How do paid survey companies pay you?

Paid survey companies conduct market research on behalf of companies that produce products and sell services. They offer you cash and prizes in exchange for your time and consumer opinions. Companies are constantly trying to improve their products, and before they launch a new product and an expensive advertising campaign, they need to know about consumer preferences. Online surveys are an easy way for collecting consumer opinions to guide these companies. In exchange for you opinions they will compensate you with cash, prizes, or sweepstakes entries. Some of them even send you sample products, and pay you to conduct product evaluations.
