Companies often use online surveys to gain a deeper understanding of their customers’ tastes and opinions. Like traditional surveys, online surveys can be used in two basic ways: To provide more data on customers, including everything from basic demographic information (age, education level and so on) to social data (causes, clubs or activities the customer supports) To create a survey about a specific product, service or brand in order to find out how consumers are reacting to it. In contrast to traditional surveys, online surveys offer companies a way to sample a broader audience at a lower cost.
