Public Opinions clients consist mostly of companies or branches of the government who are looking for the opinions of consumers regarding the products or services they offer. The opinions they collect help companies develop new products, make existing ones better, and improve customer service. They also assist governments and non-profit organizations in advancing laws and policies that are in the public interest.

Most surveys will therefore ask you your opinions about different products or services you may use. Sometimes, they may invite you to test a new product, in which case, they would send you a product by mail and ask you to use it for a given time period and then send you a survey about the product. They may also invite you to participate in a discussion group.

The length of the survey and the number of reward points will vary from survey to survey. On average, surveys will take between 10-15 minutes to complete. The length of the survey and number of reward points given will always be clearly specified before you begin a survey. You can expect to receive up to 3 or 4 survey invitations per month.

You then exchange your reward points for a variety of rewards such as gift certificates, prize draws, cash payments, charitable donations and more.

However, watch out with trial offers and check you understand what you have to do to cancel, before you sign up, or you could find yourself with a subscription to something you don't want.
