected to take part in a survey, you will be notified through mail to take a short survey to see if your profile suits that survey. When you are deemed qualified, you will be requested to take a longer survey.
