(71)The Internet is a powerful and cost-effective tool for conducting market research regarding consumer behavior, identifying new markets, and testing consumer interest in new products. Although telephone or shopping mall surveys(调查) will continue, interest in interactive Internet research methods is on the rise. (72) Online market research utilizing the Internet is frequently more efficient, faster, and cheaper, and you have the ability to get a more geographically diverse(不同的) audience than those found in offline surveys. Furthermore, the size of a market research sample is the key determinant of research design. (73) The larger the sample size, the larger the accuracy and the predictive capabilities of the results. On the Web, one can conduct a very large research study much cheaper than with other methods (20 percent to 80 percent less). For example, (74) telephone surveys can cost as much as $50 dollars per respondent. This may be too expensive for a small company that needs several hundred respondents. An online survey will cost a fraction of this.
Internet-based market research is often done in an interactive manner by allowing personal contacts with customers, and it provides marketing organizations with greater ability to understand the customer, market, and the competition. For example, it can identify early shifts in products and customer trends, enabling marketers to identify products and marketing opportunities and to develop those products that customers really want to buy. (75) It also tells management when a product or a service is no longer popular.
