One example would be that a brand like Coke or Pepsi wants to know more about what kind of people are buying their beverages. They might want to learn more about the age, gender, income, or location of the people who like or dislike their products. They might use this for marketing purposes or to make decisions about their future products. Brands like this spend a lot of time and money investing market research to get your feedback. You just get money for doing them a favor – it’s a total win-win!
